I asked the same question just recently - and it = turns out there
isn't really a nice way round it. You can do = something like:

but it isn't terribly satisfactory. As this is at = least the third time
it's been asked (and is actually all that's really = keeping me from using
Ant
for the build procedures at work), I may have a look = into it and see
whether
I can't come up with a patch...
