Each release of PmWiki has a $VersionNum variable, that is guaranteed
to always increase with each release.  (It doesn't always increase
by 1, but it always increases.)

The release number is 2xxxyyy, where xxx is the major revision number
and yyy is the minor revision number.  Thus 2.0.13 had a $VersionNum
of 2000013, 2.1.beta32 was 2000932, and 2.1.3 is 2001003.

So, if you need code that applies only to versions of PmWiki prior to
2.1.0, one can do:

    if ($VersionNum < 2001000) { ... }
