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

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

		OPTIONS

		    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. "$MC_VERSION" or "${MC_VERSION%%.*}"
		  --arch VERSION
		    Specify the target MC architecture, ex. "amd64", "arm64", etc (default: host)
		  --mcrepo REPO
		    Specify the MC repository, ex. "bullseye", "bookworm", "noble", etc (default: auto)
		  --outputdir PATH

		  --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
		  --no-update
		    Disable automatic installJRMCself-update
		  --uninstall, -u
		    Uninstall JRiver MC, remove services, containers, and firewall rules (does not remove library files)
		  --yes, -y, --auto
		    Assume yes response to questions
		  --version, -v
		    Print this script version and exit
		  --debug, -d
		    Print debug output
		  --help, -h
		    Print help dialog and exit

		SERVICES
		  jriver-mediaserver (default --service-type=user)
		    Enable and start a mediaserver systemd service (requires an existing X server)

		    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
