There are several reasons.

1. BrLAPI currently doesn't allow you to use the BRLTTY contraction support
directly from applications, as I understand it.

2. Liblouis is (or used to be) more advanced than the code built into BRLTTY;
basically, BRLTTY includes an old version of what is in Liblouis, so for
handling mathematics and other complex content, it's better to be using the
Louis library.

I suggested once on the BRLTTY list that they should just use liblouis and
remove the older code from BRLTTY, but there were good reasons for not doing
that, which are related to changes made in the BRLTTY version.

I am sure that all of the above will be sorted out eventually. We really need
to have only one library and one set of tables.
