Application Development with Harbour

Cross platform application development is a challenging task. Many script languages are designed to run on interpreters that are available for many operating systems. The harbour-project has a different approach. It is capable of compiling native applications for many operating systems like MS-DOS, Windows (32 & 64), Windows CE, Pocket PC, OS/2, GNU/Linux and Mac OS X and you only write one source code. The Harbour Project is a Free Open Source Software effort to build a multiplatform Clipper language compiler.
