 # threadweaver
 
+ThreadWeaver is a helper for multithreaded programming.  It uses a job-based interface to queue tasks and execute them in an efficient way.
+You simply divide the workload into jobs, state the dependencies between the jobs and ThreadWeaver will work out the most efficient way of dividing the work between threads within a set of resource limits.
