Based on PR#41674 by Kamel Derouiche.
1.5.3 (23 Jul 2006)
-------------------
* Port r47026 from Python svn repository: fix unit test so
it doesn't screw up other tests in the Python test suite.
1.5.2 (22 Jul 2006)
-------------------
* Minor documentation tweaks.
* SF bug #1498146: handle Unicode help strings (affects option help,
description, and epilog).
1.5.1 (19 Apr 2006)
-------------------
* Fix so the 'merge' script works again (bugs spotted, and mostly
fixed, by Andrea 'fwyzard' Bocci).
* SF bug #1145594: add 'destroy()' method to OptionParser so
applications can explicitly break reference cycles, making life
easier for Python's garbage collector.
* SF feature #988126: add 'epilog' attribute to OptionParser
(and constructor arg): paragraph of text to print after the
main option help.
* Corrected French translation (po/optik/fr.po) (Laurent Laporte).
* Beefed up reference guide.
* Backported to Python 2.0/2.1 (Giovanni Bajo).
1.5 (6 Dec 2004)
----------------
(All changes first released in Optik 1.5a1 except as noted.)
* Optik now requires Python 2.2 or later.
* 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.
* SF 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).
* SF bug #960515: don't crash when generating help for callback
options that specify 'type', but not 'dest' or 'metavar'.
* SF 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.
* SF patch #736940: internationalize Optik: all built-in user-
targeted literal strings are passed through gettext.gettext(). Also
added po/ directory for message catalog and translations, so that
Optik-based applications have a single place to go for translations
of Optik's built-in messags. Include translations for Danish and
German (thanks to Frederik S. Olesen and Martin v. L
respectively), and partial translations for French (by me).
* SF bug #878453 (Python): respect $COLUMNS environment variable for
wrapping help output.
* SF feature #964317: allow type objects to specify option types;
allow "str" as an alias for "string".
* SF 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.)
* Added HTML-formatted docs to the source distribution (in addition
to the reStructuredText source files).
* Added three new examples: custom_source.py, custom_type.py, and
no_help.py.
* Remove the old, broken "ignore" option conflict handler -- was
only needed for compatibility with Optik 1.1.
* Move documentation into docs/ directory, and write a script
(mkpydoc) to automatically convert it to LaTeX for the Python
standard library manual. Many documentation improvements.
(1.5a2)
* SF #997100: attempt to avoid triggering a FutureWarning in
__repr__() when using id() with "%x" (1.5a2).
* SF #1048725: fix typo in Values.__eq__() introduced in 1.5a1.
* Fix test script so it plays nice when being run with other test
scripts (as in the Python test suite) (1.5a2).
* SF patch #870807: allow users to specify integer option arguments
in hexadecimal, octal, or binary with leading "0x", "0", or "0b"
(1.5 final).
* SF feature #1050184: add 'append_const' action (patch by
Andrea 'fwyzard' Bocci) (1.5 final).
* Keep going if importing gettext fails (so optparse can be used
in the Python build process) (1.5 final).
Python 2.3 (29 July 2003)
-------------------------
(A couple of fixes were made in Optik in time for its inclusion in
Python 2.3 as optparse, but I never got around to making a corresponding
bug-fix release of Optik.)
* Add __all__ to optik package and optparse module (fixes
SF bug #728563).
* Fix so the 'prog' attribute of OptionParser (which was
surreptitiously added in 1.4.1, but undocumented, untested,
and not working) actually works.
1.4.1 (20 Apr 2003)
-------------------
* Changed to use the new textwrap module included with Python 2.3.
Includes a copy of textwrap.py for use with older Python versions.
* Set __all__ in each of the optik.* modules, to make life easier for
optik/__init__.py.
* Rewrote the test suite to use PyUnit, and added some new tests
that revealed some long-hidden bugs. Fixed those bugs.
(Thanks to Johannes Gijsbers for doing all the work!)
* For versions of Python with builtin True and False values (ie.
Python 2.2.1 and later), make store_true/store_false use them.
* Add forwards-compatibility 'optparse' module, so scripts can
import from 'optparse' and work under base Python 2.3, or
under older Pythons with Optik 1.4.1 or later installed.
