Packages with versions but no releases

[Brook Milligan <brook%nmsu.edu@localhost>]

I am making a package for software (rnaturalearthhires) that has version numbers but does not have any releases.  The only source seems to be a zip file with no version embedded in the name and the the project GitHub page lists 0 releases.

My question is what to use as the pkgsrc version.  Options I see are:

- Use the internal version.  This would seem to track what upstream is doing, but I am not sure what that number means relative to code updates and changes in the zip file.

- Use my download date.  This seems to be the pattern for other unversioned packages and will readily differentiate different copies of the zip file.  However, if upstream starts doing proper releases, we have the problem of which is earlier, a date or a version?

Thoughts?

Cheers,
Brook
