Wildcard Tasker Resources

A tasker can also offer resources that contain a wildcard. The wildcard is '*' and can be used instead of the name or the type. Legal values for wildcard resources are:


Wildcard	Description
*	Matches all resources that have no type
:	Matches all resources
*:hsim	Matches all resources with name "hsim"
License:*	Matches all resources of type "License"
JobType:*	Matches all resources of type "JobType"

These resources are particularly useful for Indirect Taskers, which are used to transfer jobs from FlowTracer to Accelerator.
