  41  *
  42  * Belief is "Jim" would greatly benifit if Jim Internals where
  43  * documented in some way - form whatever, and perhaps - the package:
  44  * 'doxygen' is the correct approach to do that.
  45  *
  46  *   Details, see: http://www.stack.nl/~dimitri/doxygen/
  47  *
  48  * To that end please follow these guide lines:
  49  *
  50  *    (A) Document the PUBLIC api in the .H file.
  51  *
  52  *    (B) Document JIM Internals, in the .C file.
  53  *
  54  *    (C) Remember JIM is embedded in other packages, to that end do
  55  *    not assume that your way of documenting is the right way, Jim's
  56  *    public documentation should be agnostic, such that it is some
  57  *    what agreeable with the "package" that is embedding JIM inside
  58  *    of it's own doxygen documentation.
  59  *
  60  *    (D) Use minimal Doxygen tags.
  61  *
  62  * This will be an "ongoing work in progress" for some time.
