Right, but just note that sometimes the statement "use lib '.';" can be 
useful. While "." is already in @INC, it's usuaully the last element. use lib 
prepends the path (in our case ".") to @INC and so now, the modules at the 
local dir are used before the ones at the more global paths. (instead of the 
opposite).

So, if you want to override some modules that are already found in your 
system, you need to use this statement or something similar. I found the need 
to use it for a web-application I wrote for a server I'm co-admining. 

But excuse me, I now need to hide so that the Perl gestapo won't hunt me down 
and execute me.
