Of the popular OSD compliant licenses, I like the MIT style license, but I wanted something that goes a little bit further in protecting the author's name and integrity of original source. (OSD #4 at http://opensource.org/osd.html) The OSD states that the license can restrict the distribution of modified works to be "patch files" but I have become convinced by discussions in the community that this is unworkable. So changing as little as possible, from the MIT license, I have the following. As a small developer/consultant, name and trademark recognition is very important, of course. That really ends up being the value I sell. The intent of the license is to allow distribution of unmodified software far and wide, but requires that modified versions be advertised and distributed using different names. If someone knows of a MIT-style license with a similar condition that already exists, please reply. I could not locate anything similar, and resorted to yet another open source license. With discussion and approval here, (and a better license name,) my hope is that many other developers will use the license when they wish to release open source software under a license that better protects name recognition. - - - - - - - - - - - - Copyright Notice - - - - - - - - - - - - Copyright 1999 Forrest J.
