Open Source
From DataFlex Wiki
Open-source software is computer software for which the source code is available under a license (or arrangement such as the public domain) that meets the Open Source Definition. Open Source Software is commonly associated with freeware even though not all freeware is open source and open source software does not have to be free (as in zero price). In the words of Richard Stallman, founder of the Free Software Foundation, open source software is "free as in speech, not free as in beer".
In the Dataflex world Open Source products such as VDF Query and The Hammer are commonly used by developers.
There are many Open Source programs available in a wide range of languages, many of which can be found on the popular Sourceforge site.
