-2.2 SLIB
-========
+2.1 Distributions
+=================
-[SLIB] is a portable Scheme library meant to provide compatibility and
-utility functions for all standard Scheme implementations. Although
-SLIB is not _neccessary_ to run SCM, I strongly suggest you obtain and
-install it. Bug reports about running SCM without SLIB have very low
-priority. SLIB is available from the same sites as SCM:
+The SCM homepage contains links to precompiled binaries and source
+distributions.
- * swiss.csail.mit.edu:/pub/scm/slib-3b1.tar.gz
+Downloads and instructions for installing the precompiled binaries are
+at `http://people.csail.mit.edu/jaffer/SCM#QuickStart'.
- * ftp.gnu.org:/pub/gnu/jacal/slib-3b1.tar.gz
+If there is no precompiled binary for your platform, you may be able to
+build from the source distribution. The rest of these instructions
+deal with building and installing SCM and SLIB from sources.
-Unpack SLIB (`tar xzf slib-3b1.tar.gz' or `unzip -ao slib-3b1.zip') in
-an appropriate directory for your system; both `tar' and `unzip' will
-create the directory `slib'.
+Download (both SCM and SLIB of) either the last release or current
+development snapshot from
+`http://people.csail.mit.edu/jaffer/SCM#BuildFromSource'.
-Then create a file `require.scm' in the SCM "implementation-vicinity"
-(this is the same directory as where the file `Init5e5.scm' is
-installed). `require.scm' should have the contents:
+Unzip both the SCM and SLIB zips. For example, if you are working in
+`/usr/local/src/', this will create directories `/usr/local/src/scm/'
+and `/usr/local/src/slib/'.
- (define (library-vicinity) "/usr/local/lib/slib/")
-where the pathname string `/usr/local/lib/slib/' is to be replaced by
-the pathname into which you installed SLIB. Absolute pathnames are
-recommended here; if you use a relative pathname, SLIB can get confused
-when the working directory is changed (*note chmod: I/O-Extensions.).
-The way to specify a relative pathname is to append it to the
-implementation-vicinity, which is absolute:
- (define library-vicinity
- (let ((lv (string-append (implementation-vicinity) "../slib/")))
- (lambda () lv)))
+File: scm-5f2.info, Node: GNU configure and make, Next: Building SCM, Prev: Distributions, Up: Installing SCM
-Alternatively, you can set the (shell) environment variable
-`SCHEME_LIBRARY_PATH' to the pathname of the SLIB directory (*note
-SCHEME_LIBRARY_PATH: SCM Variables.). If set, the environment variable
-overrides `require.scm'. Again, absolute pathnames are recommended.
+2.2 GNU configure and make
+==========================
+
+`scm/configure' and `slib/configure' are Shell scripts which create the
+files `scm/config.status' and `slib/config.status' on Unix and MinGW
+systems.
+
+The `config.status' files are used (included) by the Makefile to
+control where the packages will be installed by `make install'. With
+GNU shell (bash) and utilities, the following commands should build and
+install SCM and SLIB:
+
+ bash$ (cd slib; ./configure --prefix=/usr/local/)
+ bash$ (cd scm
+ > ./configure --prefix=/usr/local/
+ > make scmlit
+ > sudo make all
+ > sudo make install)
+ bash$ (cd slib; sudo make install)
+
+If the install commands worked, skip to *note Testing::.
+
+If `configure' doesn't work on your system, make `scm/config.status'
+and `slib/config.status' be empty files.
+
+For additional help on using the `configure' script, run
+`./configure --help'.
+
+`make all' will attempt to create a dumped executable (*note Saving
+Executable Images::), which has very small startup latency. If that
+fails, it will try to compile an ordinary `scm' executable.
+
+Note that the compilation output may contain error messages; be
+concerned only if the `make install' transcripts contain errors.
+
+`sudo' runs the command after it as user "root". On recent GNU/Linux
+systems, dumping requires that `make all' be run as user root; hence
+the use of `sudo'.
+`make install' requires root privileges if you are installing to
+standard Unix locations as specified to (or defaulted by)
+`./configure'. Note that this is independent of whether you did
+`sudo make all' or `make all'.

+File: scm-5f2.info, Node: Makefile targets, Prev: Making scmlit, Up: GNU configure and make
- Typing `(e)' will invoke the editor with the file of interest.
- After editing, the modified file will be loaded.
+2.2.2 Makefile targets
+----------------------
+
+Each of the following four `make' targets creates an executable named
+`scm'. Each target takes its build options from a file with an `.opt'
+suffix. If that options file doesn't exist, making that target will
+create the file with the `-F' features: cautious, bignums, arrays,
+inexact, engineering-notation, and dynamic-linking. Once that `.opt'
+file exists, you can edit it to your taste and it will be preserved.
+
+`make scm4'
+ Produces a R4RS executable named `scm' lacking hygienic macros
+ (but with defmacro). The build options are taken from `scm4.opt'.
+ If build or the executable fails, try removing `dynamic-linking'
+ from `scm4.opt'.
+
+`make scm5'
+ R5RS; like `make scm4' but with `-F macro'. The build options are
+ taken from `scm5.opt'. If build or the executable fails, try
+ removing `dynamic-linking' from `scm5.opt'.
+
+`make dscm4'
+ Produces a R4RS executable named `udscm4', which it starts and
+ dumps to a low startup latency executable named `scm'. The build
+ options are taken from `udscm4.opt'.
+
+ If the build fails, then `build scm4' instead. If the dumped
+ executable fails to run, then send me a bug report (and use
+ `build scm4' until the problem with dump is corrected).
+
+`make dscm5'
+ Like `make dscm4' but with `-F macro'. The build options are
+ taken from `udscm5.opt'.
+
+ If the build fails, then `build scm5' instead. If the dumped
+ executable fails to run, then send me a bug report (and use
+ `build scm5' until the problem with dump is corrected).
+
+
+If the above builds fail because of `-F dynamic-linking', then (because
+they can't be dynamically linked) you will likely want to add some
+other features to the build's `.opt' file. See the `-F' build option
+in *note Build Options::.
+
+If dynamic-linking is working, then you will likely want to compile
+most of the modules as "DLL"s. The build options for compiling DLLs
+are in `dlls.opt'.
+
+`make x.so'
+ The `Xlib' module; *note SCM Language X Interface: (Xlibscm)Top.
+
+`make myturtle'
+ Creates a DLL named `turtlegr.so' which is a simple graphics API.
+
+`make wbscm.so'
+ The `wb' module; *note B-tree database implementation: (wb)Top.
+ Compiling this requires that wb source be in a peer directory to
+ scm.
+
+`make dlls'
+ Compiles all the distributed library modules, but not `wbscm.so'.
+ Many of the module compiles are recursively invoked in such a way
+ that failure of one (which could be due to a system library not
+ being installed) doesn't cause the top-level `make dlls' to fail.
+ If `make dlls' fails as a whole, it is time to submit a bug report
+ (*note Reporting Problems::).

+
+2.3.1 Invoking Build
+--------------------
+
+This section teaches how to use `build', a Scheme program for creating
+compilation scripts to produce SCM executables and library modules.
+The options accepted by `build' are documented in *note Build Options::.
+
+Use the _any_ method if you encounter problems with the other two
+methods (MS-DOS, Unix).
+
+MS-DOS
+ From the SCM source directory, type `build' followed by up to 9
+ command line arguments.
+
+Unix
+ From the SCM source directory, type `./build' followed by command
+ line arguments.
+
+_any_
+ From the SCM source directory, start `scm' or `scmlit' and type
+ `(load "build")'. Alternatively, start `scm' or `scmlit' with the
+ command line argument `-ilbuild'. This method will also work for
+ MS-DOS and Unix.
+
+ After loading various SLIB modules, the program will print:
+
+ type (b "build <command-line>") to build
+ type (b*) to enter build command loop
+
+ The `b*' procedure enters into a "build shell" where you can enter
+ commands (with or without the `build'). Blank lines are ignored.
+ To create a build script with all defaults type `build'.
+
+ If the build-shell encouters an error, you can reenter the
+ build-shell by typing `(b*)'. To exit scm type `(quit)'.
+
+
+Here is a transcript of an interactive (b*) build-shell.

+
+ "arrays"
+ Use if you want arrays, uniform-arrays and uniform-vectors.
+
+ "bignums"
+ Large precision integers.
+
+ "byte"
+ Treating strings as byte-vectors.
+
+ "byte-number"
+ Byte/number conversions
+
+ "careful-interrupt-masking"
+ Define this for extra checking of interrupt masking and some
+ simple checks for proper use of malloc and free. This is for
+ debugging C code in `sys.c', `eval.c', `repl.c' and makes the
+ interpreter several times slower than usual.
+
+ "cautious"
+ Normally, the number of arguments arguments to interpreted
+ closures (from LAMBDA) are checked if the function part of a
+ form is not a symbol or only the first time the form is
+ executed if the function part is a symbol. defining
+ `reckless' disables any checking. If you want to have SCM
+ always check the number of arguments to interpreted closures
+ define feature `cautious'.
+
+ "cheap-continuations"
+ If you only need straight stack continuations, executables
+ compile with this feature will run faster and use less
+ storage than not having it. Machines with unusual stacks
+ _need_ this. Also, if you incorporate new C code into scm
+ which uses VMS system services or library routines (which
+ need to unwind the stack in an ordrly manner) you may need to
+ use this feature.
+
+ "compiled-closure"
+ Use if you want to use compiled closures.
+
+ "curses"
+ For the "curses" screen management package.
+
+ "debug"
+ Turns on the features `cautious' and
+ `careful-interrupt-masking'; uses `-g' flags for debugging
+ SCM source code.
+
+ "differ"
+ Sequence comparison
+
+ "dont-memoize-locals"
+ SCM normally converts references to local variables to ILOCs,
+ which make programs run faster. If SCM is badly broken, try
+ using this option to disable the MEMOIZE_LOCALS feature.
+
+ "dump"
+ Convert a running scheme program into an executable file.
+ "dynamic-linking"
+ Be able to load compiled files while running.
+ "edit-line"
+ interface to the editline or GNU readline library.

