Hi Christian,
Sure, that seems easy enough to implement. I'll get that
feature up and running soon.
Yes, most of the functions are based on title, I did that because I didn't
find any difference between the two when I browsed around 5-6 ZIM files. But
as you say, I'll add their URL counterparts as well. I'll also add the
documentation-gen module to the repository.
Hmm, I'm not subscribed to that mailing list. I'll go through the thread
that discusses performance.
