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".

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.
