  62    (description
  63     "The Boehm-Demers-Weiser conservative garbage collector can be used
  64 as a garbage collecting replacement for C malloc or C++ new.  It allows
  65 you to allocate memory basically as you normally would, without
  66 explicitly deallocating memory that is no longer useful.  The collector
  67 automatically recycles memory when it determines that it can no longer
  68 be otherwise accessed.
  69
  70 The collector is also used by a number of programming language
  71 implementations that either use C as intermediate code, want to
  72 facilitate easier interoperation with C libraries, or just prefer the
  73 simple collector interface.
  74
  75 Alternatively, the garbage collector may be used as a leak detector for
  76 C or C++ programs, though that is not its primary goal.")
