+NOTES
+
+stringhax.scm provides several string-hacking procedures.
+
+
+
+
+DEFINITIONS AND DESCRIPTIONS
+
+
+procedure
+string-map procedure string --> string
+
+Does a 'map' on each character of STRING and returns the result, a
+newly allocated string. PROCEDURE takes a character and should return
+a character.
+
+
+procedure
+downcase-string string --> string
+upcase-string string --> string
+
+Do what you expect: converts STRING to downcase or upcase
+respectively, using char-downcase or char-upcase respectively. The
+result is a newly allocated string.
+
+
+procedure 
+char-set-index string char-set [start] --> number
+char-set-rindex string char-set [start] --> number
+
+Returns the index of the first character that is in
+char-set. char-set-index searches from left to r0.6/scsh/lib/char-package.scmight, char-set-rindex
+from right to left. START is the index from where to start from and
+defaults to 0 in char-set-index and (string-length STRING) in
+char-set-rindex. If the search fails, #f is returned.
+
+
+procedure
+string-reduce default construct string --> string
+
+Does a "fold-right" on string. The resulting string is
+(CONSTRUCT ... (CONSTRUCT STRING[1] (CONSTRUCT STRING[0] DEFAULT)) ...)
+Example:
+
+(string-reduce "" (lambda (char str) 
+                    (string-append str (string (char-downcase char)))) 
+               "DOWNCASE")
+
+==> "downcase"
+
+
+procedure
+string-prefix? prefix string --> boolean
+string-suffix? suffix string --> boolean
+
+Return #t if PREFIX/SUFFIX is a real prefix/suffix of STRING,
+otherwise return #f. Real prefix/suffix mean that STRING may not be a
+prefix/suffix of PREFIX/SUFFIX.
+
+
+procedure 
+skip-whitespace string --> number
+
+Returns the index of the first character in STRING that is not a
+whitespace (as defined in char-set:whitespace). If there isn't such a
+character, #f is returned.
+
+
+procedure
+trim-spaces string --> string
+
+Returns a newly allocated string being STRING without leading or
+trailing spaces (not whitespaces!).
