.pm files are generally classes, although they can be subroutine libraries
as well. Perl's OO paradigm is pretty simple: if you call something as
$object->foo() or Object_Class->foo() the object or the classname are
passed to foo() as the first parameter.. as long as the object has been
blessed. Grep for 'bless'. If no bless, then it's a subroutine library;
then look for -i 'export'.

.pm files are generally included into some main proggie with use or
require. There is a notion of class persistence; if you're running
mod_perl, that persistence stays for the lifetime of the worker AFAIK, and
you have to restart apache to get them to reload.

Using warn or carp to make the code chatty is the low tech way to debug.
There are others (you can get really fancy if you care to).

If you use CGI.pm, then if you call the main cgi with perl -d it will ask
you for the parameters in a syntax which predates YAML.

The address at the bottom of this message requires "I-ACK" on the subject
or from lines..
