Where can i find "planet57.tools.buildmagic.task.Taskdef"

[allen]

I was trying to write my own JAASSecurityManager.
But when I'm trying to build the project. The build
file looks for
"planet57.tools.buildmagic.task.Taskdef".
Which I didn't get in the JBOSS source I downloaded
from JBOSS.org.
Can some one please tell me where I can find it.

The task is in jboss-all/tools/lib/buildmagic-tasks.jar
Use the build.sh or build.bat script to start the build process and ant is executed with a classpath that includes this task.
