I couldn't find code:patha, I did find code:add_patha however. I assume
that's what you meant.
Which path should I add? "f:/code/foo" or "f:/code"?
I've tried both to no avail.
Do I need to compile the erl-file to beam first?
On a related note (as in the "trying to figure out what wrong" note), is
there any way I can trace the calls made when evaluating application:start?
I've tried to trace the shell process through the graphical Process
Manager but the part where it actually tries to find my app file is not
displayed. I guess I could use some Win32 utility to trace the system
calls, but an Erlang way would be nicer...
