- * 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.
