24 # normally a VersionHandler will take
25 # a to_version and yeild an iterator of
26 # "version sets" or something like that.
28 # A "version set" is basically an arrayref
29 # of "version numbers" (which we already know
30 # is vague as is.) Typically an call to a
31 # VH w/ a db version of 1 and a "to_version"
32 # of 5 will iterate over something like this:
38 # Of course rob wants to be able to have dep
39 # management with his versions, so I *think* his
40 # would work like this:
42 # to_version = 7, db_version = 1
47 # Because 7 depended on 5, 5 was installed first;
48 # note that this potentially never released module
49 # doesn't use version pairs, instead it just yeilds
50 # versions. Version pairs are too much work for users
51 # to have to deal with in that sitation. We may
52 # actually switch to this for other versioners.
54 # The upshot of all this is that the DeploymentMethod
55 # needs to be able to take an ArrayRef[VersionNumber],
56 # instead of just a pair of VersionNumber.
