prerequisites ============

1)see
  https://dev.lightning.community/guides/python-grpc/
  
rpc_pb2.py
put rpc_pb2.py in a python library path and update PYTHONPATH, e.g.
    export PYTHONPATH=${PYTHONPATH}:/srv/lib/python
    
2) requires python libraries: 
protobuf, grpcio, grpcio-tools          

channel_summary.py

* purpose:
    * display some information about connected channels. Can also be used to see total node capacity.
* requires:
    * LND  v0.11.0+  (at least for adjust_channel_fees, other scripts will work on earlier versions)
    * python3
* run with:

python3 channel_summary.py

adjust_channel_fees.py

* purpose:
    * automatically change channel fees based on: configured settings, current estimated basechain fees, and capacity of the channel (for example: if outgoing capacity is low, increase the fee)
* requires:
    * LND
    * python3
    * crontab
* run with:

python3 adjust_channel_fees.py

or run the same through crontab

get2_lowfee_nodes.py

* purpose:
    * retrieves a list of lightning nodes based on fee and capacity criteria specified in .py file, and determine distance in terms of number of hops, and capacity. NOTE: THIS CAN BE VERY SLOW
* requires:
    * LND
    * python3
* run with:

python3 get2_lowfee_nodes.py
