Let me get this straight:

• ~/abc/moo.pl
• ~/abc/cow.pm
• ~/zyx/cow.pm
• current directory is ~/zyx

moo.pl has:

• use cow
• use lib 'cow'

When i execute moo.pl, . is set to ~/zyx, so:

• use cow means ~/zyx/cow.pm
• use lib 'cow' means ~/abc/cow.pm

Did i get it right that, basically, there is a difference between the "current" directory and the directory of the pl file. Or, put another way, if i keep all my project files in the same directory, like we do during development, and the directory may change, and the directory i execute it from may change, "use lib" will work "as expected".

No. Read lib. use lib 'cow'; is the standard, clean alternative to unshift @INC, 'cow'; It adds a directory to the search locations; it does not identify or pull in any files into the current program.

if i keep all my project files in the same directory, ... "use lib" will work "as expected".

No; if you do that, then you never need use lib ... at all, for the simple reason that '.' is in @INC by default.

Please give an example. I would like to get this clear.
