  48    (description
  49     "The Boehm-Demers-Weiser conservative garbage collector can be used
  50 as a garbage collecting replacement for C malloc or C++ new.  It allows
  51 you to allocate memory basically as you normally would, without
  52 explicitly deallocating memory that is no longer useful.  The collector
  53 automatically recycles memory when it determines that it can no longer
  54 be otherwise accessed.
  55
  56 The collector is also used by a number of programming language
  57 implementations that either use C as intermediate code, want to
  58 facilitate easier interoperation with C libraries, or just prefer the
  59 simple collector interface.
  60
  61 Alternatively, the garbage collector may be used as a leak detector for
  62 C or C++ programs, though that is not its primary goal.")
