GRASS List of Authors
=========================

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

The authors of the individual programs are listed at the end of their
manual page in the GRASS users manuals or in the source code. However,
numerous authors of bug fixes and enhancements as well as people who
have been working on coordination, integration, translation,
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 its existence, please let
us know your name and e-mail address so we can add your name.

GRASS 5 and 6 major project contributors
----------------------------------------

Thus we must thank and credit the members of the 5.0 + 6.x core
development team, listed below, as many are still active in the
project and GRASS GIS owes much of itself to the generosity of their
bright minds.

GRASS 6.0 was made up of entirely new code for much of the vector and
database management subsystems. The raster, display, and projection
subsystems are largely directly inherited from GRASS 5.4 without change.
The core GIS, GUI, and build subsystems are a hybrid of old and new code.



GRASS 1 to 4 major project contributors
---------------------------------------

Active parts of the program have authors dating back to GRASS's
inception in 1982. Please check the GRASS GIS credits list at:
