-Overview
-********
-
-  SLIB is a portable Scheme library meant to provide compatibility and
-utility functions for all standard Scheme implementations, and fixes
-several implementations which are non-conforming.  SLIB conforms to
-`Revised^4 Report on the Algorithmic Language Scheme' and the IEEE
-P1178 specification.  SLIB supports Unix and similar systems, VMS, and
-MS-DOS.

-
-Installation
-============
-
-  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.
-
-
-File: slib.info,  Node: Porting,  Next: Coding Standards,  Prev: Installation,  Up: Overview
-
-Porting
-=======
-
-  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' (*Note
-Require::) from the library; this will allow the use of `provide',
-`provided?', and `require' along with the "vicinity" functions
-(`vicinity' functions are documented in the section on Require.  *Note
-Require::).  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.
-
-
-File: slib.info,  Node: Coding Standards,  Next: Copyrights,  Prev: Porting,  Up: Overview
-
-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)' (*Note Require::).
-
-  `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 code 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.
-
-  Your package will be released sooner with SLIB if you send me a file
-which tests your code.  Please run this test *before* you send me the
-code!
-
-Modifications
--------------
-
-  Please document your changes.  A line or two for `ChangeLog' is
-sufficient for simple fixes or extensions.  Look at the format of
-`ChangeLog' to see what information is desired.  Please send me `diff'
-files from the latest SLIB distribution (remember to send `diff's of
-`slib.texi' and `ChangeLog').  This makes for less email traffic and
-makes it easier for me to integrate when more than one person is
-changing a file (this happens a lot with `slib.texi' and `*.init'
-files).
-
-  If someone else wrote a package you want to significantly modify,
-please try to contact the author, who may be working on a new version.
-This will insure against wasting effort on obsolete versions.
-
-  Please *do not* reformat the source code with your favorite
-beautifier, make 10 fixes, and send me the resulting source code.  I do
-not have the time to fish through 10000 diffs to find your 10 real
-fixes.

-
-Copyrights
-==========
-
-  This section has instructions for SLIB authors regarding copyrights.
-
-  Each package in SLIB must either be in the public domain, or come
-with a statement of terms permitting users to copy, redistribute and
-modify it.  The comments at the beginning of `require.scm' and
-`macwork.scm' illustrate copyright and appropriate terms.
-
-  If your code or changes amount to less than about 10 lines, you do not
-need to add your copyright or send a disclaimer.
-
-Putting code into the Public Domain
------------------------------------
-
-  In order to put code in the public domain you should sign a copyright
-disclaimer and send it to the SLIB maintainer.  Contact
-jaffer@ai.mit.edu for the address to mail the disclaimer to.
-
-     I, NAME, hereby affirm that I have placed the software package
-     NAME in the public domain.
-
-     I affirm that I am the sole author and sole copyright holder for
-     the software package, that I have the right to place this software
-     package in the public domain, and that I will do nothing to
-     undermine this status in the future.
-
-                                                     SIGNATURE AND DATE
-
-  This wording assumes that you are the sole author.  If you are not the
-sole author, the wording needs to be different.  If you don't want to be
-bothered with sending a letter every time you release or modify a
-module, make your letter say that it also applies to your future
-revisions of that module.
-
-  Make sure no employer has any claim to the copyright on the work you
-are submitting.  If there is any doubt, create a copyright disclaimer
-and have your employer sign it.  Mail the signed disclaimer to the SLIB
-maintainer.  Contact jaffer@ai.mit.edu for the address to mail the
-disclaimer to.  An example disclaimer follows.
-
-Explicit copying terms
-----------------------
-
-If you submit more than about 10 lines of code which you are not placing
-into the Public Domain (by sending me a disclaimer) you need to:
-
-   * Arrange that your name appears in a copyright line for the
-     appropriate year.   Multiple copyright lines are acceptable.
-
-   * With your copyright line, specify any terms you require to be
-     different from those already in the file.
-
-   * Make sure no employer has any claim to the copyright on the work
-     you are submitting.  If there is any doubt, create a copyright
-     disclaimer and have your employer sign it.  Mail the signed
-     disclaim to the SLIB maintainer.  Contact jaffer@ai.mit.edu for
-     the address to mail the disclaimer to.
