blib - Use MakeMaker's uninstalled version of a package

perl -Mblib script [args...]
perl -Mblib=dir script [args...]

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;
use blib '..';

etc. if you really must.

Pollutes global name space for development only task.
