33 * About the different #defines that Motif gives us:
34 * All Motifs #define several values. These are the values in
35 * Open Motif 2.1.30, for example:
36 * #define XmVERSION 2
37 * #define XmREVISION 1
38 * #define XmUPDATE_LEVEL 30
39 * #define XmVersion (XmVERSION * 1000 + XmREVISION)
40 * #define XmVERSION_STRING "@(#)Motif Version 2.1.30"
41 *
42 * In addition, LessTif #defines several values as shown here for
43 * version 0.93.0:
44 * #define LESSTIF_VERSION 0
45 * #define LESSTIF_REVISION 93
46 * #define LesstifVersion (LESSTIF_VERSION * 1000 + LESSTIF_REVISION)
47 * #define LesstifVERSION_STRING \
48 * "@(#)GNU/LessTif Version 2.1 Release 0.93.0"
49 *
50 * Also, in LessTif the XmVERSION_STRING is identical to the
51 * LesstifVERSION_STRING. Unfortunately, the only way to find out the
52 * "update level" of a LessTif release is to parse the LesstifVERSION_STRING.
