Yet Another Application Framework is a C++ application framework that simplifies the creation of Macintosh, Microsoft Windows and X Windows applications. YAAF includes a library, a "Constructor", a set of tools called "RCompile", source code, utilities and examples. "Constructor&quot\; is the application's dialog and window editor. "RCompile&quot\; is a set of tools that allow resources to be compiled to a C++ source file or linked to a Unix YAAF application. Source code and libraries for the Macintosh and RedHat Linux for Intel are also included. Please note that as this is an alpha version of the framework and some features may be incomplete or buggy.
