To cite Larry Wall in perlfaq1

"a script is what you give the actors. A program is what you give the audience."

However, even within the Perl community, scripts seem to have pejorative karma, compared to, say, modules. A module is a complete entity bundled with collateral - documentation and tests.

In many module kits, the scripts supplied are "example scripts", and are not even considered deliverables. But, what do people actually run? Answer: scripts. Even a module like CPAN.pm has a thinly disguised script - disguised in a sub called shell.
