In perl, @INC is a perl-defined array with the list of directories that perl will search when it needs to find scripts or modules that are called with "do", "require" or "use".

A common faq with perl beginners is, "How can I make perl search such-and-such directory?" and one answer is to manipulate @INC:

     BEGIN {
          push( "/some/directory", @INC );
     }

One may also use the "lib" pseudo module, as such:

use lib "/path/to/my/perl/lib";

The end result is the same, but the code is a bit cleaner.
