These XML config fragments constitute the bulk of what can
be shared between different apps built on the Synthesis engine.
The rest is very app specific (like datastores, paths, version, etc).
The import-synthesis-xml.sh script mirrors all changes made to
syncclient_sample_config.xml on the libsynthesis master branch
on a "synthesis" branch, with the file itself moved into src
alongside our own syncevolution.xml.
