=head1 NAME
pminst - find modules whose names match this pattern
=head1 SYNOPSIS
pminst [B<-s>] [B<-l>] [I<pattern>]
=head1 DESCRIPTION
Without argumnets, show the names of all installed modules. Given a
pattern, show all module names that match it. The B<-l> flag will show
the full pathname. The B<-s> flag will separate the base directory from
@INC from the module portion itself.
=head1 EXAMPLES
$ pminst
(lists all installed modules)
$ pminst Carp
CGI::Carp
Carp
$ pminst ^IO::
IO::Socket::INET
IO::Socket::UNIX
IO::Select
IO::Socket
IO::Poll
IO::Handle
IO::Pipe
IO::Seekable
IO::Dir
IO::File
$ pminst '(?i)io'
IO::Socket::INET
IO::Socket::UNIX
IO::Select
IO::Socket
IO::Poll
IO::Handle
IO::Pipe
IO::Seekable
IO::Dir
IO::File

Pod::Functions
The -s flag provides output with the directory separated
by a space:
$ pminst -s | sort +1
(lists all modules, sorted by name, but with where they
came from)
$ oldperl -S pminst -s IO
/usr/lib/perl5/i386-linux/5.00404 IO::File
/usr/lib/perl5/i386-linux/5.00404 IO::Handle

The -l flag gives full paths:
