Tired of the sucktitude of automake command lines? Find it incredible that people could seriously claim to prefer command output so verbose that you actually miss all the warnings?

Prettify Automake finally fixes this. I've put up a deb that at least works on Edgy (but has some pretty shady changes; getting it to build was, um, interesting) here; re-autoreconf with that, then run configure with --enable-pretty-cmds to get much more sensible output:

  [C ] fbbits.c
  [C ] fbblt.c
  [C ] fbbltone.c
../../fb/fbbltone.c: In function "fbBltOne":
../../fb/fbbltone.c:354: warning: left-hand operand of comma expression has no effect
  [C ] fbbstore.c

Warnings! Visible! Amazing!
