# PX4 paramers processor (main executable file)
#
# This tool scans the PX4 source code for declarations of tunable parameters
# and outputs the list in various formats.
#
# Currently supported formats are:
#   * XML for the parametric UI generator
#   * Human-readable description in DokuWiki page format
#
# This tool also allows to automatically upload the human-readable version
# to the DokuWiki installation via XML-RPC.
