I heartily second jethro's suggestion that you create a module rather than a script on CPAN. Scripts are very poor cousins compared to modules. My First contribution to CPAN was a script and I now really wish I'd done it as a module with a small 'demo' script to call it, or used the 'run a module' trick to allow its use as both a module and a script. For example:

use warnings;
use strict;

package RunableModule;

#... normal module stuff here

sub InterestingEntryPoint {
    print "Hey, it works\n";
}


# Execute the InterestingEntryPoint sub if being run as a script
InterestingEntryPoint () unless caller ();

1;
[download]

Prints:

Hey, it works
[download]

when executed from the command line as a script.
