Not sure how complex the script is, but generally asking users to edit
makefiles to match does not scale well at all. IMHO there's a sort of
goodness hierarchy when it comes to scripting:
1. one command that does everything, e.g. "./world" or "make world"
10. one command with arguments, and the exact arguments depend on the
system, e.g. "make DMD_HOME=/usr/bin/dmd MODEL=64"
100. asking the user to edit configuration files by hand in order to get
things done
1000. manual with a recipe with steps for getting things done
10000. folklore on how to get things done
There's a big drop in automation from one level to the next, and in
particular there's a surprising drop from the command to the command
with specific parameters.
