+Rubygem implementation of docopt.
+
+Docopt helps you:
+- define interface for your command-line app, and
+- automatically generate parser for it.
+
+Docopt is based on conventions that have been used for decades in help messages
+and man pages for describing a program's interface. An interface description in
+docopt is such a help message, but formalized.
