-Pre-Alpha support for PLJava.
-
-!!! This code will not work against any released pljava version. See pljava developer list
-archive for discussion of the changes needed in pljava for this code to work. Let's hope all
-the fixes get into the next pljava release.
-
-Put pljava.jar and jts-1.7.1.jar into lib/ directory, then run ant.
