=head1 NAME

Devel::Wherefore - Where the heck did these subroutines come from?

=head1 SYNOPSIS

  $ perl -MDevel::Wherefore myscript.pl

will dump symbols in main from myscript.pl

  $ perl -MDevel::Wherefore=App::opan $(which opan)

will dump symbols from package App::opan in the installed opan script

  $ perl -MDevel::Wherefore lib/Foo/Bar.pm

will dump symbols from package Foo::Bar (must be in lib/ or at root, doesn't
yet handle finding them in @INC, sorry).

Note that this code uses C to only compile the script so you
don't have to worry about it executing - does mean we'll miss runtime
require and import but hey, trade-offs.

=head1 DESCRIPTION

Rage driven development rapidly released.