+File: scm-5f2.info, Node: Saving Executable Images, Next: Installation, Prev: Building SCM, Up: Installing SCM
+
+2.4 Saving Executable Images
+============================
+
+In SCM, the ability to save running program images is called "dump"
+(*note Dump::). In order to make `dump' available to SCM, build with
+feature `dump'. `dump'ed executables are compatible with dynamic
+linking.
+
+Most of the code for "dump" is taken from `emacs-19.34/src/unex*.c'.
+No modifications to the emacs source code were required to use
+`unexelf.c'. Dump has not been ported to all platforms. If `unexec.c'
+or `unexelf.c' don't work for you, try using the appropriate `unex*.c'
+file from emacs.
+
+The `dscm4' and `dscm5' targets in the SCM `Makefile' save images from
+`udscm4' and `udscm5' executables respectively.
+
+"Address space layout randomization" interferes with `dump'. Here are
+the fixes for various operating-systems:
+
+Fedora-Core-1
+ Remove the `#' from the line `#SETARCH = setarch i386' in the
+ `Makefile'.
+
+Fedora-Core-3
+ `http://jamesthornton.com/writing/emacs-compile.html' [For FC3]
+ combreloc has become the default for recent GNU ld, which breaks
+ the unexec/undump on all versions of both Emacs and XEmacs...
+
+ Override by adding the following to `udscm5.opt':
+ `--linker-options="-z nocombreloc"'
+
+Linux Kernels later than 2.6.11
+`http://www.opensubscriber.com/message/emacs-devel@gnu.org/1007118.html'
+ mentions the "exec-shield" feature. Kernels later than 2.6.11
+ must do (as root):
+
+ echo 0 > /proc/sys/kernel/randomize_va_space
+
+ before dumping. `Makefile' has this `randomize_va_space' stuffing
+ scripted for targets `dscm4' and `dscm5'. You must either set
+ `randomize_va_space' to 0 or run as root to dump.
+
+OS-X 10.6
+`http://developer.apple.com/library/mac/#documentation/Darwin/Reference/Manpages/man1/dyld.1.html'
+ The dynamic linker uses the following environment variables. They
+ affect any program that uses the dynamic linker.
+
+ DYLD_NO_PIE
+
+ Causes dyld to not randomize the load addresses of images in a
+ process where the main executable was built position independent.
+ This can be helpful when trying to reproduce and debug a problem
+ in a PIE.

+=======================
+
+ -- Function: ed arg1 ...
+ The value of the environment variable `EDITOR' (or just `ed' if it
+ isn't defined) is invoked as a command with arguments ARG1 ....
+
+ -- Function: ed filename
+ If SCM is compiled under VMS `ed' will invoke the editor with a
+ single the single argument FILENAME.
+
+Gnu Emacs:
+ Editing of Scheme code is supported by emacs. Buffers holding
+ files ending in .scm are automatically put into scheme-mode.
+
+ If your Emacs can run a process in a buffer you can use the Emacs
+ command `M-x run-scheme' with SCM. Otherwise, use the emacs
+ command `M-x suspend-emacs'; or see "other systems" below.
+
+Epsilon (MS-DOS):
+ There is lisp (and scheme) mode available by use of the package
+ `LISP.E'. It offers several different indentation formats. With
+ this package, buffers holding files ending in `.L', `.LSP', `.S',
+ and `.SCM' (my modification) are automatically put into lisp-mode.
+
+ It is possible to run a process in a buffer under Epsilon. With
+ Epsilon 5.0 the command line options `-e512 -m0' are neccessary to
+ manage RAM properly. It has been reported that when compiling SCM
+ with Turbo C, you need to `#define NOSETBUF' for proper operation
+ in a process buffer with Epsilon 5.0.
+
+ One can also call out to an editor from SCM if RAM is at a
+ premium; See "under other systems" below.
+
+other systems:
+ Define the environment variable `EDITOR' to be the name of the
+ editing program you use. The SCM procedure `(ed arg1 ...)' will
+ invoke your editor and return to SCM when you exit the editor. The
+ following definition is convenient:
+
+ (define (e) (ed "work.scm") (load "work.scm"))
+
+ Typing `(e)' will invoke the editor with the file of interest.
+ After editing, the modified file will be loaded.

+Usage: ./configure [OPTION]...
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print configuration
+ -n, --no-create do not create output file
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]

