SCHEME CODE FOR STRING MANIPULATION
                                       
   This section of the repository contains Scheme code for string
   handling.
   
     * Stephen J. Bevan's implementation of character sets in Scheme
       (char-set.tar.gz).
     * Stephen J. Bevan's implementation of conc-strings, a form of
       string that supports efficient concatenation
       (conc-string.tar.gz).
     * An implementation of Common Lisp-style string formatting, by Dirk
       Lutzebaeck, Ken Dickey, and Aubrey Jaffer (format-2.2.tar.gz).
     * A scheme pretty-printer, by Marc Feeley (pp.scm).
     * Richard O'Keefe's generic read-string routine to port code to
       Scheme implementations that do not support a read-string or
       read-line primitive (readstring.oak).
     * Routines to unpack various sized integers from a string, by
       Stephen J. Bevan (string-03.tar.gz).
     * A collection of miscellaneous procedures that operate on strings,
       by Stephen J. Bevan (string.tar.gz).
     * Code to perform fast substring searches, by Ken Dickey
       (substr.scm).
