C++ Interface to the Boehm Collector
John R. Ellis and Jesse Hull
Last modified on Mon Jul 24 15:43:42 PDT 1995 by ellis
This interface provides access to the Boehm collector. It provides
basic facilities similar to those described in "Safe, Efficient
Garbage Collection for C++", by John R. Elis and David L. Detlefs
(ftp.parc.xerox.com:/pub/ellis/gc).