- Version 1.2, November 2002 |
- |
- Copyright (C) 2000,2001,2002 Free Software Foundation, Inc. |
- 51 Franklin St, Fifth Floor, Boston, MA 02110-1301, USA |
- |
- Everyone is permitted to copy and distribute verbatim copies |
- of this license document, but changing it is not allowed. |
- |
- 0. PREAMBLE |
- |
- The purpose of this License is to make a manual, textbook, or other |
- functional and useful document "free" in the sense of freedom: to |
- assure everyone the effective freedom to copy and redistribute it, |
- with or without modifying it, either commercially or |
- noncommercially. Secondarily, this License preserves for the |
- author and publisher a way to get credit for their work, while not |
- being considered responsible for modifications made by others. |
- |
- This License is a kind of "copyleft", which means that derivative |
- works of the document must themselves be free in the same sense. |
- It complements the GNU General Public License, which is a copyleft |
- license designed for free software. |
- |
- We have designed this License in order to use it for manuals for |
- free software, because free software needs free documentation: a |
- free program should come with manuals providing the same freedoms |
- that the software does. But this License is not limited to |
- software manuals; it can be used for any textual work, regardless |
- of subject matter or whether it is published as a printed book. |
- We recommend this License principally for works whose purpose is |
- instruction or reference. |
- |
- 1. APPLICABILITY AND DEFINITIONS |
- |
- This License applies to any manual or other work, in any medium, |
- that contains a notice placed by the copyright holder saying it |
- can be distributed under the terms of this License. Such a notice |
- grants a world-wide, royalty-free license, unlimited in duration, |
- to use that work under the conditions stated herein. The |
- "Document", below, refers to any such manual or work. Any member |
- of the public is a licensee, and is addressed as "you". You |
- accept the license if you copy, modify or distribute the work in a |
- way requiring permission under copyright law. |
- |
- A "Modified Version" of the Document means any work containing the |
- Document or a portion of it, either copied verbatim, or with |
- modifications and/or translated into another language. |
- |
- A "Secondary Section" is a named appendix or a front-matter section |
- of the Document that deals exclusively with the relationship of the |
- publishers or authors of the Document to the Document's overall |
- subject (or to related matters) and contains nothing that could |
- fall directly within that overall subject. (Thus, if the Document |
- is in part a textbook of mathematics, a Secondary Section may not |
- explain any mathematics.) The relationship could be a matter of |
- historical connection with the subject or with related matters, or |
- of legal, commercial, philosophical, ethical or political position |
- regarding them. |
- |
- The "Invariant Sections" are certain Secondary Sections whose |
- titles are designated, as being those of Invariant Sections, in |
- the notice that says that the Document is released under this |
- License. If a section does not fit the above definition of |
- Secondary then it is not allowed to be designated as Invariant. |
- The Document may contain zero Invariant Sections. If the Document |
- does not identify any Invariant Sections then there are none. |
- |
- The "Cover Texts" are certain short passages of text that are |
- listed, as Front-Cover Texts or Back-Cover Texts, in the notice |
- that says that the Document is released under this License. A |
- Front-Cover Text may be at most 5 words, and a Back-Cover Text may |
- be at most 25 words. |
- |
- A "Transparent" copy of the Document means a machine-readable copy, |
- represented in a format whose specification is available to the |
- general public, that is suitable for revising the document |
- straightforwardly with generic text editors or (for images |
- composed of pixels) generic paint programs or (for drawings) some |
- widely available drawing editor, and that is suitable for input to |
- text formatters or for automatic translation to a variety of |
- formats suitable for input to text formatters. A copy made in an |
- otherwise Transparent file format whose markup, or absence of |
- markup, has been arranged to thwart or discourage subsequent |
- modification by readers is not Transparent. An image format is |
- not Transparent if used for any substantial amount of text. A |
- copy that is not "Transparent" is called "Opaque". |
- |
- Examples of suitable formats for Transparent copies include plain |
- ASCII without markup, Texinfo input format, LaTeX input format, |
- SGML or XML using a publicly available DTD, and |
- standard-conforming simple HTML, PostScript or PDF designed for |
- human modification. Examples of transparent image formats include |
- PNG, XCF and JPG. Opaque formats include proprietary formats that |
- can be read and edited only by proprietary word processors, SGML or |
- XML for which the DTD and/or processing tools are not generally |
- available, and the machine-generated HTML, PostScript or PDF |
- produced by some word processors for output purposes only. |
- |
- The "Title Page" means, for a printed book, the title page itself, |
- plus such following pages as are needed to hold, legibly, the |
- material this License requires to appear in the title page. For |
- works in formats which do not have any title page as such, "Title |
- Page" means the text near the most prominent appearance of the |
- work's title, preceding the beginning of the body of the text. |
- |
- A section "Entitled XYZ" means a named subunit of the Document |
- whose title either is precisely XYZ or contains XYZ in parentheses |
- following text that translates XYZ in another language. (Here XYZ |
- stands for a specific section name mentioned below, such as |
- "Acknowledgements", "Dedications", "Endorsements", or "History".) |
- To "Preserve the Title" of such a section when you modify the |
- Document means that it remains a section "Entitled XYZ" according |
- to this definition. |
- |
- The Document may include Warranty Disclaimers next to the notice |
- which states that this License applies to the Document. These |
- Warranty Disclaimers are considered to be included by reference in |
- this License, but only as regards disclaiming warranties: any other |
- implication that these Warranty Disclaimers may have is void and |
- has no effect on the meaning of this License. |
- |
- 2. VERBATIM COPYING |
- |
- You may copy and distribute the Document in any medium, either |
- commercially or noncommercially, provided that this License, the |
- copyright notices, and the license notice saying this License |
- applies to the Document are reproduced in all copies, and that you |
- add no other conditions whatsoever to those of this License. You |
- may not use technical measures to obstruct or control the reading |
- or further copying of the copies you make or distribute. However, |
- you may accept compensation in exchange for copies. If you |
- distribute a large enough number of copies you must also follow |
- the conditions in section 3. |
- |
- You may also lend copies, under the same conditions stated above, |
- and you may publicly display copies. |
- |
- 3. COPYING IN QUANTITY |
- |
- If you publish printed copies (or copies in media that commonly |
- have printed covers) of the Document, numbering more than 100, and |
- the Document's license notice requires Cover Texts, you must |
- enclose the copies in covers that carry, clearly and legibly, all |
- these Cover Texts: Front-Cover Texts on the front cover, and |
- Back-Cover Texts on the back cover. Both covers must also clearly |
- and legibly identify you as the publisher of these copies. The |
- front cover must present the full title with all words of the |
- title equally prominent and visible. You may add other material |
- on the covers in addition. Copying with changes limited to the |
- covers, as long as they preserve the title of the Document and |
- satisfy these conditions, can be treated as verbatim copying in |
- other respects. |
- |
- If the required texts for either cover are too voluminous to fit |
- legibly, you should put the first ones listed (as many as fit |
- reasonably) on the actual cover, and continue the rest onto |
- adjacent pages. |
- |
- If you publish or distribute Opaque copies of the Document |
- numbering more than 100, you must either include a |
- machine-readable Transparent copy along with each Opaque copy, or |
- state in or with each Opaque copy a computer-network location from |
- which the general network-using public has access to download |
- using public-standard network protocols a complete Transparent |
- copy of the Document, free of added material. If you use the |
- latter option, you must take reasonably prudent steps, when you |
- begin distribution of Opaque copies in quantity, to ensure that |
- this Transparent copy will remain thus accessible at the stated |
- location until at least one year after the last time you |
- distribute an Opaque copy (directly or through your agents or |
- retailers) of that edition to the public. |
- |
- It is requested, but not required, that you contact the authors of |
- the Document well before redistributing any large number of |
- copies, to give them a chance to provide you with an updated |
- version of the Document. |
- |
- 4. MODIFICATIONS |
- |
- You may copy and distribute a Modified Version of the Document |
- under the conditions of sections 2 and 3 above, provided that you |
- release the Modified Version under precisely this License, with |
- the Modified Version filling the role of the Document, thus |
- licensing distribution and modification of the Modified Version to |
- whoever possesses a copy of it. In addition, you must do these |
- things in the Modified Version: |
- |
- A. Use in the Title Page (and on the covers, if any) a title |
- distinct from that of the Document, and from those of |
- previous versions (which should, if there were any, be listed |
- in the History section of the Document). You may use the |
- same title as a previous version if the original publisher of |
- that version gives permission. |
- |
- B. List on the Title Page, as authors, one or more persons or |
- entities responsible for authorship of the modifications in |
- the Modified Version, together with at least five of the |
- principal authors of the Document (all of its principal |
- authors, if it has fewer than five), unless they release you |
- from this requirement. |
- |
- C. State on the Title page the name of the publisher of the |
- Modified Version, as the publisher. |
- |
- D. Preserve all the copyright notices of the Document. |
- |
- E. Add an appropriate copyright notice for your modifications |
- adjacent to the other copyright notices. |
- |
- F. Include, immediately after the copyright notices, a license |
- notice giving the public permission to use the Modified |
- Version under the terms of this License, in the form shown in |
- the Addendum below. |
- |
- G. Preserve in that license notice the full lists of Invariant |
- Sections and required Cover Texts given in the Document's |
- license notice. |
- |
- H. Include an unaltered copy of this License. |
- |
- I. Preserve the section Entitled "History", Preserve its Title, |
- and add to it an item stating at least the title, year, new |
- authors, and publisher of the Modified Version as given on |
- the Title Page. If there is no section Entitled "History" in |
- the Document, create one stating the title, year, authors, |
- and publisher of the Document as given on its Title Page, |
- then add an item describing the Modified Version as stated in |
- the previous sentence. |
- |
- J. Preserve the network location, if any, given in the Document |
- for public access to a Transparent copy of the Document, and |
- likewise the network locations given in the Document for |
- previous versions it was based on. These may be placed in |
- the "History" section. You may omit a network location for a |
- work that was published at least four years before the |
- Document itself, or if the original publisher of the version |
- it refers to gives permission. |
- |
- K. For any section Entitled "Acknowledgements" or "Dedications", |
- Preserve the Title of the section, and preserve in the |
- section all the substance and tone of each of the contributor |
- acknowledgements and/or dedications given therein. |
- |
- L. Preserve all the Invariant Sections of the Document, |
- unaltered in their text and in their titles. Section numbers |
- or the equivalent are not considered part of the section |
- titles. |
- |
- M. Delete any section Entitled "Endorsements". Such a section |
- may not be included in the Modified Version. |
- |
- N. Do not retitle any existing section to be Entitled |
- "Endorsements" or to conflict in title with any Invariant |
- Section. |
- |
- O. Preserve any Warranty Disclaimers. |
- |
- If the Modified Version includes new front-matter sections or |
- appendices that qualify as Secondary Sections and contain no |
- material copied from the Document, you may at your option |
- designate some or all of these sections as invariant. To do this, |
- add their titles to the list of Invariant Sections in the Modified |
- Version's license notice. These titles must be distinct from any |
- other section titles. |
- |
- You may add a section Entitled "Endorsements", provided it contains |
- nothing but endorsements of your Modified Version by various |
- parties--for example, statements of peer review or that the text |
- has been approved by an organization as the authoritative |
- definition of a standard. |
- |
- You may add a passage of up to five words as a Front-Cover Text, |
- and a passage of up to 25 words as a Back-Cover Text, to the end |
- of the list of Cover Texts in the Modified Version. Only one |
- passage of Front-Cover Text and one of Back-Cover Text may be |
- added by (or through arrangements made by) any one entity. If the |
- Document already includes a cover text for the same cover, |
- previously added by you or by arrangement made by the same entity |
- you are acting on behalf of, you may not add another; but you may |
- replace the old one, on explicit permission from the previous |
- publisher that added the old one. |
- |
- The author(s) and publisher(s) of the Document do not by this |
- License give permission to use their names for publicity for or to |
- assert or imply endorsement of any Modified Version. |
- |
- 5. COMBINING DOCUMENTS |
- |
- You may combine the Document with other documents released under |
- this License, under the terms defined in section 4 above for |
- modified versions, provided that you include in the combination |
- all of the Invariant Sections of all of the original documents, |
- unmodified, and list them all as Invariant Sections of your |
- combined work in its license notice, and that you preserve all |
- their Warranty Disclaimers. |
- |
- The combined work need only contain one copy of this License, and |
- multiple identical Invariant Sections may be replaced with a single |
- copy. If there are multiple Invariant Sections with the same name |
- but different contents, make the title of each such section unique |
- by adding at the end of it, in parentheses, the name of the |
- original author or publisher of that section if known, or else a |
- unique number. Make the same adjustment to the section titles in |
- the list of Invariant Sections in the license notice of the |
- combined work. |
- |
- In the combination, you must combine any sections Entitled |
- "History" in the various original documents, forming one section |
- Entitled "History"; likewise combine any sections Entitled |
- "Acknowledgements", and any sections Entitled "Dedications". You |
- must delete all sections Entitled "Endorsements." |
- |
- 6. COLLECTIONS OF DOCUMENTS |
- |
- You may make a collection consisting of the Document and other |
- documents released under this License, and replace the individual |
- copies of this License in the various documents with a single copy |
- that is included in the collection, provided that you follow the |
- rules of this License for verbatim copying of each of the |
- documents in all other respects. |
- |
- You may extract a single document from such a collection, and |
- distribute it individually under this License, provided you insert |
- a copy of this License into the extracted document, and follow |
- this License in all other respects regarding verbatim copying of |
- that document. |
- |
- 7. AGGREGATION WITH INDEPENDENT WORKS |
- |
- A compilation of the Document or its derivatives with other |
- separate and independent documents or works, in or on a volume of |
- a storage or distribution medium, is called an "aggregate" if the |
- copyright resulting from the compilation is not used to limit the |
- legal rights of the compilation's users beyond what the individual |
- works permit. When the Document is included in an aggregate, this |
- License does not apply to the other works in the aggregate which |
- are not themselves derivative works of the Document. |
- |
- If the Cover Text requirement of section 3 is applicable to these |
- copies of the Document, then if the Document is less than one half |
- of the entire aggregate, the Document's Cover Texts may be placed |
- on covers that bracket the Document within the aggregate, or the |
- electronic equivalent of covers if the Document is in electronic |
- form. Otherwise they must appear on printed covers that bracket |
- the whole aggregate. |

