That indeed looks promissing.
Unfortunatelly one seems to have be a programmer to use osmosis. Every
problem is presented as a Java exception. Some of them contain at
least a faint idea of what could be wrong. But something like this
leaves me clueless:

java.lang.AbstractMethodError
  at com.bretth.osmosis.core.pipeline.common.TaskManagerFactory.createTaskManager(TaskManagerFactory.java:72)
 at com.bretth.osmosis.core.pipeline.common.Pipeline.buildTasks(Pipeline.java:50)
 at com.bretth.osmosis.core.pipeline.common.Pipeline.prepare(Pipeline.java:112)
 at com.bretth.osmosis.core.Osmosis.run(Osmosis.java:79)
 at com.bretth.osmosis.core.Osmosis.main(Osmosis.java:30)

Happens as soon I'm adding the --tt option, regardless with what arguments.
