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 arbitary scripts against an uninstalled version
of a package.
However it is possible to : 
 use blib; 
 or 
 use blib '..';
etc. if you really must.
Pollutes global name space for development only task.