- |
- Translation is considered a kind of modification, so you may |
- distribute translations of the Document under the terms of section |
- 4. Replacing Invariant Sections with translations requires special |
- permission from their copyright holders, but you may include |
- translations of some or all Invariant Sections in addition to the |
- original versions of these Invariant Sections. You may include a |
- translation of this License, and all the license notices in the |
- Document, and any Warranty Disclaimers, provided that you also |
- include the original English version of this License and the |
- original versions of those notices and disclaimers. In case of a |
- disagreement between the translation and the original version of |
- this License or a notice or disclaimer, the original version will |
- prevail. |
- |
- If a section in the Document is Entitled "Acknowledgements", |
- "Dedications", or "History", the requirement (section 4) to |
- Preserve its Title (section 1) will typically require changing the |
- actual title. |
- |
- 9. TERMINATION |
- |
- You may not copy, modify, sublicense, or distribute the Document |
- except as expressly provided for under this License. Any other |
- attempt to copy, modify, sublicense or distribute the Document is |
- void, and will automatically terminate your rights under this |
- License. However, parties who have received copies, or rights, |
- from you under this License will not have their licenses |
- terminated so long as such parties remain in full compliance. |
- |
- 10. FUTURE REVISIONS OF THIS LICENSE |
- |
- The Free Software Foundation may publish new, revised versions of |
- the GNU Free Documentation License from time to time. Such new |
- versions will be similar in spirit to the present version, but may |
- differ in detail to address new problems or concerns. See |
- `http://www.gnu.org/copyleft/'. |
- |
- Each version of the License is given a distinguishing version |
- number. If the Document specifies that a particular numbered |
- version of this License "or any later version" applies to it, you |
- have the option of following the terms and conditions either of |
- that specified version or of any later version that has been |
- published (not as a draft) by the Free Software Foundation. If |
- the Document does not specify a version number of this License, |
- you may choose any version ever published (not as a draft) by the |
- Free Software Foundation. |
- |
-ADDENDUM: How to use this License for your documents |
-==================================================== |
- |
-To use this License in a document you have written, include a copy of |
-the License in the document and put the following copyright and license |
-notices just after the title page: |
- |
- Copyright (C) YEAR YOUR NAME. |
- Permission is granted to copy, distribute and/or modify this document |
- under the terms of the GNU Free Documentation License, Version 1.2 |
- or any later version published by the Free Software Foundation; |
- with no Invariant Sections, no Front-Cover Texts, and no Back-Cover |
- Texts. A copy of the license is included in the section entitled ``GNU
- Free Documentation License''. |
- |
-If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts, |
-replace the "with...Texts." line with this: |
- |
- with the Invariant Sections being LIST THEIR TITLES, with |
- the Front-Cover Texts being LIST, and with the Back-Cover Texts |
- being LIST. |
- |
-If you have Invariant Sections without Cover Texts, or some other |
-combination of the three, merge those two alternatives to suit the |
-situation. |
- |
-If your document contains nontrivial examples of program code, we |
-recommend releasing these examples in parallel under your choice of |

