This is a set of test scripts for osmocom projects.

Currently, it's tested on openbsc and osmo-pcu.
Scripts: osmotestvty.py osmodumpdoc.py osmotestconfig.py
The scripts are designed to be run from make check,
but can be run independently as well.
As a general rule, run them in the top dir of a project.
