RE clean targets,
Hammering out a quick and dirty shell script to remove the generated files
can work if they fit a nice pattern. Another way is to use your version
control system for that, since it ~also knows which files in your tree are
generated. i.e. with something like git clean -xd{n,f}. But as will all
powerful commands for deleting things, be careful with that.
Actually, that gets me thinking... right now tup shares info with git (by
exporting and maintaining .gitignore files); is there something cool tup
could do using knowledge that git has? Maybe use the file hashes that git
already computed for all your source files? Maybe maintain a separate git
repo for you that actually versions all of the ~generated files? Cache
build results when you switch between branches (though that's getting into
ccache territory)
