Perl module to find the path to the currently running perl

 The Devel::FindPerl module tries to find the path to the currently running
 perl. It implements a function to try (really really hard) to find the path to
 the perl running your program and another function to test if the perl in
 `$path` is the same perl as the currently running one.
 .
 SECURITY ALERT: This module by default does things that are not particularly
 secure (run programs based on external input).
