The version file of the python subpackage had to have the version set manually in setup.py due to the out-of-tree build where it was not possible to access the file VERSION. Manual update was error prone. Improve that by adding a separate file template that is finalized with the version during the configure phase. Then it's inclded in setup.py as it's in the same directory. There are two exceptions when the file is not required to run setup.py: - clean - allow running 'make clean' in partially configured directory - (no arguments) - show the help and commands In all other cases the file version.py must exist.