+1.3.3 GNU Free Documentation License
+------------------------------------
+
+ Version 1.3, 3 November 2008
+
+ Copyright (C) 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc.
+ `http://fsf.org/'
+
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ 0. PREAMBLE
+
+ The purpose of this License is to make a manual, textbook, or other
+ functional and useful document "free" in the sense of freedom: to
+ assure everyone the effective freedom to copy and redistribute it,
+ with or without modifying it, either commercially or
+ noncommercially. Secondarily, this License preserves for the
+ author and publisher a way to get credit for their work, while not
+ being considered responsible for modifications made by others.
+
+ This License is a kind of "copyleft", which means that derivative
+ works of the document must themselves be free in the same sense.
+ It complements the GNU General Public License, which is a copyleft
+ license designed for free software.
+
+ We have designed this License in order to use it for manuals for
+ free software, because free software needs free documentation: a
+ free program should come with manuals providing the same freedoms
+ that the software does. But this License is not limited to
+ software manuals; it can be used for any textual work, regardless
+ of subject matter or whether it is published as a printed book.
+ We recommend this License principally for works whose purpose is
+ instruction or reference.
+
+ 1. APPLICABILITY AND DEFINITIONS
+
+ This License applies to any manual or other work, in any medium,
+ that contains a notice placed by the copyright holder saying it
+ can be distributed under the terms of this License. Such a notice
+ grants a world-wide, royalty-free license, unlimited in duration,
+ to use that work under the conditions stated herein. The
+ "Document", below, refers to any such manual or work. Any member
+ of the public is a licensee, and is addressed as "you". You
+ accept the license if you copy, modify or distribute the work in a
+ way requiring permission under copyright law.
+
+ A "Modified Version" of the Document means any work containing the
+ Document or a portion of it, either copied verbatim, or with
+ modifications and/or translated into another language.
+
+ A "Secondary Section" is a named appendix or a front-matter section
+ of the Document that deals exclusively with the relationship of the
+ publishers or authors of the Document to the Document's overall
+ subject (or to related matters) and contains nothing that could
+ fall directly within that overall subject. (Thus, if the Document
+ is in part a textbook of mathematics, a Secondary Section may not
+ explain any mathematics.) The relationship could be a matter of
+ historical connection with the subject or with related matters, or
+ of legal, commercial, philosophical, ethical or political position
+ regarding them.
+
+ The "Invariant Sections" are certain Secondary Sections whose
+ titles are designated, as being those of Invariant Sections, in
+ the notice that says that the Document is released under this
+ License. If a section does not fit the above definition of
+ Secondary then it is not allowed to be designated as Invariant.
+ The Document may contain zero Invariant Sections. If the Document
+ does not identify any Invariant Sections then there are none.
+
+ The "Cover Texts" are certain short passages of text that are
+ listed, as Front-Cover Texts or Back-Cover Texts, in the notice
+ that says that the Document is released under this License. A
+ Front-Cover Text may be at most 5 words, and a Back-Cover Text may
+ be at most 25 words.
+
+ A "Transparent" copy of the Document means a machine-readable copy,
+ represented in a format whose specification is available to the
+ general public, that is suitable for revising the document
+ straightforwardly with generic text editors or (for images
+ composed of pixels) generic paint programs or (for drawings) some
+ widely available drawing editor, and that is suitable for input to
+ text formatters or for automatic translation to a variety of
+ formats suitable for input to text formatters. A copy made in an
+ otherwise Transparent file format whose markup, or absence of
+ markup, has been arranged to thwart or discourage subsequent
+ modification by readers is not Transparent. An image format is
+ not Transparent if used for any substantial amount of text. A
+ copy that is not "Transparent" is called "Opaque".
+
+ Examples of suitable formats for Transparent copies include plain
+ ASCII without markup, Texinfo input format, LaTeX input format,
+ SGML or XML using a publicly available DTD, and
+ standard-conforming simple HTML, PostScript or PDF designed for
+ human modification. Examples of transparent image formats include
+ PNG, XCF and JPG. Opaque formats include proprietary formats that
+ can be read and edited only by proprietary word processors, SGML or
+ XML for which the DTD and/or processing tools are not generally
+ available, and the machine-generated HTML, PostScript or PDF
+ produced by some word processors for output purposes only.
+
+ The "Title Page" means, for a printed book, the title page itself,
+ plus such following pages as are needed to hold, legibly, the
+ material this License requires to appear in the title page. For
+ works in formats which do not have any title page as such, "Title
+ Page" means the text near the most prominent appearance of the
+ work's title, preceding the beginning of the body of the text.
+
+ The "publisher" means any person or entity that distributes copies
+ of the Document to the public.
+
+ A section "Entitled XYZ" means a named subunit of the Document
+ whose title either is precisely XYZ or contains XYZ in parentheses
+ following text that translates XYZ in another language. (Here XYZ
+ stands for a specific section name mentioned below, such as
+ "Acknowledgements", "Dedications", "Endorsements", or "History".)
+ To "Preserve the Title" of such a section when you modify the
+ Document means that it remains a section "Entitled XYZ" according
+ to this definition.
+
+ The Document may include Warranty Disclaimers next to the notice
+ which states that this License applies to the Document. These
+ Warranty Disclaimers are considered to be included by reference in
+ this License, but only as regards disclaiming warranties: any other
+ implication that these Warranty Disclaimers may have is void and
+ has no effect on the meaning of this License.
+
+ 2. VERBATIM COPYING
+
+ You may copy and distribute the Document in any medium, either
+ commercially or noncommercially, provided that this License, the
+ copyright notices, and the license notice saying this License
+ applies to the Document are reproduced in all copies, and that you
+ add no other conditions whatsoever to those of this License. You
+ may not use technical measures to obstruct or control the reading
+ or further copying of the copies you make or distribute. However,
+ you may accept compensation in exchange for copies. If you
+ distribute a large enough number of copies you must also follow
+ the conditions in section 3.
+
+ You may also lend copies, under the same conditions stated above,
+ and you may publicly display copies.
+
+ 3. COPYING IN QUANTITY
+
+ If you publish printed copies (or copies in media that commonly
+ have printed covers) of the Document, numbering more than 100, and
+ the Document's license notice requires Cover Texts, you must
+ enclose the copies in covers that carry, clearly and legibly, all
+ these Cover Texts: Front-Cover Texts on the front cover, and
+ Back-Cover Texts on the back cover. Both covers must also clearly
+ and legibly identify you as the publisher of these copies. The
+ front cover must present the full title with all words of the
+ title equally prominent and visible. You may add other material
+ on the covers in addition. Copying with changes limited to the
+ covers, as long as they preserve the title of the Document and
+ satisfy these conditions, can be treated as verbatim copying in
+ other respects.
+
+ If the required texts for either cover are too voluminous to fit
+ legibly, you should put the first ones listed (as many as fit
+ reasonably) on the actual cover, and continue the rest onto
+ adjacent pages.
+
+ If you publish or distribute Opaque copies of the Document
+ numbering more than 100, you must either include a
+ machine-readable Transparent copy along with each Opaque copy, or
+ state in or with each Opaque copy a computer-network location from
+ which the general network-using public has access to download
+ using public-standard network protocols a complete Transparent
+ copy of the Document, free of added material. If you use the
+ latter option, you must take reasonably prudent steps, when you
+ begin distribution of Opaque copies in quantity, to ensure that
+ this Transparent copy will remain thus accessible at the stated
+ location until at least one year after the last time you
+ distribute an Opaque copy (directly or through your agents or
+ retailers) of that edition to the public.
+
+ It is requested, but not required, that you contact the authors of
+ the Document well before redistributing any large number of
+ copies, to give them a chance to provide you with an updated
+ version of the Document.
+
+ 4. MODIFICATIONS
+
+ You may copy and distribute a Modified Version of the Document
+ under the conditions of sections 2 and 3 above, provided that you
+ release the Modified Version under precisely this License, with
+ the Modified Version filling the role of the Document, thus
+ licensing distribution and modification of the Modified Version to
+ whoever possesses a copy of it. In addition, you must do these
+ things in the Modified Version:
+
+ A. Use in the Title Page (and on the covers, if any) a title
+ distinct from that of the Document, and from those of
+ previous versions (which should, if there were any, be listed
+ in the History section of the Document). You may use the
+ same title as a previous version if the original publisher of
+ that version gives permission.
+
+ B. List on the Title Page, as authors, one or more persons or
+ entities responsible for authorship of the modifications in
+ the Modified Version, together with at least five of the
+ principal authors of the Document (all of its principal
+ authors, if it has fewer than five), unless they release you
+ from this requirement.
+
+ C. State on the Title page the name of the publisher of the
+ Modified Version, as the publisher.
+
+ D. Preserve all the copyright notices of the Document.
+
+ E. Add an appropriate copyright notice for your modifications
+ adjacent to the other copyright notices.
+
+ F. Include, immediately after the copyright notices, a license
+ notice giving the public permission to use the Modified
+ Version under the terms of this License, in the form shown in
+ the Addendum below.
+
+ G. Preserve in that license notice the full lists of Invariant
+ Sections and required Cover Texts given in the Document's
+ license notice.
+
+ H. Include an unaltered copy of this License.
+
+ I. Preserve the section Entitled "History", Preserve its Title,
+ and add to it an item stating at least the title, year, new
+ authors, and publisher of the Modified Version as given on
+ the Title Page. If there is no section Entitled "History" in
+ the Document, create one stating the title, year, authors,
+ and publisher of the Document as given on its Title Page,
+ then add an item describing the Modified Version as stated in
+ the previous sentence.
+
+ J. Preserve the network location, if any, given in the Document
+ for public access to a Transparent copy of the Document, and
+ likewise the network locations given in the Document for
+ previous versions it was based on. These may be placed in
+ the "History" section. You may omit a network location for a
+ work that was published at least four years before the
+ Document itself, or if the original publisher of the version
+ it refers to gives permission.
+
+ K. For any section Entitled "Acknowledgements" or "Dedications",
+ Preserve the Title of the section, and preserve in the
+ section all the substance and tone of each of the contributor
+ acknowledgements and/or dedications given therein.
+
+ L. Preserve all the Invariant Sections of the Document,
+ unaltered in their text and in their titles. Section numbers
+ or the equivalent are not considered part of the section
+ titles.
+
+ M. Delete any section Entitled "Endorsements". Such a section
+ may not be included in the Modified Version.
+
+ N. Do not retitle any existing section to be Entitled
+ "Endorsements" or to conflict in title with any Invariant
+ Section.
+
+ O. Preserve any Warranty Disclaimers.
+
+ If the Modified Version includes new front-matter sections or
+ appendices that qualify as Secondary Sections and contain no
+ material copied from the Document, you may at your option
+ designate some or all of these sections as invariant. To do this,
+ add their titles to the list of Invariant Sections in the Modified
+ Version's license notice. These titles must be distinct from any
+ other section titles.
+
+ You may add a section Entitled "Endorsements", provided it contains
+ nothing but endorsements of your Modified Version by various
+ parties--for example, statements of peer review or that the text
+ has been approved by an organization as the authoritative
+ definition of a standard.
+
+ You may add a passage of up to five words as a Front-Cover Text,
+ and a passage of up to 25 words as a Back-Cover Text, to the end
+ of the list of Cover Texts in the Modified Version. Only one
+ passage of Front-Cover Text and one of Back-Cover Text may be
+ added by (or through arrangements made by) any one entity. If the
+ Document already includes a cover text for the same cover,
+ previously added by you or by arrangement made by the same entity
+ you are acting on behalf of, you may not add another; but you may
+ replace the old one, on explicit permission from the previous
+ publisher that added the old one.
+
+ The author(s) and publisher(s) of the Document do not by this
+ License give permission to use their names for publicity for or to
+ assert or imply endorsement of any Modified Version.
+
+ 5. COMBINING DOCUMENTS
+
+ You may combine the Document with other documents released under
+ this License, under the terms defined in section 4 above for
+ modified versions, provided that you include in the combination
+ all of the Invariant Sections of all of the original documents,
+ unmodified, and list them all as Invariant Sections of your
+ combined work in its license notice, and that you preserve all
+ their Warranty Disclaimers.
+
+ The combined work need only contain one copy of this License, and
+ multiple identical Invariant Sections may be replaced with a single
+ copy. If there are multiple Invariant Sections with the same name
+ but different contents, make the title of each such section unique
+ by adding at the end of it, in parentheses, the name of the
+ original author or publisher of that section if known, or else a
+ unique number. Make the same adjustment to the section titles in
+ the list of Invariant Sections in the license notice of the
+ combined work.
+
+ In the combination, you must combine any sections Entitled
+ "History" in the various original documents, forming one section
+ Entitled "History"; likewise combine any sections Entitled
+ "Acknowledgements", and any sections Entitled "Dedications". You
+ must delete all sections Entitled "Endorsements."
+
+ 6. COLLECTIONS OF DOCUMENTS
+
+ You may make a collection consisting of the Document and other
+ documents released under this License, and replace the individual
+ copies of this License in the various documents with a single copy
+ that is included in the collection, provided that you follow the
+ rules of this License for verbatim copying of each of the
+ documents in all other respects.
+
+ You may extract a single document from such a collection, and
+ distribute it individually under this License, provided you insert
+ a copy of this License into the extracted document, and follow
+ this License in all other respects regarding verbatim copying of
+ that document.
+
+ 7. AGGREGATION WITH INDEPENDENT WORKS
+
+ A compilation of the Document or its derivatives with other
+ separate and independent documents or works, in or on a volume of
+ a storage or distribution medium, is called an "aggregate" if the
+ copyright resulting from the compilation is not used to limit the
+ legal rights of the compilation's users beyond what the individual
+ works permit. When the Document is included in an aggregate, this
+ License does not apply to the other works in the aggregate which
+ are not themselves derivative works of the Document.
+
+ If the Cover Text requirement of section 3 is applicable to these
+ copies of the Document, then if the Document is less than one half
+ of the entire aggregate, the Document's Cover Texts may be placed
+ on covers that bracket the Document within the aggregate, or the
+ electronic equivalent of covers if the Document is in electronic
+ form. Otherwise they must appear on printed covers that bracket
+ the whole aggregate.
+
+ 8. TRANSLATION
+
+ Translation is considered a kind of modification, so you may
+ distribute translations of the Document under the terms of section
+ 4. Replacing Invariant Sections with translations requires special
+ permission from their copyright holders, but you may include
+ translations of some or all Invariant Sections in addition to the
+ original versions of these Invariant Sections. You may include a
+ translation of this License, and all the license notices in the
+ Document, and any Warranty Disclaimers, provided that you also
+ include the original English version of this License and the
+ original versions of those notices and disclaimers. In case of a
+ disagreement between the translation and the original version of
+ this License or a notice or disclaimer, the original version will
+ prevail.
+
+ If a section in the Document is Entitled "Acknowledgements",
+ "Dedications", or "History", the requirement (section 4) to
+ Preserve its Title (section 1) will typically require changing the
+ actual title.
+
+ 9. TERMINATION
+
+ You may not copy, modify, sublicense, or distribute the Document
+ except as expressly provided under this License. Any attempt
+ otherwise to copy, modify, sublicense, or distribute it is void,
+ and will automatically terminate your rights under this License.
+
+ However, if you cease all violation of this License, then your
+ license from a particular copyright holder is reinstated (a)
+ provisionally, unless and until the copyright holder explicitly
+ and finally terminates your license, and (b) permanently, if the
+ copyright holder fails to notify you of the violation by some
+ reasonable means prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+ reinstated permanently if the copyright holder notifies you of the
+ violation by some reasonable means, this is the first time you have
+ received notice of violation of this License (for any work) from
+ that copyright holder, and you cure the violation prior to 30 days
+ after your receipt of the notice.
+
+ Termination of your rights under this section does not terminate
+ the licenses of parties who have received copies or rights from
+ you under this License. If your rights have been terminated and
+ not permanently reinstated, receipt of a copy of some or all of
+ the same material does not give you any rights to use it.
+
+ 10. FUTURE REVISIONS OF THIS LICENSE
+
+ The Free Software Foundation may publish new, revised versions of
+ the GNU Free Documentation License from time to time. Such new
+ versions will be similar in spirit to the present version, but may
+ differ in detail to address new problems or concerns. See
+ `http://www.gnu.org/copyleft/'.
+
+ Each version of the License is given a distinguishing version
+ number. If the Document specifies that a particular numbered
+ version of this License "or any later version" applies to it, you
+ have the option of following the terms and conditions either of
+ that specified version or of any later version that has been
+ published (not as a draft) by the Free Software Foundation. If
+ the Document does not specify a version number of this License,
+ you may choose any version ever published (not as a draft) by the
+ Free Software Foundation. If the Document specifies that a proxy
+ can decide which future versions of this License can be used, that
+ proxy's public statement of acceptance of a version permanently
+ authorizes you to choose that version for the Document.
+
+ 11. RELICENSING
+
+ "Massive Multiauthor Collaboration Site" (or "MMC Site") means any
+ World Wide Web server that publishes copyrightable works and also
+ provides prominent facilities for anybody to edit those works. A
+ public wiki that anybody can edit is an example of such a server.
+ A "Massive Multiauthor Collaboration" (or "MMC") contained in the
+ site means any set of copyrightable works thus published on the MMC
+ site.
+
+ "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0
+ license published by Creative Commons Corporation, a not-for-profit
+ corporation with a principal place of business in San Francisco,
+ California, as well as future copyleft versions of that license
+ published by that same organization.
+
+ "Incorporate" means to publish or republish a Document, in whole or
+ in part, as part of another Document.
+
+ An MMC is "eligible for relicensing" if it is licensed under this
+ License, and if all works that were first published under this
+ License somewhere other than this MMC, and subsequently
+ incorporated in whole or in part into the MMC, (1) had no cover
+ texts or invariant sections, and (2) were thus incorporated prior
+ to November 1, 2008.
+
+ The operator of an MMC Site may republish an MMC contained in the
+ site under CC-BY-SA on the same site at any time before August 1,
+ 2009, provided the MMC is eligible for relicensing.
+
+
+ADDENDUM: How to use this License for your documents
+====================================================
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and license
+notices just after the title page:
+
+ Copyright (C) YEAR YOUR NAME.
+ Permission is granted to copy, distribute and/or modify this document
+ under the terms of the GNU Free Documentation License, Version 1.3
+ or any later version published by the Free Software Foundation;
+ with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
+ Texts. A copy of the license is included in the section entitled ``GNU
+ Free Documentation License''.
+
+If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
+replace the "with...Texts." line with this:
+
+ with the Invariant Sections being LIST THEIR TITLES, with
+ the Front-Cover Texts being LIST, and with the Back-Cover Texts
+ being LIST.
+
+If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of
+free software license, such as the GNU General Public License, to
+permit their use in free software.

