jwe,
The EDITION number used in the documentation is the same as the VERSION
number according to the documentation for Automake:
|EDITION|
|VERSION|
Both of these macros hold the version number of your program. They
are kept separate for clarity.
Since we want EDITION to be just the base number (4, not 4.3.90) should
be post-process the generated version-octave.texi file with sed, or
should we just hardcode the EDITION number in the title page of
octave.texi and bump it when we make major releases (which isn't that
often).
