version group lists the relative complement of the corresponding hint
file and the non-versioned requires: line.  It may be necessary to

Yeah, I guess we could generate requires: line in each version section now, and this might work with current setup. I don't think this did anything useful prior to [1] being fixed.


rename the requires: token to something else in order to ease parsing,
maybe something like requires+: to show that these are in addition to
the usual requires: line?
The libsolv branch implements per-version '[dD]epends:' headers as per [2] (which may also contain a version relation)
