Dear all,

I would like to announce the first public release of cmd2, an extension of the standard library's cmd with argument parsing, here: https://github.com/anntzer/cmd2.

Cmd2 is an extension built around the excellent cmd module of the standard
library.  Cmd allows one to build simple custom shells using ``do_*`` methods,
taking care in particular of the REPL loop and the interactive help.  However,
no facility is given for parsing the argument line (do_* methods are passed the
rest of the line as a single string argument).

With Cmd2, ``do_*`` methods are type-annotated, either using Python 3's
function annotation syntax, or with an ad-hoc ``annotate`` decorator, allowing
the dispatcher to parse the argument list for them.
