Include file

[gross, cedric]

I have a set of program to do which is using always same var.
 
So I would like to defined a small file where I defined my var (like
$database="toto" $host="localhost" etc..) and then include it in my
other program, but
How to do that ?
 
I try "use" but it's seems that is for complete module.
"require" seems to be for version behavior
and include seems not be supported...
 
I browse doc but I found nothing..
