Erlang refactoring with Emacs / Wrangler

With Wrangler, an extension to distel, one can now easily refactor Erlang programs with Emacs. Currently the following refactorings are supported:

• rename variable/function
• rename module
• generalize definition
• move a function definition to another module

At first attempt it seemed not to work, because it could not find header files from my application include directory, but after an e-mail exchange with the author I got it working, I just had to add the include directory path to list of source file directories known to wrangler.
