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

		    If no options (besides -d) are provided, the script will default to '--install repo'.

		OPTIONS
		    --install, -i repo|rpm|deb
		        repo: Install MC from repository, updates are handled by the system package manager
		        rpm: Build and install RPM locally (RPM-based distros only)
		            deb: Download and install offcial MC package locally (useful with --compat flag for older distros)
		    --build
		        Build RPM from source DEB but do not install. Optional TARGET parameter enables RPM crossbuilding (ex. 'opensuse', 'fedora', 'centos')
		    --target opensuse|fedora|centos
		        Cross-build RPM or createrepo for target distro
		    --mcversion VERSION
		        Specify the MC version, ex. "28.0.94" (Default: latest)
		    --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: boot)
		    --container, -c CONTAINER (TODO: Under construction)
		        See CONTAINERS section below for a list of possible services to install
		    --createrepo
		        Build rpm, copy to webroot, and run createrepo. Use in conjunction with --build=TARGET for crossbuilding repos
		        --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
		    --compat
		        Build/install RPM without minimum library specifiers
		    --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, and remove firewall rules (does not remove library files)

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

		CONTAINERS (TODO: Under construction)
		    mediacenter-xvnc
		    createrepo
