podpath

PODPATH(1p)						User Contributed Perl Documentation					       PODPATH(1p)

NAME

       podpath - print the path to the pod

DESCRIPTION

       This is just a front-end that calls either stdpods or pmpath depending on what it looks like.  It works on both regular the standard
       podpages and the module ones.

EXAMPLES

	   $ podpath Cwd
	   /usr/local/devperl/lib/5.00554/Cwd.pm

       It works with alternate installations, too:

	   $ devperl -S podpath perlfunc
	   /usr/local/devperl/lib/5.00554/pod/perlfunc.pod

	   $ oldperl -S podpath IO::Handle
	   /usr/lib/perl5/i386-linux/5.00404/IO/Handle.pm

	   $ filsperl -S podpath Thread
	   /usr/local/filsperl/lib/5.00554/i686-linux-thread/Thread.pm
