Loading extra modules.

[Tirthankar C.P]

Folks, how do I load extra modules? I got Date::Manip today, and I know I
should be putting it in the search-path of perl (@INC ?), but how do I do
it? Can I get a small code snippet? 

I do not have su privileges on the machine I work, and would like the
search-path to have my modules dir, $HOME/perlmodules in it. 

TIA, 
-tir