-
-Example: Company Copyright Disclaimer
--------------------------------------
-
-  This disclaimer should be signed by a vice president or general
-manager of the company.  If you can't get at them, anyone else
-authorized to license out software produced there will do.  Here is a
-sample wording:
-
-     EMPLOYER Corporation hereby disclaims all copyright interest in
-     the program PROGRAM written by NAME.
-
-     EMPLOYER Corporation affirms that it has no other intellectual
-     property interest that would undermine this release, and will do
-     nothing to undermine it in the future.
-
-     SIGNATURE AND DATE,
-     NAME, TITLE, EMPLOYER Corporation

-Manual Conventions
-==================
-
-  Things that are labeled as Functions are called for their return
-values.  Things that are labeled as Procedures are called primarily for
-their side effects.
-
-  All examples throughout this text were produced using the `scm'
-Scheme implementation.
-
-  At the beginning of each section, there is a line that looks something
-like
-
-  `(require 'feature)'.
-
-This means that, in order to use `feature', you must include the line
-`(require 'feature)' somewhere in your code prior to the use of that
-feature.  `require' will make sure that the feature is loaded.

-Arrays
-======
-
-  `(require 'array)'
-
- - Function: array? OBJ
-     Returns `#t' if the OBJ is an array, and `#f' if not.
-
- - Function: make-array INITIAL-VALUE BOUND1 BOUND2 ...
-     Creates and returns an array that has as many dimensins as there
-     are BOUNDs and fills it with INITIAL-VALUE.
-
-  When constructing an array, BOUND is either an inclusive range of
-indices expressed as a two element list, or an upper bound expressed as
-a single integer.  So
-     (make-array 'foo 3 3) == (make-array 'foo '(0 2) '(0 2))
-
- - Function: make-shared-array ARRAY MAPPER BOUND1 BOUND2 ...
-     `make-shared-array' can be used to create shared subarrays of other
-     arrays.  The MAPPER is a function that translates coordinates in
-     the new array into coordinates in the old array.  A MAPPER must be
-     linear, and its range must stay within the bounds of the old
-     array, but it can be otherwise arbitrary.  A simple example:
-          (define fred (make-array #f 8 8))
-          (define freds-diagonal
-            (make-shared-array fred (lambda (i) (list i i)) 8))
-          (array-set! freds-diagonal 'foo 3)
-          (array-ref fred 3 3)
-             => FOO
-          (define freds-center
-            (make-shared-array fred (lambda (i j) (list (+ 3 i) (+ 3 j)))
-                               2 2))
-          (array-ref freds-center 0 0)
-             => FOO
-
- - Function: array-rank OBJ
-     Returns the number of dimensions of OBJ.  If OBJ is not an array,
-     0 is returned.
-
- - Function: array-shape ARRAY
-     `array-shape' returns a list of inclusive bounds.  So:
-          (array-shape (make-array 'foo 3 5))
-             => ((0 2) (0 4))
-
- - Function: array-dimensions ARRAY
-     `array-dimensions' is similar to `array-shape' but replaces
-     elements with a 0 minimum with one greater than the maximum. So:
-          (array-dimensions (make-array 'foo 3 5))
-             => (3 5)
-
- - Procedure: array-in-bounds? ARRAY INDEX1 INDEX2 ...
-     Returns `#t' if its arguments would be acceptable to `array-ref'.
-
- - Function: array-ref ARRAY INDEX1 INDEX2 ...
-     Returns the element at the `(INDEX1, INDEX2)' element in ARRAY.
-
- - Procedure: array-set! ARRAY NEW-VALUE INDEX1 INDEX2 ...
-
- - Function: array-1d-ref ARRAY INDEX
- - Function: array-2d-ref ARRAY INDEX INDEX
- - Function: array-3d-ref ARRAY INDEX INDEX INDEX
-
- - Procedure: array-1d-set! ARRAY NEW-VALUE INDEX
- - Procedure: array-2d-set! ARRAY NEW-VALUE INDEX INDEX
- - Procedure: array-3d-set! ARRAY NEW-VALUE INDEX INDEX INDEX
-
-  The functions are just fast versions of `array-ref' and `array-set!'
-that take a fixed number of arguments, and perform no bounds checking.
-
-  If you comment out the bounds checking code, this is about as
-efficient as you could ask for without help from the compiler.
-
-  An exercise left to the reader: implement the rest of APL.

-
-Array Mapping
-=============
-
-  `(require 'array-for-each)'
-
- - Function: array-map! ARRAY0 PROC ARRAY1 ...
