ABOUT
=====
CommandLine is a library that greatly simplifies the repetitive
process of building a command line user interface for your
applications. It's 'ruby-like' usage style streamlines application
development so that even applications with numerous configuration
options can be quickly put together. CommandLine automatically builds
friendly usage and help screens that are nicely formatted for the
user. No longer is starting an application a pain where you have to
copy boiler plate code (or a previous application) and retype
repetitive code to get an application started

HISTORY
=======
After poking around in a few corporations, it was evident that
option parsing was not well understood. Therefore, many inhouse
tools were built that did not conform to any of the POSIX, Gnu or XTools
option styles. CommandLine::OptionParser was developed so that
new applications could be written that conformed to accepted standards,
but non-standard option configurations could be handled as well
to support legacy interfaces.
Once the option parsing was written, there was a need to streamline
the repetitive tasks in setting up an application. The original
boilerplate was simple, but after taking a few cues from
rails, a significant amount of functionality was added to
Application that make it a very useful tool yet simple to use.
More information and usage scenarios on OptionParser can be found at:
http://rubyforge.org/projects/optionparser/
ACKNOWLEDGEMENTS

Is there an entry on the RAA for CommandLine? I didn't see one last
time I looked.
Thanks,

Nope. Haven't done that. Should I?

Most definitely. I do search RubyForge sometimes, but generally I rely
on the RAA to find things, as do most people I imagine.
Thanks.

I tend to forget to look in RAA. I go for RubyForge, then Google.
