What Modules are Installed?

Description: Based on vroom's suggestion(someplace), this script recurses through the directories in @INC, and prints out a list of files found there. You can also print only files ending in '.pm', that's why the 2 subroutines. I did this recently because my host throws an error at `perldoc perllocal`. (update: hmm, maybe I would have had better luck with `perlman perllocal`)
sub whats_installed
{
    require File::Find;

    for my $ix(0..$#INC)
    {
        print $INC[$ix], "\n";
        File::Find::find(sub { print $File::Find::name, "\n"},$INC[$ix
+]);
    }
}

sub whats_installed2
{
    require File::Find;

    for my $ix(0..$#INC)
    {
        print $INC[$ix],"\n";
        File::Find::find( sub {substr ($_, -3) eq '.pm' && print $File
+::Find::name, "\n";}, $INC[$ix]);
    }

}

    Example 12-3 in the Perl cookbook, pmdesc, prints a list of modules, their version, the directory they are installed in, and their descriptions. You can download it from O'Reilly.

[choroba]: No, if there are no threads, then the user wants to use MCE. If there are threads, the user can choose.
[1nickt]: choroba Understood. I'm wondering about the logic in a cpanfile. If the perl doesn't support threads, it's easy: require MCE. If the perl does support threads, as you say the user has a choice, so require both? Or, assume that irrespective of the choide
[1nickt]: ... choice, the threaded-perl user *probably* wants to use threads, therefore only require threads and leave MCE out, allowing the user to manually install if desired?
[choroba]: just require any of MCE and threads. Not sure if that's possible in the cpanfile, but should be possible early in the Makefile
[1nickt]: The app expects threads as default anyway, right?
[choroba]: that's true
[1nickt]: expects threads *to be* the default
[1nickt]: I think cpanfile can handle the logic. testing now.
