Using modules

[Ryan Davis/Pamela Karr]

How can I change my @INC variable?  Can I just:

@INC = (@INC, "/home/me/libs/");

It seems like I would need to change it before my perl program starts...
Also, if I put a .pm file in one of the @INC dirs, will I be able to:

use module;

even if it is not in the main system perl libs?

Thanks,
Ryan Davis
