Erlang Refactoring

[Joe Armstrong (AL/EAB)]

Are there any Erlang refactoring programs that I can
download and use?

I want to do the following:

	I have a directory with Erlang modules

	   glurk.erl
	   foo_server.erl
	   ...

	And a Makefile

	And I have a renaming scheme

	Old Name         New Name
	glurk.erl        foo_bar_krulg.erl
	foo_server.erl   foo23_glunker.erl
      ...


I want some program that changes all the filenames and
module names in a consistent manner, and which tries
to keep the formatting of my programs intact.

Is there such a program? - << in the form of a function I
evaluate in the Erlang shell - ie with no incomprehensible GUI >>
