Release Notes: This release loosens the rules, so you can get away with not specifiying a 'type' or 'dest' for many options. Some code has been refactored for easier subclassing. An examples directory has been added.
Release Notes: This release fixes the handling of bare "--" and "-" for consistency with GNU getopt. Documentation of callback options has been expanded. Methods for querying/manipulating an OptionParser's option list have been added, as well as a standard "--version" option.