-     ARRAY1, ... must have the same number of dimensions as ARRAY0 and
-     have a range for each index which includes the range for the
-     corresponding index in ARRAY0.  PROC is applied to each tuple of
-     elements of ARRAY1 ... and the result is stored as the
-     corresponding element in ARRAY0.  The value returned is
-     unspecified.  The order of application is unspecified.
-
- - Function: array-for-each PROC ARRAY0 ...
-     PROC is applied to each tuple of elements of ARRAY0 ...  in
-     row-major order.  The value returned is unspecified.
-
- - Function: array-indexes ARRAY
-     Returns an array of lists of indexes for ARRAY such that, if LI is
-     a list of indexes for which ARRAY is defined, (equal?  LI (apply
-     array-ref (array-indexes ARRAY) LI)).
-
- - Function: array-copy! SOURCE DESTINATION
-     Copies every element from vector or array SOURCE to the
-     corresponding element of DESTINATION.  DESTINATION must have the
-     same rank as SOURCE, and be at least as large in each dimension.
-     The order of copying is unspecified.

-
-Association Lists
-=================
-
-  `(require 'alist)'
-
-  Alist functions provide utilities for treating a list of key-value
-pairs as an associative database.  These functions take an equality
-predicate, PRED, as an argument.  This predicate should be repeatable,
-symmetric, and transitive.
-
-  Alist functions can be used with a secondary index method such as hash
-tables for improved performance.
-
- - Function: predicate->asso PRED
-     Returns an "association function" (like `assq', `assv', or
-     `assoc') corresponding to PRED.  The returned function returns a
-     key-value pair whose key is `pred'-equal to its first argument or
-     `#f' if no key in the alist is PRED-equal to the first argument.
-
- - Function: alist-inquirer PRED
-     Returns a procedure of 2 arguments, ALIST and KEY, which returns
-     the value associated with KEY in ALIST or `#f' if KEY does not
-     appear in ALIST.
-
- - Function: alist-associator PRED
-     Returns a procedure of 3 arguments, ALIST, KEY, and VALUE, which
-     returns an alist with KEY and VALUE associated.  Any previous
-     value associated with KEY will be lost.  This returned procedure
-     may or may not have side effects on its ALIST argument.  An
-     example of correct usage is:
-          (define put (alist-associator string-ci=?))
-          (define alist '())
-          (set! alist (put alist "Foo" 9))
-
- - Function: alist-remover PRED
-     Returns a procedure of 2 arguments, ALIST and KEY, which returns
-     an alist with an association whose KEY is key removed.  This
-     returned procedure may or may not have side effects on its ALIST
-     argument.  An example of correct usage is:
-          (define rem (alist-remover string-ci=?))
-          (set! alist (rem alist "foo"))
-
- - Function: alist-map PROC ALIST
-     Returns a new association list formed by mapping PROC over the
-     keys and values of ALIST.   PROC must be a function of 2 arguments
-     which returns the new value part.
-
- - Function: alist-for-each PROC ALIST
-     Applies PROC to each pair of keys and values of ALIST.  PROC must
-     be a function of 2 arguments.  The returned value is unspecified.
-
-
-File: slib.info,  Node: Collections,  Next: Dynamic Data Type,  Prev: Association Lists,  Up: Data Structures
-
-Collections
-===========
-
-  `(require 'collect)'
-
-  Routines for managing collections.  Collections are aggregate data
-structures supporting iteration over their elements, similar to the
-Dylan(TM) language, but with a different interface.  They have
-"elements" indexed by corresponding "keys", although the keys may be
-implicit (as with lists).
-
-  New types of collections may be defined as YASOS objects (*Note
-Yasos::).  They must support the following operations:
-   * `(collection? SELF)' (always returns `#t');
-
-   * `(size SELF)' returns the number of elements in the collection;
-
-   * `(print SELF PORT)' is a specialized print operation for the
-     collection which prints a suitable representation on the given
-     PORT or returns it as a string if PORT is `#t';
-
-   * `(gen-elts SELF)' returns a thunk which on successive invocations
-     yields elements of SELF in order or gives an error if it is
-     invoked more than `(size SELF)' times;
-
-   * `(gen-keys SELF)' is like `gen-elts', but yields the collection's
-     keys in order.
-
-  They might support specialized `for-each-key' and `for-each-elt'
-operations.
-
- - Function: collection? OBJ
-     A predicate, true initially of lists, vectors and strings.  New
-     sorts of collections must answer `#t' to `collection?'.
