- Set the version of the program. The version is in free format, i.e. not
- necessarily in the @c x.y.z form but it shouldn't contain the "version" word.
+ Set the version of the program. The word "version" shouldn't be included
+ in @a version. Example @a version values: "1.2" and "RC2". In about dialogs
+ with more space set aside for version information, @a longVersion is used.
+ Example @a longVersion values: "Version 1.2" and "Release Candidate 2".
+ If @a version is non-empty but @a longVersion is empty, a long version
+ is constructed automatically, using @a version (by simply prepending
+ "Version " to @a version).
+
+ The generic about dialog and native GTK+ dialog use @a version only,
+ as a suffix to the program name. The native MSW and OS X about dialogs
+ use the long version.
