Imho a useless Module: This is Perl, not PHP.
Perl already has enough working ways to provide information about the Perl binary and installed modules. Just do "perl -V" and play (read the POD) a bit with CPAN shell and/or CPANPLUS.
And hey, why does phpinfo() on php-cli return html crap?
Oops, no seperation between data-retrieving and output?!
Do we really need to "port" this "level" to Perl? I doubt.
