This is where the meat is. Basically the data_files list must
now be a list of tuples of 3 entries. The first
entry is one of 'base', 'platbase', etc, which indicates which
base to install from. The second entry is the path to install
too. The third entry is a list of files to install.

if lof[0]:
base = getattr(self, 'install_' + lof[0])
base = getattr(self, 'install_base')
dir = convert_path(lof[1])
if not os.path.isabs(dir):
dir = os.path.join(base, dir)
elif self.root:
dir = change_root(self.root, dir)
files = lof[2]
if len(files) == 0:
# If there are no files listed, the user must be
# trying to create an empty directory, so add the the
# directory to the list of output files.
# Copy files, adding them to the list of output files.
for f in files:
f = convert_path(f)
(out, _) = self.copy_file(f, dir)
