"""Import twins (see aootest.twins): documents saved as ODF 1.2 and as ODF 1.3 from the same source by another producer, in the
plain and the extended flavour. Every document must load, and the two members of a pair must import alike. Two controls show
that the comparison can fail: an unchanged copy compares equal and a copy with one word changed compares different.

Needs a corpus (--twin-corpus or AOO_TWIN_CORPUS); without one the items skip. Differences that are understood are rows
in data/expect/twins.tsv."""
