Finding installed modules

I was poking around at scripts to locate all installed modules and I'm a
little confused [or else I'm missing something]. *every* script I found
after a quick Google uses File::Find on @INC, but that seems wrong: my
guess [verified by a quick test pgm] is that 'use' does *NOT* search
subdirectories.

So: Is there some trick I'm not seeing in using File::Find to *prevent* it
from descending into subdirectories or is it really correct to do a
recursive search off of @INC to find modules??

[Assuming my guess here is correct, it looks to me like a better scheme is
just to use opendir/readdir to locate installed modules rather than ::Find,
no?]

Well, let's take an example. If @INC contains the path
/usr/lib/perl5/5.8.6 and Find.pm is located in
/usr/lib/perl5/5.8.6/File, how would 'use' find the File::Find module
without looking in the subdirectories?

Yeah, I realized that right after I posted my inquiry. The key part is to
use ::Find with "nochdir" so you can reconstruct the proper '::' name for
the subdirectoried [is that a word? :o)] modules.

Really? How about CPAN.pm? Look under Programming Examples:

http://search.cpan.org/~andk/CPAN-1.9205/lib/CPAN.pm

for $mod (CPAN::Shell->expand("Module","/./")) { ...
