What is Open Watcom?
Open Watcom is an effort to take the commercial Watcom compilers, and turn them into an Open Source Project. When Sybase realised that the Watcom C/C++ and Fortran compilers were no longer commercially viable, they searched around to find a solution for their existing customers. SciTech Software, a long time user of Watcom compiler products contacted Sybase about turning the compilers into an Open Source project, and hence the Open Watcom Project was born.
The Open Watcom products are the first and only commercial compilers to be open sourced and, with more than a million lines of source code, the Watcom products represent one of the largest pools of commercial source code of any type ever released under an Open Source license. Sybase is releasing the code under an Open Source license that complies with the Open Source Definition, published by the Open Source Initiative (http://www.opensource.org).