-
- - Procedure: map-elts PROC . COLLECTIONS
- - Procedure: do-elts PROC . COLLECTIONS
-     PROC is a procedure taking as many arguments as there are
-     COLLECTIONS (at least one).  The COLLECTIONS are iterated over in
-     their natural order and PROC is applied to the elements yielded by
-     each iteration in turn.  The order in which the arguments are
-     supplied corresponds to te order in which the COLLECTIONS appear.
-     `do-elts' is used when only side-effects of PROC are of interest
-     and its return value is unspecified.  `map-elts' returns a
-     collection (actually a vector) of the results of the applications
-     of PROC.
-
-     Example:
-          (map-elts + (list 1 2 3) (vector 1 2 3))
-             => #(2 4 6)
-
- - Procedure: map-keys PROC . COLLECTIONS
- - Procedure: do-keys PROC . COLLECTIONS
-     These are analogous to `map-elts' and `do-elts', but each
-     iteration is over the COLLECTIONS' *keys* rather than their
-     elements.
-
-     Example:
-          (map-keys + (list 1 2 3) (vector 1 2 3))
-             => #(0 2 4)
-
- - Procedure: for-each-key COLLECTION PROC
- - Procedure: for-each-elt COLLECTION PROC
-     These are like `do-keys' and `do-elts' but only for a single
-     collection; they are potentially more efficient.
-
- - Function: reduce PROC SEED . COLLECTIONS
-     A generalization of the list-based `comlist:reduce-init' (*Note
-     Lists as sequences::) to collections which will shadow the
-     list-based version if `(require 'collect)' follows `(require
-     'common-list-functions)' (*Note Common List Functions::).
-
-     Examples:
-          (reduce + 0 (vector 1 2 3))
-             => 6
-          (reduce union '() '((a b c) (b c d) (d a)))
-             => (c b d a).
-
- - Function: any? PRED . COLLECTIONS
-     A generalization of the list-based `some' (*Note Lists as
-     sequences::) to collections.
-
-     Example:
-          (any? odd? (list 2 3 4 5))
-             => #t
-
- - Function: every? PRED . COLLECTIONS
-     A generalization of the list-based `every' (*Note Lists as
-     sequences::) to collections.
-
-     Example:
-          (every? collection? '((1 2) #(1 2)))
-             => #t
-
- - Function: empty? COLLECTION
-     Returns `#t' iff there are no elements in COLLECTION.
-
-     `(empty? COLLECTION) == (zero? (size COLLECTION))'
-
- - Function: size COLLECTION
-     Returns the number of elements in COLLECTION.
-
- - Function: Setter LIST-REF
-     See *Note Setters:: for a definition of "setter".  N.B.  `(setter
-     list-ref)' doesn't work properly for element 0 of a list.
-
-  Here is a sample collection: `simple-table' which is also a `table'.
-     (define-predicate TABLE?)
-     (define-operation (LOOKUP table key failure-object))

-Dynamic Data Type
-=================
-
-  `(require 'dynamic)'
-
- - Function: make-dynamic OBJ
-     Create and returns a new "dynamic" whose global value is OBJ.
-
- - Function: dynamic? OBJ
-     Returns true if and only if OBJ is a dynamic.  No object
-     satisfying `dynamic?' satisfies any of the other standard type
-     predicates.
-
- - Function: dynamic-ref DYN
-     Return the value of the given dynamic in the current dynamic
-     environment.
-
- - Procedure: dynamic-set! DYN OBJ
-     Change the value of the given dynamic to OBJ in the current
-     dynamic environment.  The returned value is unspecified.
-
- - Function: call-with-dynamic-binding DYN OBJ THUNK
-     Invoke and return the value of the given thunk in a new, nested
-     dynamic environment in which the given dynamic has been bound to a
-     new location whose initial contents are the value OBJ.  This
-     dynamic environment has precisely the same extent as the
-     invocation of the thunk and is thus captured by continuations
-     created within that invocation and re-established by those
-     continuations when they are invoked.
-
-  The `dynamic-bind' macro is not implemented.

-Hash Tables
-===========
-
-  `(require 'hash-table)'
-
- - Function: predicate->hash PRED
-     Returns a hash function (like `hashq', `hashv', or `hash')
-     corresponding to the equality predicate PRED.  PRED should be
-     `eq?', `eqv?', `equal?', `=', `char=?', `char-ci=?', `string=?', or
-     `string-ci=?'.
