  I'd like to create a list of projects that use or have used ZThreads; many
  of you have already contacted me and I am very grateful for that. I think it
  might be intresting for other people to see who as used ZThreads and for what
  so if you'd like to get your project listed send me some mail.

OVERVIEW:

    Concurrency has become an increasingly important aspect of software today. 
  The ZThread package is an advanced object-oriented, cross-platform, C++ 
  threading and synchronization library that has been designed and implemented 
  by the author and released under the GPL. It provides a high level 
  abstraction of the native threading mechanisms to offer a great deal of 
  flexibility and control. 

    This software features interruptible Thread and Runnable objects for C++, 
  control objects and implementations of concurrency design patterns. This 
  includes semaphores, mutexes, condition variabes as well as other more 
  complex components.

    Existing threading APIs do not provide a consistent and portable means for 
  exercising control over concurrently executing software. Thread cancellation and termination is 
  one example of this complexity. ZThreads includes an elegant method of 
  safely terminating threads without the complications of using cancellation 
  handlers or other similar constructs. 

    This is a platform independent architecture that was designed by the 
  author. Implementations have been provided for POSIX and Win32 platforms. 
  Building this library was quite different for POSIX than it was for Win32 
  due to the nature of the functionality each platform naturally provides; 
  each platform had strong and weak points. They were used to create the most 
  flexible and efficent abstraction possible. 

    The result is an excellent software layer on which to build mutlithreaded 
  code. 

LICENSE:				

	This source has been released under the LGPL. See LGPL.TXT for
  details regarding the license. You can you use this in closed source
  projects, contact me if you need to discuss a different licencing.  

COMPILING:

    ZT_POSIX, ZT_WIN32 should be defined to specific what platofrm your building
  on this. This is mainly so the right modifiers can be placed on class and 
  function definitions to export things from a DLL properly if your using the
  WIN32 implementation. If you leave these flags out ZThreads will try to guess.

    See BUILDING for more details.

DISTRIBUTION:
  
    If you package ZThreads with your application, that fine with me. You can
  do it in binary form or source form. Don't forget to mention somewhere in
  your documents the LGPL & the credits for the library.

    In the case of development or source release it would be nice if you 
  pointed the other developers to the source distribution of this library.
  This keeps things a little more centralized & current; as well as giving
  this library a little more exposure.

**  

   If you find this library useful, or you release something that uses it, 
  please let me know. I'd be curious to see how people have made use of
  this library.

NOTES:

  Please report bugs to me via email

HISTORY:

  So far, this library has been tested on MacOS X, Linux, Tru64 Unix, Win95, Win98, 
  WinNT, Win2k, SunOS, Solaris and FreeBSD.
