Ant 1.3 sequence of tasks but would like concurrent?

[Nasgowitz, Mark (MED, GEMS-IT)]

Currently I run a sequence of different clearcase builds on different
Unix boxes using an ant script on a NT box to kick them off. Once all
tasks are done ant emails messages and ftps all results to a common
site. The problem is that the whole process takes a long time(++hours)
to finish all tasks. Since I run each build on different Unix boxes I
would like to kick them all off at the same time then build the result
data as each build finishes. 

Is there a task that can be used (<antcall>, <ant> or <??>) but not wait
for the task to finish?

I would like to a void using ant to call a perl script that forks a call
to the ant build script.

suggestions??

Thanks,
Mark
