I've just found out that links.csv is not complete, ie. it doesn't
cover all the pairs. For example, we have a Lojban sentence "lo purci
ka'e te djuno gi'e na ka'e se galfi .i lo balvi ka'e se galfi gi'e na
ka'e te djuno" and a Polish sentence "Przeszłość może być tylko
poznana, nie zmieniona. Przyszłość może być tylko zmieniona, nie
poznana." and they're not linked to each other, but they both are
linked to "The past can only be known, not changed. The future can
only be changed, not known.". I wonder if there's a rule that such
sentence always have a "common relative", it would certainly make
things easier. But I think that now using a database (maybe sqlite3)
would be necessary.
