# PX4 airframe config processor (main executable file)

# This tool scans the PX4 ROMFS directory for declarations of airframes
#
# Currently supported output formats are:
#   * XML for the parametric UI generator (Used in QGC)
#   * Markdown for the PX4 User guide (https://github.com/PX4/PX4-user_guide)
