# into existing zoneminder systems. This script also provides a way to export
# ptz camera controls & camera presets from an existing zoneminder system into
# a sql file, which can then be easily imported to another zoneminder system.

PARAMETERS:
--export - Export all camera controls and presets to STDOUT.
Optionally specify a control or preset name.
--import [file.sql] - Import new camera controls and presets found in
zm_create.sql into the ZoneMinder dB.
Optionally specify an alternate sql file to read from.
--overwrite - Overwrite any existing controls or presets.
with the same name as the new controls or presets.
--topreset id - Copy a monitor to a Camera Preset given the monitor id.
--noregex - Do not try to find and replace fields such as usernames,
passwords, ip addresses, etc with generic placeholders
when converting a monitor to a preset.
--help - Print usage information.
--user=<dbuser> - Alternate dB user with privileges to alter dB.
