+
+ INSTALLATION INSTRUCTIONS
+
+ Check the manifest in `README' to find a configuration file for your
+Scheme implementation. Initialization files for most IEEE P1178
+compliant Scheme Implementations are included with this distribution.
+
+ If the Scheme implementation supports `getenv', then the value of the
+shell environment variable SCHEME_LIBRARY_PATH will be used for
+`(library-vicinity)' if it is defined. Currently, Chez, Elk,
+MITScheme, scheme->c, VSCM, and SCM support `getenv'.
+
+ You should check the definitions of `software-type',
+`scheme-implementation-version', `implementation-vicinity', and
+`library-vicinity' in the initialization file. There are comments in
+the file for how to configure it.
+
+ Once this is done you can modify the startup file for your Scheme
+implementation to `load' this initialization file. SLIB is then
+installed.
+
+ Multiple implementations of Scheme can all use the same SLIB
+directory. Simply configure each implementation's initialization file
+as outlined above.
+
+ The SCM implementation does not require any initialization file as
+SLIB support is already built in to SCM. See the documentation with
+SCM for installation instructions.
+
+ SLIB includes methods to create heap images for the VSCM and Scheme48
+implementations. The instructions for creating a VSCM image are in
+comments in `vscm.init'. To make a Scheme48 image, `cd' to the SLIB
+directory and type `make slib48'. This will also create a shell script
+with the name `slib48' which will invoke the saved image.
+
+ PORTING INSTRUCTIONS
+
+ If there is no initialization file for your Scheme implementation, you
+will have to create one. Your Scheme implementation must be largely
+compliant with `IEEE Std 1178-1990' or `Revised^4 Report on the
+Algorithmic Language Scheme' to support SLIB.
+
+ `Template.scm' is an example configuration file. The comments inside
+will direct you on how to customize it to reflect your system. Give
+your new initialization file the implementation's name with `.init'
+appended. For instance, if you were porting `foo-scheme' then the
+initialization file might be called `foo.init'.
+
+ Your customized version should then be loaded as part of your scheme
+implementation's initialization. It will load `require.scm' from the
+library; this will allow the use of `provide', `provided?', and
+`require' along with the "vicinity" functions. The rest of the
+library will then be accessible in a system independent fashion.
+
+ Please mail new working configuration files to `jaffer@ai.mit.edu' so
+that they can be included in the SLIB distribution.
+
+ CODING STANDARDS
+
+ All library packages are written in IEEE P1178 Scheme and assume that
+a configuration file and `require.scm' package have already been
+loaded. Other versions of Scheme can be supported in library packages
+as well by using, for example, `(provided? 'rev3-report)' or `(require
+'rev3-report)'.
+
+ `require.scm' defines `*catalog*', an association list of module
+names and filenames. When a new package is added to the library, an
+entry should be added to `require.scm'. Local packages can also be
+added to `*catalog*' and even shadow entries already in the table.
+
+ The module name and `:' should prefix each symbol defined in the
+package. Definitions for external use should then be exported by having
+`(define foo module-name:foo)'.
+
+ Submitted packages should not duplicate routines which are already in
+SLIB files. Use `require' to force those features to be supported in
+your package. Care should be taken that there are no circularities in
+the `require's and `load's between the library packages.
+
+ Documentation should be provided in Emacs Texinfo format if possible,
+But documentation must be provided.
