At my current employer we use Ant to execute our build scripts, and I need to add a target to our build.xml file that will start up 4 PHP scripts that are Gearman workers in the background, and then stop those scripts once the build is done.
I've looked at the 'parallel' and 'daemons' directives (is that the right word?) but I am not experienced enough with Ant to track down the info I'm missing on how to make sure the script runs in the background.