+2.1 Distributions |
+================= |
-The SCM distribution has "Makefile" which contains rules for making
-"scmlit", a "bare-bones" version of SCM sufficient for running `build'.
-`build' is used to compile (or create scripts to compile) full
-featured versions (*note Building SCM::).
+The SCM homepage contains links to precompiled binaries and source |
+distributions. |
-Makefiles are not portable to the majority of platforms. If `Makefile'
-works for you, good; If not, I don't want to hear about it. If you
-need to compile SCM without build, there are several ways to proceed:
+Downloads and instructions for installing the precompiled binaries are |

+2.2 GNU configure and make |
+========================== |
+ |
+`scm/configure' and `slib/configure' are Shell scripts which create the |
+files `scm/config.status' and `slib/config.status' on Unix and MinGW |
+systems. |
+ |
+The `config.status' files are used (included) by the Makefile to |
+control where the packages will be installed by `make install'. With |
+GNU shell (bash) and utilities, the following commands should build and |
+install SCM and SLIB: |
+ |
+ bash$ (cd slib; ./configure --prefix=/usr/local/) |
+ bash$ (cd scm |
+ > ./configure --prefix=/usr/local/ |
+ > make scmlit |
+ > sudo make all |
+ > sudo make install) |
+ bash$ (cd slib; sudo make install) |
+ |
+If the install commands worked, skip to *note Testing::. |
+ |
+If `configure' doesn't work on your system, make `scm/config.status' |
+and `slib/config.status' be empty files. |
+ |
+For additional help on using the `configure' script, run |
+`./configure --help'. |
+ |
+`make all' will attempt to create a dumped executable (*note Saving |
+Executable Images::), which has very small startup latency. If that |
+fails, it will try to compile an ordinary `scm' executable. |
+ |
+Note that the compilation output may contain error messages; be |
+concerned only if the `make install' transcripts contain errors. |
+ |
+`sudo' runs the command after it as user "root". On recent GNU/Linux |
+systems, dumping requires that `make all' be run as user root; hence |
+the use of `sudo'. |
+ |
+`make install' requires root privileges if you are installing to |
+standard Unix locations as specified to (or defaulted by) |
+`./configure'. Note that this is independent of whether you did |
+`sudo make all' or `make all'. |

+2.2.1 Making scmlit |
+------------------- |
+ |
+The SCM distribution `Makefile' contains rules for making "scmlit", a |
+"bare-bones" version of SCM sufficient for running `build'. `build' is |
+a Scheme program used to compile (or create scripts to compile) full |
+featured versions of SCM (*note Building SCM::). To create scmlit, run |
+`make scmlit' in the `scm/' directory. |
+ |
+Makefiles are not portable to the majority of platforms. If you need |
+to compile SCM without `scmlit', there are several ways to proceed: |
- * Use the build (http://swiss.csail.mit.edu/~jaffer/buildscm.html)
+ * Use the build (http://people.csail.mit.edu/jaffer/buildscm.html)

-========
-
-[SLIB] is a portable Scheme library meant to provide compatibility and
-utility functions for all standard Scheme implementations. Although
-SLIB is not _neccessary_ to run SCM, I strongly suggest you obtain and
-install it. Bug reports about running SCM without SLIB have very low
-priority. SLIB is available from the same sites as SCM:
+Finding SLIB |
+------------ |
- * swiss.csail.mit.edu:/pub/scm/slib-3b1.tar.gz |
+If you didn't create scmlit using `make scmlit', then you must create a |
+file named `scm/require.scm'. For most installations, |
+`scm/require.scm' can just be copied from `scm/requires.scm', which is |
+part of the SCM distribution. |
- * ftp.gnu.org:/pub/gnu/jacal/slib-3b1.tar.gz |

-an appropriate directory for your system; both `tar' and `unzip' will |
-create the directory `slib'.

+(this is the same directory as where the file `Init5f1.scm' is). |
+`require.scm' should have the contents: |
(define (library-vicinity) "/usr/local/lib/slib/")
where the pathname string `/usr/local/lib/slib/' is to be replaced by
-the pathname into which you installed SLIB. Absolute pathnames are
-recommended here; if you use a relative pathname, SLIB can get confused
-when the working directory is changed (*note chmod: I/O-Extensions.).
-The way to specify a relative pathname is to append it to the
-implementation-vicinity, which is absolute:
+the pathname into which you unzipped (or installed) SLIB. |
+ |
+Alternatively, you can set the (shell) environment variable |
+`SCHEME_LIBRARY_PATH' to the pathname of the SLIB directory (*note |
+SCHEME_LIBRARY_PATH: SCM Variables.). If set, this environment |
+variable overrides `scm/require.scm'. |
+ |
+Absolute pathnames are recommended here; if you use a relative |
+pathname, SLIB can get confused when the working directory is changed |

+2.2.2 Makefile targets |
+---------------------- |
+ |
+Each of the following four `make' targets creates an executable named |
+`scm'. Each target takes its build options from a file with an `.opt' |
+suffix. If that options file doesn't exist, making that target will |
+create the file with the `-F' features: cautious, bignums, arrays, |
+inexact, engineering-notation, and dynamic-linking. Once that `.opt' |
+file exists, you can edit it to your taste and it will be preserved. |
+ |
+`make scm4' |
+ Produces a R4RS executable named `scm' lacking hygienic macros |
+ (but with defmacro). The build options are taken from `scm4.opt'. |
+ If build or the executable fails, try removing `dynamic-linking' |
+ from `scm4.opt'. |
+ |
+`make scm5' |
+ R5RS; like `make scm4' but with `-F macro'. The build options are |
+ taken from `scm5.opt'. If build or the executable fails, try |
+ removing `dynamic-linking' from `scm5.opt'. |
+ |
+`make dscm4' |
+ Produces a R4RS executable named `udscm4', which it starts and |
+ dumps to a low startup latency executable named `scm'. The build |
+ options are taken from `udscm4.opt'. |
+ |
+ If the build fails, then `build scm4' instead. If the dumped |
+ executable fails to run, then send me a bug report (and use |
+ `build scm4' until the problem with dump is corrected). |
+ |
+`make dscm5' |
+ Like `make dscm4' but with `-F macro'. The build options are |
+ taken from `udscm5.opt'. |
+ |
+ If the build fails, then `build scm5' instead. If the dumped |
+ executable fails to run, then send me a bug report (and use |
+ `build scm5' until the problem with dump is corrected). |
+ |
+ |
+If the above builds fail because of `-F dynamic-linking', then (because |
+they can't be dynamically linked) you will likely want to add some |
+other features to the build's `.opt' file. See the `-F' build option |
+in *note Build Options::. |
+ |
+If dynamic-linking is working, then you will likely want to compile |
+most of the modules as "DLL"s. The build options for compiling DLLs |
+are in `dlls.opt'. |
+ |
+`make x.so' |
+ The `Xlib' module; *note SCM Language X Interface: (Xlibscm)Top. |
+ |
+`make myturtle' |
+ Creates a DLL named `turtlegr.so' which is a simple graphics API. |
+ |
+`make wbscm.so' |
+ The `wb' module; *note B-tree database implementation: (wb)Top. |
+ Compiling this requires that wb source be in a peer directory to |
+ scm. |
+ |
+`make dlls' |
+ Compiles all the distributed library modules, but not `wbscm.so'. |
+ Many of the module compiles are recursively invoked in such a way |
+ that failure of one (which could be due to a system library not |
+ being installed) doesn't cause the top-level `make dlls' to fail. |
+ If `make dlls' fails as a whole, it is time to submit a bug report |
+ (*note Reporting Problems::). |

