How to create a library, I mean an external file that holds functions just like std.stdio

first way - put this "print" function into its own module, 
compile your "client" program simply adding print module in 
source list.

example: "dmd yourmain.d print.d"

(this way you actually just adding all code from "print" module 
to your program)



second way(phobos actually using this) - put your "print" in its 
own module and compile it as static library. then when compiling 
your client program link with this lib and add import search path 
with -I to location where print can be found.

example: "dmd print.d -lib && dmd yourmain.d print.lib"

(with this way only used stuff gets imported(function/types/etc. 
definitions), and then linked at compile time with static lib 
which contains actual compiled code for that function).
