+      This is a library to provide the GNU Pth API and thus a non-preemptive
+      threads implementation.
+
+      In contrast to GNU Pth is is based on the system's standard threads
+      implementation.  This allows the use of libraries which are not
+      compatible to GNU Pth.  Experience with a Windows Pth emulation showed
+      that this is a solid way to provide a co-routine based framework.
