This is an attempt to acknowledge contributions to the garbage collector.
Early contributions also mentioned (duplicated) in ChangeLog file; details of
later ones should be in "git log".

Currently maintained by Ivan Maidanski.

HISTORY -

  Early versions of this collector were developed as a part of research
projects supported in part by the National Science Foundation
and the Defense Advance Research Projects Agency.

The garbage collector originated as part of the run-time system for
the Russell programming language implementation. The first version of the
garbage collector was written primarily by Alan Demers.  It was then refined
and mostly rewritten, primarily by Hans-J. Boehm, at Cornell U.,
the University of Washington, Rice University (where it was first used for
C and assembly code), Xerox PARC, SGI, and HP Labs.  However, significant
contributions have also been made by many others.
