+This script will search the plex.tv download site for a download link
+and if it is newer than the currently installed version the script will
+download and optionaly install the new version.
+
+OPTIONS:
+   -u      PlexPass username
+             If -u is specified without -p then the script will
+             prompt the user to enter the password when needed
+   -p      PlexPass password
+   -c      PlexPass user/password file
+             When wget is run with username and password on the
+             command line, that information is displayed in the
+             process list for all to see.  A more secure method
+             is to create a file readable only by root that is
+             formatted like this:
+               user={Your Username Here}
+               password={Your Password Here}
+   -l      Local file to install instead of latest from Plex.tv
+   -d      download folder (default /tmp) Ignored if -l is used
+   -a      Auto Update to newer version
+   -f      Force Update even if version is not newer
+   -r      Remove update packages older than current version
+             Done before any update actions are taken.
+   -v      Verbose
+   -n      Use normal version (not PlexPass) version
