According to the project homepage at
http://infozip.sourceforge.net/Zip.html, the version is really named
3.0. This is also how it's called inside the zip30.ann file in the
source code, which says "We have posted Zip 3.0, July 5th 2008".
So the fact that the tarball is named zip30.tgz is just because
upstream wanted to avoid having two dots (perhaps by habit of the old
DOS 8.3 file name limitation ?).
The version is also named "3.0" in the SourceForge RSS at [0] that
release-monitoring.org is using for this package [1]. Therefore, by
using "3.0" as the version, we will match the version known by
release-monitoring.org.
Of course the tarball name is still zip30.tgz so we tweak the
ZIP_VERSION value appropriately.
