+      '' The POSIX 1003.1-2001 standard defines an application programming
+         interface (API) for writing multithreaded applications.  This
+         interface is known more commonly as pthreads.  A good number of
+         modern operating systems include a threading library of some kind:
+         Solaris (UI) threads, Win32 threads, DCE threads, DECthreads, or any
+         of the draft revisions of the pthreads standard.  The trend is that
+         most of these systems are slowly adopting the pthreads standard API,
+         with application developers following suit to reduce porting woes.
+
+         Woe32 does not, and is unlikely to ever, support pthreads natively.
+         This project seeks to provide a freely available and high-quality
+         solution to this problem.
