Eek - I didn't realise the jar task just used jar itself. I'd have
thought it would all be coded up. I'll have to investigate further.

Possibly... I got rather confused with that part of the thread when it
started spiralling. It's definitely too close to bed time to work it all
out now.

The documentation doesn't quite suggest that as far as I can see - it
looks like it's just for merging existing jar files into a new one,
rather
than updating an existing one.
Possibly even just a task which did things the inelegant way internally
(the rename/re-jar/delete way) would be worth investigating - that
shouldn't
take too long to knock up (I'd hope - I haven't investigated any
macro-like
capabilities within ant yet). Anything to avoid having to write that
long
kludge out several times would help.
