I've been working on re-organizing the build system for the TEI Oxygen plugin, using ant, so that the four different build scenarios we need to handle are all easily run from a single source, and there's more support for people doing release-building. This has required learning quite a bit more about ant than I knew before, all of which is very useful. I'm 90% done with this, although obviously some bits are untested (uploading to SourceForge, uploading to tei-c).
