% perl -Mblib program [args…]
% perl -Mblib=DIR
program [args…]
From your Perl program:
use blib;
use blib 'DIR
';
This pragma is intended primarily as a way of testing arbitrary
Perl programs against an uninstalled version of a package through
Perl's -M
command-line switch. It assumes your
directory structure was produced by the standard ExtUtils::MakeMaker
module.
The pragma looks for a blib directory
structure starting in the directory named
DIR
(or current directory if none was
specified), and if it doesn't find a blib
directory there, works its way back up through your
".
." directories, scanning up to five levels of
parent directory.
