Abstract
It’s easy to write command-line programs in Perl. There are a million option parsers to choose from, and Perl makes it easy to deal with input, output, and all that stuff.
Once your program has gotten beyond just taking a few switches, though, it can be difficult to maintain a clear interface and well-tested code. App::Cmd is a lightweight framework for writing easy to manage CLI programs.
This talk provides an introduction to writing programs with App::Cmd.

Another talk from the Pittsburgh Perl Workshop (PPW), whose schedule has vanished.
