# PanOS API-based model for Oxidized

# The API-based model produced an XML configuration file that can actually be
# restored as a configuration backup. Make sure to use the "http" input for
# this module.

  # configuration file format uses XML. It is required to parse API
  # responses, as well as to pretty-print the configuration XML file
  # when saving it.
