+SUMMARY = "A garbage collector for C and C++"
+
+DESCRIPTION = "The Boehm-Demers-Weiser conservative garbage collector can be\
+ used as a garbage collecting replacement for C malloc or C++ new. It allows\
+ you to allocate memory basically as you normally would, without explicitly\
+ deallocating memory that is no longer useful. The collector automatically\
+ recycles memory when it determines that it can no longer be otherwise\
+ accessed.\
+ The collector is also used by a number of programming language\
+ implementations that either use C as intermediate code, want to facilitate\
+ easier interoperation with C libraries, or just prefer the simple collector\
+ interface.\
+ Alternatively, the garbage collector may be used as a leak detector for C\
+ or C++ programs, though that is not its primary goal.\
+ Empirically, this collector works with most unmodified C programs, simply\
+ by replacing malloc with GC_malloc calls, replacing realloc with GC_realloc\
+ calls, and removing free calls."
