 %description
-Greenlets are lightweight coroutines for in-process concurrent programming.
+The greenlet package is a spin-off of Stackless, a version of CPython
+that supports micro-threads called "tasklets". Tasklets run pseudo-concurrently
+(typically in a single or a few OS-level threads) and are synchronized
+with data exchanges on "channels".
