Dunno, it works for me. All I know is that up to now I've always been
*very* glad to get rid of any userinterface in front of a parser tool/suite
and exchange it for the underlying commandline tools.

The whole manual could use a major rework.

There's ParseView for java mode but nobody seems interested in maintaining
it. The most up to date version (for 2.7.1?) of it can be downloaded from
