30 /*----- Revision history --------------------------------------------------*
33 * Revision 1.7 1999/11/21 13:01:39 mdw
34 * Allow more characters to start words in test vector files.
36 * Revision 1.6 1999/11/16 15:03:23 mdw
37 * Mark test types as constant.
39 * Revision 1.5 1999/05/21 22:14:30 mdw
40 * Take advantage of the new dynamic string macros.
42 * Revision 1.4 1999/05/19 19:02:17 mdw
43 * Aesthetic changes: fix spelling of `initialize'; use uppercase token
44 * constants; abandon old double-underscore convention for internal
45 * functions and variables.
47 * Revision 1.3 1999/05/06 19:51:35 mdw
48 * Reformatted the LGPL notice a little bit.
50 * Revision 1.2 1999/05/05 18:50:31 mdw
51 * Change licensing conditions to LGPL.
