* Revision 0.11 1992/04/13 11:40:53 dennisg
* Check in after array version of run-time works.
* Expect more changes as hash version and other changes are made.
*
* Revision 0.10 1991/12/31 20:16:08 dennisg
* Deleted index variable stuff. Index variables are a hack to the language.
* Cleaned up some documentation.
*
* Revision 0.9 1991/12/10 12:04:22 dennisg
* Cleaned up file format for a distribution.
*
* Revision 0.8 1991/12/01 01:29:29 dennisg
* modified to remove changes previously made to
* implement posing. posing just got easy.
*
* Revision 0.7 1991/11/29 22:00:10 dennisg
* modified to implement set functions.
*
* Revision 0.6 1991/11/29 20:02:01 dennisg
* fixed several const decls. bozo.
*
* Revision 0.5 1991/11/29 00:24:14 dennisg
* many changes including posing, things to make the compiler
* happier, structure changes, and things to make it play better.
*
* Revision 0.4 1991/11/19 12:37:49 dennisg
* changed typedef and struct decls.
* the run-time was changed and those decls changed too.
*
* Revision 0.3 1991/11/16 15:57:35 dennisg
* changed the defs for class structures for new implementation of run-time.
* changed def of SEL back to its original type.
*
* Revision 0.2 1991/11/07 22:31:42 dennisg
* added copyleft.
*
* Revision 0.1 1991/10/24 00:19:24 dennisg
* Initial check in. Preliminary development stage.
*