-
-  A hash table is a vector of association lists.
-
- - Function: make-hash-table K
-     Returns a vector of K empty (association) lists.
-
-  Hash table functions provide utilities for an associative database.
-These functions take an equality predicate, PRED, as an argument.  PRED
-should be `eq?', `eqv?', `equal?', `=', `char=?', `char-ci=?',
-`string=?', or `string-ci=?'.
-
- - Function: predicate->hash-asso PRED
-     Returns a hash association function of 2 arguments, KEY and
-     HASHTAB, corresponding to PRED.  The returned function returns a
-     key-value pair whose key is PRED-equal to its first argument or
-     `#f' if no key in HASHTAB is PRED-equal to the first argument.
-
- - Function: hash-inquirer PRED
-     Returns a procedure of 3 arguments, `hashtab' and `key', which
-     returns the value associated with `key' in `hashtab' or `#f' if
-     key does not appear in `hashtab'.
-
- - Function: hash-associator PRED
-     Returns a procedure of 3 arguments, HASHTAB, KEY, and VALUE, which
-     modifies HASHTAB so that KEY and VALUE associated.  Any previous
-     value associated with KEY will be lost.
-
- - Function: hash-remover PRED
-     Returns a procedure of 2 arguments, HASHTAB and KEY, which
-     modifies HASHTAB so that the association whose key is KEY is
-     removed.
-
- - Function: hash-map PROC HASH-TABLE
-     Returns a new hash table formed by mapping PROC over the keys and
-     values of HASH-TABLE.  PROC must be a function of 2 arguments
-     which returns the new value part.
-
- - Function: hash-for-each PROC HASH-TABLE
-     Applies PROC to each pair of keys and values of HASH-TABLE.  PROC
-     must be a function of 2 arguments.  The returned value is
-     unspecified.

-Hashing
-=======
-
-  `(require 'hash)'
-
-  These hashing functions are for use in quickly classifying objects.
-Hash tables use these functions.
-
- - Function: hashq OBJ K
- - Function: hashv OBJ K
- - Function: hash OBJ K
-     Returns an exact non-negative integer less than K.  For each
-     non-negative integer less than K there are arguments OBJ for which
-     the hashing functions applied to OBJ and K returns that integer.
-
-     For `hashq', `(eq? obj1 obj2)' implies `(= (hashq obj1 k) (hashq
-     obj2))'.
-
-     For `hashv', `(eqv? obj1 obj2)' implies `(= (hashv obj1 k) (hashv
-     obj2))'.
-
-     For `hash', `(equal? obj1 obj2)' implies `(= (hash obj1 k) (hash
-     obj2))'.
-
-     `hash', `hashv', and `hashq' return in time bounded by a constant.
-     Notice that items having the same `hash' implies the items have
-     the same `hashv' implies the items have the same `hashq'.
-
-  `(require 'sierpinski)'
-
- - Function: make-sierpinski-indexer MAX-COORDINATE
-     Returns a procedure (eg hash-function) of 2 numeric arguments which
-     preserves *nearness* in its mapping from NxN to N.
-
-     MAX-COORDINATE is the maximum coordinate (a positive integer) of a
-     population of points.  The returned procedures is a function that
-     takes the x and y coordinates of a point, (non-negative integers)
-     and returns an integer corresponding to the relative position of
-     that point along a Sierpinski curve.  (You can think of this as
-     computing a (pseudo-) inverse of the Sierpinski spacefilling
-     curve.)
-
-     Example use: Make an indexer (hash-function) for integer points
-     lying in square of integer grid points [0,99]x[0,99]:
-          (define space-key (make-sierpinski-indexer 100))
-     Now let's compute the index of some points:
-          (space-key 24 78)               => 9206
-          (space-key 23 80)               => 9172
-
-     Note that locations (24, 78) and (23, 80) are near in index and
-     therefore, because the Sierpinski spacefilling curve is
-     continuous, we know they must also be near in the plane.  Nearness
-     in the plane does not, however, necessarily correspond to nearness
-     in index, although it *tends* to be so.
-
-     Example applications:
-
-          Sort points by Sierpinski index to get heuristic solution to
-          *travelling salesman problem*.  For details of performance,
-          see L. Platzman and J. Bartholdi, "Spacefilling curves and the
-          Euclidean travelling salesman problem", JACM 36(4):719-737
-          (October 1989) and references therein.
