lxa5-bare-bones

Without any Python packaging elements, this repo is the "bare bones" version of Linguistica 5. It branches out from the commit ad1263a92bf95c549d678c7355a4a2c6dad2ed8d of the linguistica-uchicago/lxa5 repo.

TODO: Need to remove the linguistica namespace in all .py files, and need to move everything under the linguistica/ to the repo top level, so that running python __main__.py or equivalent would work
