draft

Many people have contributed to the GRASS GIS. Without any one of them, GRASS would not exist in its current form. 

The authors of the individual programs are listed at the end of their manual page in GRASS users manual, however, numerous authors of bug fixes and enhancements as well as people who have been working on coordination, integration, documentation and testing are not mentioned. Therefore, this page  is an attempt to acknowledge those who contributed to GRASS development. 

Please allow us to extend our most cordial thanks to all of you. If you contributed to GRASS at any point during it's existence, please let us know your name and e-mail address so we can add your name here
