33 * Revision 1.5 1999/05/21 22:14:30 mdw
34 * Take advantage of the new dynamic string macros.
36 * Revision 1.4 1999/05/19 19:02:17 mdw
37 * Aesthetic changes: fix spelling of `initialize'; use uppercase token
38 * constants; abandon old double-underscore convention for internal
39 * functions and variables.
41 * Revision 1.3 1999/05/06 19:51:35 mdw
42 * Reformatted the LGPL notice a little bit.
44 * Revision 1.2 1999/05/05 18:50:31 mdw
