#/bin/bash

# Starts a Hydrabadger node
# =========================
#
# Optional environment variables:
#
# * HYDRABADGER_LOG_ADDTL:
#
#   Appends additional logging args (debug, trace, filters, etc.).
#
# * HYDRABADGER_RELEASE:
#
#   Builds in debug mode if `HYDRABADGER_RELEASE` == `0` or `false`.
#   Slows down output and makes reading log easier.
