# NAME
# custodian-enqueue - Parse tests from a file and enqueue them.
#
# SYNOPSIS
# custodian-enqueue [ -h | --help ]
# [ -m | --manual]
# [ -q | --queue NAME]
# [ -f | --file FILE]
# [ -d | --dump ]
# [ | --test ]
#
# OPTIONS
#
# -h, --help Show a help message, and exit.
#
# -m, --manual Show this manual, and exit.
#
# -d, --dump Dump the parsed tests to the console; don't insert in the queue.
#
# --test Test the parsing of the given file, alert on errors.
#
# -f, --file FILE Parse the given configuration file.
#
#
#
# ABOUT
#
# This tool reads a single configuration file and parses it into a
# series of network & protocol tests. These tests are then stored in
# a queue from which workers can retrieve and execute them.
#
# The dequeing process may occur up numerous other hosts
#
# CONFIGURATION FILE
#
# The configuration file is 99% compatible with that used in the tool
# custodian replaces.
