package blib;

=head1 NAME

blib - Use MakeMaker's uninstalled version of a package

=head1 SYNOPSIS

perl -Mblib script [args...]

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

=head1 DESCRIPTION

Looks for MakeMaker-like I<'blib'> directory structure starting in
I<dir> (or current directory) and working back up to five levels of '..'.

Intended for use on command line with B<-M> option as a way of testing
arbitrary scripts against an uninstalled version of a package.

However it is possible to :

use blib;
 or
 use blib '..';

etc. if you really must.

=head1 BUGS

Pollutes global name space for development only task.
