++ These libraries have been compiled as drop-in replacements

++ .LP
++ The C++ header file, "gc_cpp.h",

++ necessary for C++ programs, to obtain the appropriate
++ definitions of the
++ .I new
++ and
++ .I delete
++ operators.
++ The comments in both of these header files presently

++ for the package than this man page;
++ look there for more information.

++ Both libraries are compiled without (explicit) support
++ for the experimental
++ .I gc
++ extension of
++ .I g++.
++ This may or may not make a difference.

+Garbage collection and memory leak detection for C and C++.

devel/boehm-gc/pkg-descr

+The Boehm-Weiser garbage collection package, for C and C++ -
+garbage collection and memory leak detection libraries.
+
+A garbage collector is something which automatically frees malloc'd
+memory for you by working out what parts of memory your program
+no longer has pointers to.  As a result, garbage collectors can also
+inform you of memory leaks (if they find memory they can free, it means
+you have lost all of your pointers to it, but you didn't free it).
+
+This package has two libraries and some include files:
+libgc.a - a garbage collection library, replaces malloc/free/new/delete/etc
+    with versions that do automatic garbage collection
+libleak.a - a leak detection library, which is just libgc.a compiled with
+    different switches.
+
+C programs may be linked against either of these, and should run (with
+GC or leak detection) without change.  C++ programs must include a header
+to use garbage collection, though leak detection should work without
+such source code modifications.  See the man page and header files.
+
+-- Mike McGaughey <mmcg@cs.monash.edu.au>
+
+ps: garbage collection is addictive.
