		USAGE:
		    installJRMC [[OPTION] [VALUE]]...

		    If no options (excluding -d or --debug) are provided installJRMC defaults to '--install repo'.

		OPTIONS
		    --install, -i repo|local
		        repo: Install MC from repository, updates are handled by the system package manager
		        local: Build and install MC package locally from official source release
		    --build[=suse|fedora|centos]
		        Build RPM from source DEB but do not install
		        Optionally, specify a target distro for cross-building (ex. --build=suse, note the '=')
		    --compat
		        Build/install MC locally without minimum dependency version requirements
		    --mcversion VERSION
		        Specify the MC version, ex. 30.0.51" (default: latest version)
		    --outputdir PATH
		        Generate rpmbuild output in this directory (default: ./output)
		    --restorefile RESTOREFILE
		        Restore file location for automatic license registration (default: skip registration)
		    --betapass PASSWORD
		        Enter beta team password for access to beta builds
		    --service, -s SERVICE
		        See SERVICES section below for a list of possible services to install
		      --service-type user|system
		          Starts services at boot (system) or at user login (user) (default: per service, see SERVICES)
		    --container, -c CONTAINER (TODO: Under construction)
		        See CONTAINERS section below for a list of possible services to install
		    --createrepo[=suse|fedora|centos]
		        Build rpm, copy to webroot, and run createrepo. 
		        Use in conjunction with --build=TARGET for crossbuilding repos
		        Optionally, specify a target distro for non-native repo (ex. --createrepo=fedora, note the '=')
		        --createrepo-webroot PATH
		            Specify the webroot directory to install the repo (default: /var/www/jriver)
		        --createrepo-user USER
		            Specify the web server user if it differs from $USER
		    --version, -v
		        Print this script version and exit
		    --debug, -d
		        Print debug output
		    --help, -h
		        Print help dialog and exit
		    --uninstall, -u
		        Uninstall JRiver MC, remove services, containers, and firewall rules (does not remove library files)

		SERVICES
		    jriver-mediaserver (default --service-type=user)
		        Enable and start a mediaserver systemd service (requires an existing X server)
		    jriver-mediacenter (user)
		        Enable and start a mediacenter systemd service (requires an existing X server)
		    jriver-x11vnc (user)
		        Enable and start x11vnc for the local desktop (requires an existing X server)
		        Usually combined with jriver-mediaserver or jriver-mediacenter services
		        --vncpass and --display are optional (see below)
		    jriver-xvnc (system)
		        Enable and start a new Xvnc session running JRiver Media Center
		        --vncpass PASSWORD
		            Set the vnc password for x11vnc/Xvnc access. If no password is set, installJRMC
		            will either use existing password stored in $HOME/.vnc/jrmc_passwd or use no password
		        --display DISPLAY
		            Display to use for x11vnc/Xvnc (default: The current display (x11vnc) or the
		            current display incremented by 1 (Xvnc))
		    jriver-createrepo (system)
		        Install hourly service to build latest MC RPM and run createrepo