-2.4 Installing Dynamic Linking
-==============================
-
-Dynamic linking has not been ported to all platforms. Operating systems
-in the BSD family (a.out binary format) can usually be ported to "DLD".
-The "dl" library (`#define SUN_DL' for SCM) was a proposed POSIX
-standard and may be available on other machines with "COFF" binary
-format. For notes about porting to MS-Windows and finishing the port
-to VMS *Note VMS Dynamic Linking::.
-
-"DLD" is a library package of C functions that performs "dynamic link
-editing" on GNU/Linux, VAX (Ultrix), Sun 3 (SunOS 3.4 and 4.0),
-SPARCstation (SunOS 4.0), Sequent Symmetry (Dynix), and Atari ST. It
-is available from:
-
- * ftp.gnu.org:pub/gnu/dld-3.3.tar.gz
-
-These notes about using libdl on SunOS are from `gcc.info':
-
- On a Sun, linking using GNU CC fails to find a shared library and
- reports that the library doesn't exist at all.
-
- This happens if you are using the GNU linker, because it does only
- static linking and looks only for unshared libraries. If you have
- a shared library with no unshared counterpart, the GNU linker
- won't find anything.
-
- We hope to make a linker which supports Sun shared libraries, but
- please don't ask when it will be finished-we don't know.
-
- Sun forgot to include a static version of `libdl.a' with some
- versions of SunOS (mainly 4.1). This results in undefined symbols
- when linking static binaries (that is, if you use `-static'). If
- you see undefined symbols `_dlclose', `_dlsym' or `_dlopen' when
- linking, compile and link against the file `mit/util/misc/dlsym.c'
- from the MIT version of X windows.

+2.4 Saving Executable Images |
============================
-
-The SLIB module "catalog" can be extended to define other
-`require'-able packages by adding calls to the Scheme source file
-`mkimpcat.scm'. Within `mkimpcat.scm', the following procedures are
-defined.
-
- -- Function: add-link feature object-file lib1 ...
- FEATURE should be a symbol. OBJECT-FILE should be a string naming
- a file containing compiled "object-code". Each LIBn argument
- should be either a string naming a library file or `#f'.
-
- If OBJECT-FILE exists, the `add-link' procedure registers symbol
- FEATURE so that the first time `require' is called with the symbol
- FEATURE as its argument, OBJECT-FILE and the LIB1 ... are
- dynamically linked into the executing SCM session.
-
- If OBJECT-FILE exists, `add-link' returns `#t', otherwise it
- returns `#f'.
-
- For example, to install a compiled dll `foo', add these lines to
- `mkimpcat.scm':
-
- (add-link 'foo
- (in-vicinity (implementation-vicinity) "foo"
- link:able-suffix))
-
-
- -- Function: add-alias alias feature
- ALIAS and FEATURE are symbols. The procedure `add-alias'
- registers ALIAS as an alias for FEATURE. An unspecified value is
- returned.
-
- `add-alias' causes `(require 'ALIAS)' to behave like `(require
- 'FEATURE)'.
-
- -- Function: add-source feature filename
- FEATURE is a symbol. FILENAME is a string naming a file
- containing Scheme source code. The procedure `add-source'
- registers FEATURE so that the first time `require' is called with
- the symbol FEATURE as its argument, the file FILENAME will be
- `load'ed. An unspecified value is returned.
-
-Remember to delete the file `slibcat' after modifying the file
-`mkimpcat.scm' in order to force SLIB to rebuild its cache.

+-------------------- |

+Here is an example of how to add a new type named `foo' to SCM. The |

+ |
+`long tc16_foo;' |
+ The type code which will be used to identify the new type. |
+ |
+`static smobfuns foosmob = {markfoo,freefoo,printfoo,equalpfoo};' |
+ smobfuns is a structure composed of 4 functions: |
+ |
+ typedef struct { |
+ SCM (*mark)P((SCM)); |
+ sizet (*free)P((CELLPTR)); |
+ int (*print)P((SCM exp, SCM port, int writing)); |
+ SCM (*equalp)P((SCM, SCM)); |
+ } smobfuns; |
+ |
+ `smob.mark' |
+ is a function of one argument of type `SCM' (the cell to |
+ mark) and returns type `SCM' which will then be marked. If |
+ no further objects need to be marked then return an immediate |
+ object such as `BOOL_F'. The smob cell itself will already |
+ have been marked. _Note_ This is different from SCM versions |
+ prior to 5c5. Only additional data specific to a smob type |
+ need be marked by `smob.mark'. |
+ |
+ 2 functions are provided: |
+ |
+ `markcdr(ptr)' |
+ returns `CDR(ptr)'. |
+ |
+ `mark0(ptr)' |
+ is a no-op used for smobs containing no additional `SCM' |
+ data. 0 may also be used in this case. |
+ |
+ `smob.free' |
+ is a function of one argument of type `CELLPTR' (the cell to |
+ collected) and returns type `sizet' which is the number of |
+ `malloc'ed bytes which were freed. `Smob.free' should free |
+ any `malloc'ed storage associated with this object. The |
+ function free0(ptr) is provided which does not free any |
+ storage and returns 0. |
+ |
+ `smob.print' |
+ is 0 or a function of 3 arguments. The first, of type `SCM', |
+ is the smob object. The second, of type `SCM', is the stream |
+ on which to write the result. The third, of type int, is 1 |
+ if the object should be `write'n, 0 if it should be |
+ `display'ed, and 2 if it should be `write'n for an error |
+ report. This function should return non-zero if it printed, |
+ and zero otherwise (in which case a hexadecimal number will |
+ be printed). |
+ |
+ `smob.equalp' |
+ is 0 or a function of 2 `SCM' arguments. Both of these |
+ arguments will be of type `tc16foo'. This function should |
+ return `BOOL_T' if the smobs are equal, `BOOL_F' if they are |
+ not. If `smob.equalp' is 0, `equal?' will return `BOOL_F' if |
+ they are not `eq?'. |
+ |
+`tc16_foo = newsmob(&foosmob);' |
+ Allocates the new type with the functions from `foosmob'. This |
+ line goes in an `init_' routine. |
+ |
+Promises and macros in `eval.c' and arbiters in `repl.c' provide |
+examples of SMOBs. There are a maximum of 256 SMOBs. Smobs that must |
+allocate blocks of memory should use, for example, `must_malloc' rather |
+than `malloc' *Note Allocating memory::. |

+6.2.3 Dynamic Linking Support |
+----------------------------- |
+ |
+Dynamic linking has not been ported to all platforms. Operating systems |
+in the BSD family (a.out binary format) can usually be ported to "DLD". |
+The "dl" library (`#define SUN_DL' for SCM) was a proposed POSIX |
+standard and may be available on other machines with "COFF" binary |
+format. For notes about porting to MS-Windows and finishing the port |
+to VMS *note VMS Dynamic Linking::. |
+ |
+"DLD" is a library package of C functions that performs "dynamic link |
+editing" on GNU/Linux, VAX (Ultrix), Sun 3 (SunOS 3.4 and 4.0), |
+SPARCstation (SunOS 4.0), Sequent Symmetry (Dynix), and Atari ST. It |
+is available from: |
+ |
+ * ftp.gnu.org:pub/gnu/dld-3.3.tar.gz |
+ |
+These notes about using libdl on SunOS are from `gcc.info': |
+ |
+ On a Sun, linking using GNU CC fails to find a shared library and |
+ reports that the library doesn't exist at all. |
+ |
+ This happens if you are using the GNU linker, because it does only |
+ static linking and looks only for unshared libraries. If you have |
+ a shared library with no unshared counterpart, the GNU linker |
+ won't find anything. |
+ |
+ We hope to make a linker which supports Sun shared libraries, but |
+ please don't ask when it will be finished-we don't know. |
+ |
+ Sun forgot to include a static version of `libdl.a' with some |
+ versions of SunOS (mainly 4.1). This results in undefined symbols |
+ when linking static binaries (that is, if you use `-static'). If |
+ you see undefined symbols `_dlclose', `_dlsym' or `_dlopen' when |
+ linking, compile and link against the file `mit/util/misc/dlsym.c' |
+ from the MIT version of X windows. |

+6.2.4 Configure Module Catalog |
+------------------------------ |
+ |
+The SLIB module "catalog" can be extended to define other |
+`require'-able packages by adding calls to the Scheme source file |
+`mkimpcat.scm'. Within `mkimpcat.scm', the following procedures are |
+defined. |
+ |
+ -- Function: add-link feature object-file lib1 ... |
+ FEATURE should be a symbol. OBJECT-FILE should be a string naming |
+ a file containing compiled "object-code". Each LIBn argument |
+ should be either a string naming a library file or `#f'. |
+ |
+ If OBJECT-FILE exists, the `add-link' procedure registers symbol |
+ FEATURE so that the first time `require' is called with the symbol |
+ FEATURE as its argument, OBJECT-FILE and the LIB1 ... are |
+ dynamically linked into the executing SCM session. |
+ |
+ If OBJECT-FILE exists, `add-link' returns `#t', otherwise it |
+ returns `#f'. |
+ |
+ For example, to install a compiled dll `foo', add these lines to |
+ `mkimpcat.scm': |
+ |
+ (add-link 'foo |
+ (in-vicinity (implementation-vicinity) "foo" |
+ link:able-suffix)) |
+ |
+ |
+ -- Function: add-alias alias feature |
+ ALIAS and FEATURE are symbols. The procedure `add-alias' |
+ registers ALIAS as an alias for FEATURE. An unspecified value is |
+ returned. |
+ |
+ `add-alias' causes `(require 'ALIAS)' to behave like `(require |
+ 'FEATURE)'. |
+ |
+ -- Function: add-source feature filename |
+ FEATURE is a symbol. FILENAME is a string naming a file |
+ containing Scheme source code. The procedure `add-source' |
+ registers FEATURE so that the first time `require' is called with |
+ the symbol FEATURE as its argument, the file FILENAME will be |
+ `load'ed. An unspecified value is returned. |

-

- returns a cclo (compiled closure) object of name `char *' NAME
- which takes `int' REQ required arguments, `int' OPT optional
- arguments, and a list of rest arguments if `int' REST is 1 (0 for
- not).
-
- `SCM (*fcn)()' is a pointer to a C function to do the work.
-
- The C function will always be called with REQ + OPT + REST
- arguments, optional arguments not supplied will be passed
- `UNDEFINED'. An error will be signaled if the subr is called with
- too many or too few arguments. Currently a total of 10 arguments
- may be specified, but increasing this limit should not be
- difficult.

