39 *--- Inline Header File Documentation ---
40 * [By Duane Ellis, openocd@duaneellis.com, 8/18/8]
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.
46 * Details, see: http://www.stack.nl/~dimitri/doxygen/
48 * To that end please follow these guide lines:
50 * (A) Document the PUBLIC api in the .H file.
52 * (B) Document JIM Internals, in the .C file.
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.
60 * (D) Use minimal Doxygen tags.
62 * This will be an "ongoing work in progress" for some time.
