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