-6.2.7 Defining Smobs
---------------------
-
-Here is an example of how to add a new type named `foo' to SCM. The
-following lines need to be added to your code:
-
-`long tc16_foo;'
- The type code which will be used to identify the new type.
-
-`static smobfuns foosmob = {markfoo,freefoo,printfoo,equalpfoo};'
- smobfuns is a structure composed of 4 functions:
-
- typedef struct {
- SCM (*mark)P((SCM));
- sizet (*free)P((CELLPTR));
- int (*print)P((SCM exp, SCM port, int writing));
- SCM (*equalp)P((SCM, SCM));
- } smobfuns;
-
- `smob.mark'
- is a function of one argument of type `SCM' (the cell to
- mark) and returns type `SCM' which will then be marked. If
- no further objects need to be marked then return an immediate
- object such as `BOOL_F'. The smob cell itself will already
- have been marked. _Note_ This is different from SCM versions
- prior to 5c5. Only additional data specific to a smob type
- need be marked by `smob.mark'.
-
- 2 functions are provided:
-
- `markcdr(ptr)'
- returns `CDR(ptr)'.
-
- `mark0(ptr)'
- is a no-op used for smobs containing no additional `SCM'
- data. 0 may also be used in this case.
-
- `smob.free'
- is a function of one argument of type `CELLPTR' (the cell to
- collected) and returns type `sizet' which is the number of
- `malloc'ed bytes which were freed. `Smob.free' should free
- any `malloc'ed storage associated with this object. The
- function free0(ptr) is provided which does not free any
- storage and returns 0.
-
- `smob.print'
- is 0 or a function of 3 arguments. The first, of type `SCM',
- is the smob object. The second, of type `SCM', is the stream
- on which to write the result. The third, of type int, is 1
- if the object should be `write'n, 0 if it should be
- `display'ed, and 2 if it should be `write'n for an error
- report. This function should return non-zero if it printed,
- and zero otherwise (in which case a hexadecimal number will
- be printed).
-
- `smob.equalp'
- is 0 or a function of 2 `SCM' arguments. Both of these
- arguments will be of type `tc16foo'. This function should
- return `BOOL_T' if the smobs are equal, `BOOL_F' if they are
- not. If `smob.equalp' is 0, `equal?' will return `BOOL_F' if
- they are not `eq?'.
-
-`tc16_foo = newsmob(&foosmob);'
- Allocates the new type with the functions from `foosmob'. This
- line goes in an `init_' routine.
-
-Promises and macros in `eval.c' and arbiters in `repl.c' provide
-examples of SMOBs. There are a maximum of 256 SMOBs. Smobs that must
-allocate blocks of memory should use, for example, `must_malloc' rather
-than `malloc' *Note Allocating memory::.

---------------------
-
-"ptob"s are similar to smobs but define new types of port to which SCM
-procedures can read or write. The following functions are defined in
-the `ptobfuns':
-
- typedef struct {
- SCM (*mark)P((SCM ptr));
- int (*free)P((FILE *p));
- int (*print)P((SCM exp, SCM port, int writing));
- SCM (*equalp)P((SCM, SCM));
- int (*fputc)P((int c, FILE *p));
- int (*fputs)P((char *s, FILE *p));
- sizet (*fwrite)P((char *s, sizet siz, sizet num, FILE *p));
- int (*fflush)P((FILE *stream));
- int (*fgetc)P((FILE *p));
- int (*fclose)P((FILE *p));
- } ptobfuns;
-
-The `.free' component to the structure takes a `FILE *' or other C
-construct as its argument, unlike `.free' in a smob, which takes the
-whole smob cell. Often, `.free' and `.fclose' can be the same
-function. See `fptob' and `pipob' in `sys.c' for examples of how to
-define ptobs. Ptobs that must allocate blocks of memory should use,
-for example, `must_malloc' rather than `malloc' *Note Allocating

+The SCM homepage contains links to precompiled binaries and source
+distributions.
+
+@noindent
+Downloads and instructions for installing the precompiled binaries are
+at @uref{http://people.csail.mit.edu/jaffer/SCM#QuickStart}.
+
+@noindent
+If there is no precompiled binary for your platform, you may be able
+to build from the source distribution. The rest of these instructions
+deal with building and installing SCM and SLIB from sources.
+
+@noindent
+Download (both SCM and SLIB of) either the last release or current
+development snapshot from
+@uref{http://people.csail.mit.edu/jaffer/SCM#BuildFromSource}.
+
+@noindent
+Unzip both the SCM and SLIB zips. For example, if you are working in
+@file{/usr/local/src/}, this will create directories
+@file{/usr/local/src/scm/} and @file{/usr/local/src/slib/}.
+
+
+@node GNU configure and make, Building SCM, Distributions, Installing SCM
+@section GNU configure and make
+
+@file{scm/configure} and @file{slib/configure} are Shell scripts which
+create the files @file{scm/config.status} and
+@file{slib/config.status} on Unix and MinGW systems.
+
+The @file{config.status} files are used (included) by the Makefile to
+control where the packages will be installed by @code{make install}.
+With GNU shell (bash) and utilities, the following commands should
+build and install SCM and SLIB:
+
+@example
+bash$ (cd slib; ./configure --prefix=/usr/local/)
+bash$ (cd scm
+> ./configure --prefix=/usr/local/
+> make scmlit
+> sudo make all
+> sudo make install)
+bash$ (cd slib; sudo make install)
+@end example
+
+If the install commands worked, skip to @ref{Testing}.
+
+If @file{configure} doesn't work on your system, make
+@file{scm/config.status} and @file{slib/config.status} be empty files.
+
+For additional help on using the @file{configure} script, run
+@w{@samp{./configure --help}}.
+
+@samp{make all} will attempt to create a dumped executable
+(@pxref{Saving Executable Images}), which has very small startup
+latency. If that fails, it will try to compile an ordinary @samp{scm}
+executable.
+
+Note that the compilation output may contain error messages; be
+concerned only if the @samp{make install} transcripts contain errors.
+
+@samp{sudo} runs the command after it as user @dfn{root}. On recent
+GNU/Linux systems, dumping requires that @samp{make all} be run as
+user root; hence the use of @samp{sudo}.
+
+@samp{make install} requires root privileges if you are installing to
+standard Unix locations as specified to (or defaulted by)
+@samp{./configure}. Note that this is independent of whether you did
+@w{@samp{sudo make all}} or @w{@samp{make all}}.

-These notes about using libdl on SunOS are from @file{gcc.info}:
-
-@quotation
-On a Sun, linking using GNU CC fails to find a shared library and
-reports that the library doesn't exist at all.
-
-This happens if you are using the GNU linker, because it does only
-static linking and looks only for unshared libraries. If you have
-a shared library with no unshared counterpart, the GNU linker
-won't find anything.
-
-We hope to make a linker which supports Sun shared libraries, but
-please don't ask when it will be finished--we don't know.
-
-Sun forgot to include a static version of @file{libdl.a} with some
-versions of SunOS (mainly 4.1). This results in undefined symbols when
-linking static binaries (that is, if you use @samp{-static}). If you
-see undefined symbols @samp{_dlclose}, @samp{_dlsym} or @samp{_dlopen}
-when linking, compile and link against the file
-@file{mit/util/misc/dlsym.c} from the MIT version of X windows.

-@noindent
-The SLIB module @dfn{catalog} can be extended to define other
-@code{require}-able packages by adding calls to the Scheme source file
-@file{mkimpcat.scm}. Within @file{mkimpcat.scm}, the following
-procedures are defined.
-
-@defun add-link feature object-file lib1 @dots{}
-@var{feature} should be a symbol. @var{object-file} should be a string
-naming a file containing compiled @dfn{object-code}. Each @var{lib}n
-argument should be either a string naming a library file or @code{#f}.
-
-If @var{object-file} exists, the @code{add-link} procedure registers
-symbol @var{feature} so that the first time @code{require} is called
-with the symbol @var{feature} as its argument, @var{object-file} and the
-@var{lib1} @dots{} are dynamically linked into the executing SCM
-session.
-
-If @var{object-file} exists, @code{add-link} returns @code{#t},
-otherwise it returns @code{#f}.
-
-For example, to install a compiled dll @file{foo}, add these lines to
-@file{mkimpcat.scm}:
-
-@example
- (add-link 'foo
- (in-vicinity (implementation-vicinity) "foo"
- link:able-suffix))
-@end example
-
-
-@end defun
-
-@defun add-alias alias feature
-@var{alias} and @var{feature} are symbols. The procedure
-@code{add-alias} registers @var{alias} as an alias for @var{feature}.
-An unspecified value is returned.
-
-@code{add-alias} causes @code{(require '@var{alias})} to behave like
-@code{(require '@var{feature})}.
-@end defun
-
-@defun add-source feature filename
-@var{feature} is a symbol. @var{filename} is a string naming a file
-containing Scheme source code. The procedure @code{add-source}
-registers @var{feature} so that the first time @code{require} is called
-with the symbol @var{feature} as its argument, the file @var{filename}
-will be @code{load}ed. An unspecified value is returned.
-@end defun
-
