# `bfa.py`
Script en Python que reporta distintos datos sobre la BFA
Este _script_ requiere Python 3 y la biblioteca web3 (que puede instalarse con `pip`).
Para funcionar requiere conocer el directorio donde está el _socket_ `geth.ipc` (asume que es `${BFANETWORKDIR}/node/geth.ipc` o, en su defecto `~/bfa/network/node/geth.ipc`), y el puerto RPC (asume que es el 8545). Ambos valores pueden especificarse en la línea de comandos.
También puede usarse como biblioteca. La clase BFA tiene un conjunto de métodos que permiten obtener información de un nodo `geth`.
