Any guesses on how tightly version numbers should match?

[Diane Trout]

Hello,

I was working on updating the Debian package of geiser and sometime
between now and the 0.10, the language specific support modules got
split out into separate modules.

I was wondering how closely the geisier and gesier-language package
versions should match? Do they need to exactly match or do you think
there's a reasonable chance close versions could work together?

Thanks
