SYNOPSIS
perl -Mblib script [args...]
perl -Mblib=dir script [args...]
DESCRIPTION
Looks for MakeMaker-like 'blib' directory structure starting in dir (or current directory) and working back up to five levels of '..'.Intended for use on command line with -M option as a way of testing arbitrary scripts against an uninstalled version of a package.
However it is possible to :
use blib; or use blib '..';
etc. if you really must.
