+%description
+Grand Central Dispatch (GCD or libdispatch) provides 
+comprehensive support for concurrent code execution on 
+multicore hardware.
+
+libdispatch is currently available on all Darwin platforms. 
+This project aims to make a modern version of libdispatch 
+available on all other Swift platforms. To do this, we will 
+implement as much of the portable subset of the API as 
+possible, using the existing open source C implementation.
+
+libdispatch on Darwin is a combination of logic in the xnu 
+kernel alongside the user-space Library. The kernel has the 
+most information available to balance workload across the 
+entire system. As a first step, however, we believe it is 
+useful to bring up the basic functionality of the library 
+using user-space pthread primitives on Linux. Eventually, a 
+Linux kernel module could be developed to support more 
+informed thread scheduling.
