you're throwing away a build system that has been dominant for longer
than you have been alive. You should re-consider the impact of your
decision. How well do you know autoconf? You should know what you're
getting rid of before you do so, so that you can replace all of the bits
and pieces that you did not realize you were getting rid of.