-
-
-          Use Sierpinski index as key by which to store 2-dimensional
-          data in a 1-dimensional data structure (such as a table).
-          Then locations that are near each other in 2-d space will
-          tend to be near each other in 1-d data structure; and
-          locations that are near in 1-d data structure will be near in
-          2-d space.  This can significantly speed retrieval from
-          secondary storage because contiguous regions in the plane
-          will tend to correspond to contiguous regions in secondary
-          storage.  (This is a standard technique for managing CAD/CAM
-          or geographic data.)
-
-
-  `(require 'soundex)'
-
- - Function: soundex NAME
-     Computes the *soundex* hash of NAME.  Returns a string of an
-     initial letter and up to three digits between 0 and 6.  Soundex
-     supposedly has the property that names that sound similar in normal
-     English pronunciation tend to map to the same key.
-
-     Soundex was a classic algorithm used for manual filing of personal
-     records before the advent of computers.  It performs adequately for
-     English names but has trouble with other nationalities.
-
-     See Knuth, Vol. 3 `Sorting and searching', pp 391-2
-
-     To manage unusual inputs, `soundex' omits all non-alphabetic
-     characters.  Consequently, in this implementation:
-
-          (soundex <string of blanks>)    => ""
-          (soundex "")                    => ""
-
-     Examples from Knuth:
-
-          (map soundex '("Euler" "Gauss" "Hilbert" "Knuth"
-                                 "Lloyd" "Lukasiewicz"))
-                  => ("E460" "G200" "H416" "K530" "L300" "L222")
-          
-          (map soundex '("Ellery" "Ghosh" "Heilbronn" "Kant"
-                                  "Ladd" "Lissajous"))
-                  => ("E460" "G200" "H416" "K530" "L300" "L222")
-
-     Some cases in which the algorithm fails (Knuth):
-
-          (map soundex '("Rogers" "Rodgers"))     => ("R262" "R326")
-          
-          (map soundex '("Sinclair" "St. Clair")) => ("S524" "S324")
-          
-          (map soundex '("Tchebysheff" "Chebyshev")) => ("T212" "C121")

-Chapter Ordering
-================
-
-  `(require 'chapter-order)'
-
-  The `chap:' functions deal with strings which are ordered like
-chapter numbers (or letters) in a book.  Each section of the string
-consists of consecutive numeric or consecutive aphabetic characters of
-like case.
-
- - Function: chap:string<? STRING1 STRING2
-     Returns #t if the first non-matching run of alphabetic upper-case
-     or the first non-matching run of alphabetic lower-case or the first
-     non-matching run of numeric characters of STRING1 is `string<?'
-     than the corresponding non-matching run of characters of STRING2.
-
-          (chap:string<? "a.9" "a.10")                    => #t
-          (chap:string<? "4c" "4aa")                      => #t
-          (chap:string<? "Revised^{3.99}" "Revised^{4}")  => #t
-
- - Function: chap:string>? STRING1 STRING2
- - Function: chap:string<=? STRING1 STRING2
- - Function: chap:string>=? STRING1 STRING2
-     Implement the corresponding chapter-order predicates.
-
- - Function: chap:next-string STRING
-     Returns the next string in the *chapter order*.  If STRING has no
-     alphabetic or numeric characters, `(string-append STRING "0")' is
-     returnd.  The argument to chap:next-string will always be
-     `chap:string<?' than the result.
-
-          (chap:next-string "a.9")                => "a.10"
-          (chap:next-string "4c")                 => "4d"
-          (chap:next-string "4z")                 => "4aa"
-          (chap:next-string "Revised^{4}")        => "Revised^{5}"

-Macroless Object System
-=======================
-
-  `(require 'object)'
-
-  This is the Macroless Object System written by Wade Humeniuk
-(whumeniu@datap.ca).  Conceptual Tributes: *Note Yasos::, MacScheme's
-%object, CLOS, Lack of R4RS macros.
-
-Concepts
---------
-
-OBJECT
-     An object is an ordered association-list (by `eq?') of methods
-     (procedures).  Methods can be added (`make-method!'), deleted
-     (`unmake-method!') and retrieved (`get-method').  Objects may
-     inherit methods from other objects.  The object binds to the
-     environment it was created in, allowing closures to be used to
-     hide private procedures and data.
-
-GENERIC-METHOD
-     A generic-method associates (in terms of `eq?') object's method.
