Just released Executable v1.0. Executable lets you turn any class into
an command-line tool just by mixing in the Executable module.
Executable is very simple, and is on purpose. Its intent is less about
providing a feature rich CLI parser to use for your cool new command-
line app (though it certainly could be used for such), and more about
having a quick and dirty way to get code on the command line for
personal uses.
Check it out at: http://rubyworks.github.com/executable.
Any feedback on improving it is greatly appreciated.
