perl module question

Shell Programming and Scripting

Couple questions on perl module..

1)where is the best place on web where it tells you what modules can do?

For example,

use Text::Autoformat

Where is the best place on line or via command line to find the exact capability of autoformat?

2)Is there already a perl module to read *.cap file(ethereal format)?

1) CPAN and probably the author's web page, if any
2) do a search in CPAN.