-     This allows scheme function style to be used for objects.  The
-     calling scheme for using a generic method is `(generic-method
-     object param1 param2 ...)'.
-
-METHOD
-     A method is a procedure that exists in the object.  To use a method
-     get-method must be called to look-up the method.  Generic methods
-     implement the get-method functionality.  Methods may be added to an
-     object associated with any scheme obj in terms of eq?
-
-GENERIC-PREDICATE
-     A generic method that returns a boolean value for any scheme obj.
-
-PREDICATE
-     A object's method asscociated with a generic-predicate. Returns
-     `#t'.
-
-Procedures
-----------
-
- - Function: make-object ANCESTOR ...
-     Returns an object.  Current object implementation is a tagged
-     vector.  ANCESTORs are optional and must be objects in terms of
-     object?.  ANCESTORs methods are included in the object.  Multiple
-     ANCESTORs might associate the same generic-method with a method.
-     In this case the method of the ANCESTOR first appearing in the
-     list is the one returned by `get-method'.
-
- - Function: object? OBJ
-     Returns boolean value whether OBJ was created by make-object.
-
- - Function: make-generic-method EXCEPTION-PROCEDURE
-     Returns a procedure which be associated with an object's methods.
-     If EXCEPTION-PROCEDURE is specified then it is used to process
-     non-objects.
-
- - Function: make-generic-predicate
-     Returns a boolean procedure for any scheme object.
-
- - Function: make-method! OBJECT GENERIC-METHOD METHOD
-     Associates METHOD to the GENERIC-METHOD in the object.  The METHOD
-     overrides any previous association with the GENERIC-METHOD within
-     the object.  Using `unmake-method!' will restore the object's
-     previous association with the GENERIC-METHOD.  METHOD must be a
-     procedure.
-
- - Function: make-predicate! OBJECT GENERIC-PRECIATE
-     Makes a predicate method associated with the GENERIC-PREDICATE.
-
- - Function: unmake-method! OBJECT GENERIC-METHOD
-     Removes an object's association with a GENERIC-METHOD .
-
- - Function: get-method OBJECT GENERIC-METHOD
-     Returns the object's method associated (if any) with the
-     GENERIC-METHOD.  If no associated method exists an error is
-     flagged.

-Parameter lists
-===============
-
-  `(require 'parameters)'
-
-Arguments to procedures in scheme are distinguished from each other by
-their position in the procedure call.  This can be confusing when a
-procedure takes many arguments, many of which are not often used.
-
-A "parameter-list" is a way of passing named information to a
-procedure.  Procedures are also defined to set unused parameters to
-default values, check parameters, and combine parameter lists.
-
-A PARAMETER has the form `(parameter-name value1 ...)'.  This format
-allows for more than one value per parameter-name.
-
-A PARAMETER-LIST is a list of PARAMETERs, each with a different
-PARAMETER-NAME.
-
- - Function: make-parameter-list PARAMETER-NAMES
-     Returns an empty parameter-list with slots for PARAMETER-NAMES.
-
- - Function: parameter-list-ref PARAMETER-LIST PARAMETER-NAME
-     PARAMETER-NAME must name a valid slot of PARAMETER-LIST.
-     `parameter-list-ref' returns the value of parameter PARAMETER-NAME
-     of PARAMETER-LIST.
-
- - Procedure: adjoin-parameters! PARAMETER-LIST PARAMETER1 ...
-     Returns PARAMETER-LIST with PARAMETER1 ... merged in.
-
- - Procedure: parameter-list-expand EXPANDERS PARAMETER-LIST
-     EXPANDERS is a list of procedures whose order matches the order of
-     the PARAMETER-NAMEs in the call to `make-parameter-list' which
-     created PARAMETER-LIST.  For each non-false element of EXPANDERS
-     that procedure is mapped over the corresponding parameter value
-     and the returned parameter lists are merged into PARAMETER-LIST.
-
-     This process is repeated until PARAMETER-LIST stops growing.  The
-     value returned from `parameter-list-expand' is unspecified.
-
- - Function: fill-empty-parameters DEFAULTS PARAMETER-LIST
-     DEFAULTS is a list of lists whose order matches the order of the
-     PARAMETER-NAMEs in the call to `make-parameter-list' which created
-     PARAMETER-LIST.  `fill-empty-parameters' returns a new
-     parameter-list with each empty parameter filled with the
-     corresponding DEFAULT.
