Release 0.4 2004-04-13
  * The current http://srfi.schemers.org/srfi-37/srfi-37.html is not
    well formed. This is fixed in this version.
  * srfi-args-fold.html -> srfi-37.html.
  * As suggested by Sven Hartrumpf, a long option with a missing
    required option-argument (no "=") will not use the next
    command line argument as the option-argument.

Release 0.3
  * Added missing link to the GNU C Library Reference Manual to the proposed SRFI.
  * Fixed typo in the proposed SRFI.

Release 0.2
  * Added a description of folding to the proposed SRFI.

Release 0.1
  * Initial draft of the proposed SRFI.
  * Initial release of the reference implementation.
  * Doesn't rely on regular expression library (as do the existing
    implementations in scsh-utils and Chicken). It would be good to
    use a regular expression SRFI, if one comes along.
  * Uses SRFI 9: Defining Record Types.
  * Uses SRFI 11: Syntax for receiving multiple values.
  * Uses dash instead of dot for option accessors (as suggested by
    Felix L. Winkelmann).
