You're not supposed to have to worry about buffer sizes in Python. It
should just give you the whole thing.
inlen and outlen are supposed to be
independent.
They aren't independent, though, because you need to know how long to
make the output buffer so as to fit the entire translated input buffer.
Unless you allocate a ridiculously huge output buffer all the time (and
check that your input buffer never exceeds this), you have to try to
guess how big to make outlen based on inlen.
How does liblouisxml determine the size of outlen?
