There is a fairly popular de-facto standard for versioning: semver. Yes,
it is incompatible with Debian (and I guess FreeBSD) but you can make
it compatible by just changing one character ("-" -> "~").

Since apparently a version naming scheme is needed, does anyone have
a good reason NOT to use a standard that's easily adaptable to several
popular distributions?
