This probably has a striaghtforward answer but i couldnt find one on the net or in a book.

I am requiring several .pl scripts from a .cgi script with success (eg require "datasource.pl";). everything works fine.

I have however seen many perl script which use the following code before requiring anything,

use lib qw(     /usr/local/etc/httpd/cgi-bin);

My question is
1)Do you HAVE to use 'use lib' if you are requireing other scripts.
2)In what situation would i use 'use lib'.

THanks
