Technically, it is easy. Only have two mechanisms for data files: one
for installed data files, and one for extra source files (as done in
automake for example):
 -  Extra files only need to be listed (and included in sdist)
 -  Install data files need a target directory. One of the problem
with distutils here is that you can only hardcode paths - in my own
packaging solution, I use $path variables so that any path defined
internally can be reused ($bindir, etc...); something similar could be
defined in distutils. The remaining issue is then how to resolve the
final target: installing src/foo.dat into $datadir installs
$datadir/src/foo.dat or $datadir/foo.dat ? In my own package, I use a
source directory argument, to reproduce the nobase scheme of automake:


The way I did it is to have:


The files include/foo.h is installed as /usr/include/foo.h and
include/sys/bar.h is installed as usr/include/sys/bar.h (the full path
in the file sections is appended to target)

If you want to install bar.h as /usr/include/bar.h, you would need two sections:




Assuming you can use $path in target, this can describe any scheme I
can think of, and I don't think it can be made simpler (I would be
happy to know of a simpler solution though).
