Fedora Update Notification
FEDORA-2005-859
2005-09-19
---------------------------------------------------------------------

Product : Fedora Core 4
Name : pwlib
Version : 1.8.7
Release : 1.FC4
Summary : Portable Windows Libary
Description :
PWLib is a moderately large class library that has its genesis many
years ago as a method to produce applications to run on both Microsoft
Windows and Unix X-Window systems. It also was to have a Macintosh
port as well but this never eventuated. This version does not contain
any UI code.

It is supplied mainly to support the open H323 project, but that shouldn't stop
you from using it in whatever project you have in mind if you so desire.

---------------------------------------------------------------------
Update Information:

This is an upstream release (the last one in the 1.2 series)
of gnomemeeting and related libraries.
