"Registering" an application

[Björn Bylander]

Hello,

I've created an application, foo, with a supervisor, gen_server etc 
according to the design principles. I've also created a directory 
structure for the application:
f:\code\foo\ebin
f:\code\foo\src
f:\code\foo\include
f:\code\foo\priv
I've put all of the erl files in the src directory and an foo.app file 
in ebin.

How do I "register" my app with the erlang system so that I, while 
developing, can start it with "application:start(foo)"?
Right now, all I get is "{error,{"no such file or directory","foo.app"}}".


TIA,
Björn
