I added the Maven assembly descriptor for the source distribution.
There is one issue. I didn't include uima-docbooks, so with the resulting source distribution you can build the jars/plugins but you can't build the actual binary distribution (if you run mvn assembly:assembly you get a file not found error). Should we include the docbooks sources in the source distribution? Even if we do that, there's still the matter of the 3rd-party JARs needed to run docbook - I'm not sure if we're allowed to bundle them in our distribution even if we wanted to. -Adam
