you mean absolute path at runtime? this is passed as args[0] in 
main(string[] args). though it contains not path but string used 
to launch ur program( for example "./program" when launched from 
its location, and full program path when double-clicked).

also you can use getcwd() from std.path.

but you can't rely on it as both of this takes "caller" location.
