longDescription =
'' 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.
