  75    (description
  76     "The Boehm-Demers-Weiser conservative garbage collector can be used
  77 as a garbage collecting replacement for C malloc or C++ new.  It allows
  78 you to allocate memory basically as you normally would, without
  79 explicitly deallocating memory that is no longer useful.  The collector
  80 automatically recycles memory when it determines that it can no longer
  81 be otherwise accessed.
  82
  83 The collector is also used by a number of programming language
  84 implementations that either use C as intermediate code, want to
  85 facilitate easier interoperation with C libraries, or just prefer the
  86 simple collector interface.
  87
  88 Alternatively, the garbage collector may be used as a leak detector for
  89 C or C++ programs, though that is not its primary goal.")
