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
(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 '..';
etc. if you really must.
Pollutes global name space for development only task.
