blib
Pragma for testing programs against a package
before the package has been installed. Given a
directory path, blib
starts in that directory to look for a
blib
directory structure; if it doesn’t find one there, it
works its way back
up five levels. If no path is specified, it starts looking in the
current directory.
blib
is meant to be used from the command line:
perl -Mblib script [args...] perl -Mblib=dir script [args...]
However, you can also call it from a Perl program:
use blib; use blib 'dir';
