Changelog
---------

0.9.10
~~~~~~

 - **backward incompatible change**: if you are calling function to parse
   command line, earlier you could write ``main()`` to accomplish that
   task. This syntax is unavailable now (this will try to actually call a
   function), and you should use ``main(argv=sys.argv[1:])``.
 - if default value of an option is a fuction, always call it (None is passed in
   case when option is not supplied)

0.9.9
~~~~~
 - Now it's possible to call commands as regular function, where every
   non-supplied option will receive proper default (defined in option spec)
 - Globaloptions were simply dropped after parsing, fold them in regular options
 - Replace _ with - in command names, same as in options names
 - Respect empty strings as usage

0.9.8
~~~~~
Fixed bug with option names clashing with name of arguments for call_cmd. 

0.9.7
~~~~~
Library renamed to opster.

0.9.6
~~~~~
 - Checks for option definition: long name should be specified always, short
   name should be 1 character in length if available.
 - More specific argument name in guessed usage (this happens if you have not
   specified usage for command).
 - Ability to add global decorator for all commands. See ``test.py`` in
   repository for example: ``ui`` object, to handle verbose/quiet options.

0.9.5
~~~~~
Fixed bug, which prevented programs to work without arguments (displayed help
instead) if they are not using subcommands.

0.9.4
~~~~~
 - Ability to hide subcommands from help listing.
 - Append program name to subcommand usage.

0.9.3
~~~~~
Minor fix for setup.py, to avoid troubles with installing when there is no docs
in package.

0.9.2
~~~~~
Ability to call commands as regular functions, using arguments and keyword
arguments.
