[erlang-questions] newb: Inside Erlang shell, go to directory and compile a module how to?

[nintendo]

I have one questions:
1) How do I change directory inside the Erlang shell, so that I can go
get a file and then compile this module into beam?

My module located in:
C:\Program Files\myproject\elang\mymodule.erl

Side note:

I did a complete install of erlang for windows and it doesn't set the
path for erlang.
I checked the documentation and searched on goolge, there is no
mention of setting the path.  I just added it to my windows path=C:
\Program Files\erl5.5.5\bin.

My 2cents:
I think you should add it to FAQ at http://www.erlang.org/faq/faq.html#AEN430
on hello world.
