<p>You're looking at it backwards. Don't decide on the code because of the filenames; decide on the filenames because of the code.</p>
<p>Choose a meaningful package name, like "Quux::Enhancer", and declare the package name in the module (somewhere near the top - the only things it makes sense to put before the package declaration are lexical pragma like <c>use strict; use warnings; use 5.010;</c>) using:</p>
<c>
package Quux::Enhancer;
</c>
<p>Now decide on which lib dir it's going to live inside. Often this will be a directory which is in perl's default <c>@INC</c> list. Within that directory create a subdirectory called <b>Quux</b>, and within that save your module as <b>Enhancer.pm</b>.</p>
<p>Then in your script, if that lib dir is not in perl's default <c>@INC</c>, include this:</p>
<c>
use lib '/path/to/lib'; ## not including 'Quux'!!
</c>
<p>And then in the script load the module like this:</p>
<c>
use Quux::Enhancer;
</c>
<p>If you ever need to move the file, then that's fine; no need to change anything within the module; just make sure it's always called <b>Enhancer.pm</b>, and always kept in a directory called <b>Quux</b>. Then <c>use lib</c> to tell your Perl script where to find it.</p>
