We've now written XSLT to patch the four config files for Cocoon and exist automatically, and that seems to be working, as well as using patch to patch the build.properties file. The whole automated system is running very well, but the results currently don't have a working JNLP -- don't know why, but perhaps something in the trunk has changed which has broken it. I'll try a fresh build with a completely new checkout tomorrow. This is really tiring, but we'll eventually get there...
