As requested by diotalevi I attempted to write a script that utilized this in order to automatically check the perl libraries.

It did not work out the way I wanted, heck I can't seem to figure out how his script works. Here is the code, I sincerely hope someone else can make something useful out of it. Yes I really don't know what I am doing. This is yet over my head.

It searches @INC and generates a nice list of .pl .pm and .cgi files. 

#!/usr/bin/perl

my @dirs = @INC;
my @found = ();
my $crnt = '';

while(@dirs) {
  $crnt = shift @dirs;
  find(\&wanted, $crnt);
}

sub wanted {   #else construction to save stepping
  my $hit = $File::Find::name;  #Found file
  return if $hit eq $crnt; #Will otherwise be re-added, endless recurs

  if(-d $hit) {push @dirs, $hit}   #Subdirectory, add to list of dirs

    elsif($hit =~ m/\w+(\.pm|\.pl|\.cgi)$/) {push @found, $hit} #File

}

exit 0;
