* add expansion of default values in help text: the string
"%default" in an option's help string is expanded to str() of
that option's default value, or "none" if no default value.
* bug #955889: option default values that happen to be strings are
now processed in the same way as values from the command line; this
allows generation of nicer help when using custom types. Can
be disabled with parser.set_process_default_values(False).
* bug #960515: don't crash when generating help for callback
options that specify 'type', but not 'dest' or 'metavar'.
* feature #815264: change the default help format for short options
that take an argument from e.g. "-oARG" to "-o ARG"; add
set_short_opt_delimiter() and set_long_opt_delimiter() methods to
HelpFormatter to allow (slight) customization of the formatting.
* patch #736940: internationalize Optik: all built-in user-
targeted literal strings are passed through gettext.gettext(). (If
you want translations (.po files), they're not included with Python
-- you'll find them in the Optik source distribution from
http://optik.sourceforge.net/ .)
* bug #878453: respect $COLUMNS environment variable for
wrapping help output.
* feature #988122: expand "%prog" in the 'description' passed
to OptionParser, just like in the 'usage' and 'version' strings.
(This is *not* done in the 'description' passed to OptionGroup.)
* Fixed some long-hidden bugs revealed by the new PyUnit-based
test suite (thanks to Johannes Gijsbers the new test suite,
improved tests that caught the bugs, and the bug fixes).
* Make store_true/store_false store True/False rather than 1/0.
Details available in Optik's CVS repository.
recent version from Greg's CVS. I've changed the module docstring,
added a copyright notice, and renamed OptikError to OptParseError.
Still to do are documentation and unit tests.
