Anthony Ramine gave me a tip on how to build only modified erl files 
using make's functionality directly, I'll try it out tomorrow and report 
back.

My reasons in short:

  *  Slow (especially for running tests)
  *  Annoying (it does recursion by default; and might do recursion in 
some cases but not in others later, which is as bad)
  *  Inconvenient (it does funny things to its ct stuff which makes it 
much slower and less practical than ct_run, and I run tests all the time)
  *  Unstable (options change at regular intervals)

I actually removed it initially to improve my development life (where I 
do a lot of dialyzing and running tests), then decided to stop using it 
entirely. I use Makefiles anyway, and rebar's functionality is 
replicated in just a dozen more lines compared to the original Makefile.

I still support rebar for people who use my projects, I think it's the 
best current solution to get started using Erlang quickly, I just don't 
use it for my own development needs.

As for releases, relcool[1] sounds damn sexy, I have been advising them 
a little on how to handle release upgrades, and will be using it 
starting next week.