-
- - Function: check-parameters CHECKS PARAMETER-LIST
-     CHECKS is a list of procedures whose order matches the order of
-     the PARAMETER-NAMEs in the call to `make-parameter-list' which
-     created PARAMETER-LIST.
-
-     `check-parameters' returns PARAMETER-LIST if each CHECK of the
-     corresponding PARAMETER-LIST returns non-false.  If some CHECK
-     returns `#f' an error is signaled.
-
-In the following procedures ARITIES is a list of symbols.  The elements
-of `arities' can be:
-
-`single'
-     Requires a single parameter.
-
-`optional'
-     A single parameter or no parameter is acceptable.
-
-`boolean'
-     A single boolean parameter or zero parameters is acceptable.
-
-`nary'
-     Any number of parameters are acceptable.
-
-`nary1'
-     One or more of parameters are acceptable.
-
- - Function: parameter-list->arglist POSITIONS ARITIES TYPES
-          PARAMETER-LIST
-     Returns PARAMETER-LIST converted to an argument list.  Parameters
-     of ARITY type `single' and `boolean' are converted to the single
-     value associated with them.  The other ARITY types are converted
-     to lists of the value(s) of type TYPES.
-
-     POSITIONS is a list of positive integers whose order matches the
-     order of the PARAMETER-NAMEs in the call to `make-parameter-list'
-     which created PARAMETER-LIST.  The integers specify in which
-     argument position the corresponding parameter should appear.
-
- - Function: getopt->parameter-list ARGC ARGV OPTNAMES ARITIES TYPES
-          ALIASES
-     Returns ARGV converted to a parameter-list.  OPTNAMES are the
-     parameter-names.  ALIASES is a list of lists of strings and
-     elements of OPTNAMES.  Each of these strings which have length of
-     1 will be treated as a single - option by `getopt'.  Longer
-     strings will be treated as long-named options (*note getopt-:
-     Getopt.).
-
- - Function: getopt->arglist ARGC ARGV OPTNAMES POSITIONS ARITIES TYPES
-          DEFAULTS CHECKS ALIASES
-     Like `getopt->parameter-list', but converts ARGV to an
-     argument-list as specified by OPTNAMES, POSITIONS, ARITIES, TYPES,
-     DEFAULTS, CHECKS, and ALIASES.
-
-  These `getopt' functions can be used with SLIB relational databases.
-For an example, *Note make-command-server: Database Utilities.

-Priority Queues
-===============
-
-  `(require 'priority-queue)'
-
- - Function: make-heap PRED<?
-     Returns a binary heap suitable which can be used for priority queue
-     operations.
-
- - Function: heap-length HEAP
-     Returns the number of elements in HEAP.
-
- - Procedure: heap-insert! HEAP ITEM
-     Inserts ITEM into HEAP.  ITEM can be inserted multiple times.  The
-     value returned is unspecified.
-
- - Function: heap-extract-max! HEAP
-     Returns the item which is larger than all others according to the
-     PRED<? argument to `make-heap'.  If there are no items in HEAP, an
-     error is signaled.
-
-  The algorithm for priority queues was taken from `Introduction to
-Algorithms' by T. Cormen, C. Leiserson, R. Rivest.  1989 MIT Press.

-Queues
-======
-
-  `(require 'queue)'
-
-  A "queue" is a list where elements can be added to both the front and
-rear, and removed from the front (i.e., they are what are often called
-"dequeues").  A queue may also be used like a stack.
-
- - Function: make-queue
-     Returns a new, empty queue.
-
- - Function: queue? OBJ
-     Returns `#t' if OBJ is a queue.
-
- - Function: queue-empty? Q
-     Returns `#t' if the queue Q is empty.
-
- - Procedure: queue-push! Q DATUM
-     Adds DATUM to the front of queue Q.
-
- - Procedure: enquque! Q DATUM
-     Adds DATUM to the rear of queue Q.
-
-  All of the following functions raise an error if the queue Q is empty.
-
- - Function: queue-front Q
-     Returns the datum at the front of the queue Q.
-
- - Function: queue-rear Q
-     Returns the datum at the rear of the queue Q.
-
- - Prcoedure: queue-pop! Q
- - Procedure: dequeue! Q
-     Both of these procedures remove and return the datum at the front
-     of the queue.  `queue-pop!' is used to suggest that the queue is
-     being used like a stack.
