[erlang-questions] Auto recompilation

mochiweb includes a module "reloader" that will monitor any loaded
.beam files for changes and automatically reload them and try to run
an exported test/0 method if available:


I typically edit files in Emacs, run Erlang in a separate terminal
(not using any of erlang-mode's integration), run M-x recompile in
Emacs to rebuild files, and the Erlang process will detect the new
.beams and run our regression tests for the modules.
