```{index} single: blib (pragma) ``` # blib Use MakeMaker's uninstalled version of a package ## SYNOPSIS ```text 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 : ```perl use blib; or use blib '..'; ``` etc. if you really must. ## BUGS Pollutes global name space for development only task. ## AUTHOR Nick Ing-Simmons nik@tiuk.ti.com
