Building/installation:
sudo python setup.py install
If you prefer to have it cleanly removable, install checkinstall and run
sudo checkinstall python setup.py install
Alternatively, just run 'pip install --user -e ./' or 'pip3 install --user -e ./'
depending on your python version.

Use
There are currently following scripts in this package:
osmotestconfig.py - test that apps start/write with example configs
soap.py - implementation of SOAP <-> Ctrl proxy implemented on top of Twisted
osmo_interact_vty.py - pipe stdin/stdout to a VTY session
osmo_interact_ctrl.py - pipe stdin/stdout to a CTRL port
osmo_verify_transcript_vty.py - VTY testing by VTY session screen dumps
osmo_verify_transcript_ctrl.py - CTRL testing by CTRL session script files
osmodumpdoc.py - dump documentation, superseded by osmo_interact_vty.py -X
osmotestvty.py - test vty operations, superseded by osmo_verify_transcript_vty.py

Each of these scripts imports a project-specific osmoappdesc.py,
which provides information about the available apps, configs, vty ports, etc.

Run the scripts with osmoappdesc.py in the current directory (preferred)
or with -p <the directory containing osmoappdesc.py>.
Remember that osmoappdesc.py may contain relative paths.

Example:
After install osmodumpdoc for openbsc's apps can be run by:
cd <your_source_dir>/openbsc/openbsc && osmodumpdoc.py

Libraries:
osmopy/osmoutil.py - code that's shared between the scripts
osmopy/osmo_ipa.py - generic implementation of IPA and Ctrl protocols in python
twisted_ipa.py - implementation of IPA and Ctrl protocols on top of Twisted framework
osmopy/osmo_interact/{vty,ctrl}.py - general interactions with VTY and CTRL ports
osmopy/obscvty.py - connect to a vty, superseded by osmo_interact/vty

obscvty.py may be of general use. osmoutil.py probably isn't.
