It doesn't implement any comparison, but it does check for valid versions
according to Section 5.6.12 in the Debian Policy Manual. Since splitting
the version into epoch, upstream_version, and debian_revision components is
pretty much free with the validation, it sets those fields as properties of
the object, and sets the raw version to the full_version property. A
missing epoch or debian_revision results in the respective property set to
None. Setting any of the properties results in the full_version being
recomputed and the rest of the properties set from that.
It also implements __str__, just returning the raw version given to the
initializer.

a1 Converts source to a stream of patches.
Patches are triples of line indexes:
- number of the first line to be replaced
- one plus the number of the last line to be replaced
- list of line replacements
This is enough to model arbitrary additions, deletions and
replacements.
