See the current Perl documentation for lib:blib.

Here is our local, out-dated (pre-5.6) version:

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; 
 use blib '..';

etc. if you really must.


Pollutes global name space for development only task.
