The following options are supported:
-v, --version
Print the ConnMan-VPN software version and exit.
-h, --help
Print ConnMan-VPN's available options and exit.
-cfile, --config=file
Specify configuration file to set up various settings for ConnMan. If not specified, the default
value of /etc/connman/connman-vpn.conf is used. See connman-vpn.conf(5) for more information on
configuration file. The use of config file is optional and sane default values are used if config
file is missing.
-d [file[,...]], --debug[=file[,...]]
Sets how much information ConnMan-VPN sends to the log destination (usually syslog's "daemon"
facility). If the file options are omitted, then debugging information from all the source files
are printed. If file options are present, then only debug prints from that source file are
printed. Example:
connman-vpnd --debug=vpn/vpn-provider.c,vpn/vpn-config.c
-n, --nodaemon
Do not daemonize. This is useful for debugging, and directs log output to the controlling terminal
in addition to syslog.
