+    script to cycle profiles with a keybind, accomplished through script messages
+    available at: https://github.com/CogentRedTester/mpv-scripts
+    syntax:
+        script-message cycle-profiles "profile1;profile2;profile3"
+    You must use semicolons to separate the profiles, do not include any spaces that are not part of the profile name.
+    The script will print the profile description to the screen when switching, if there is no profile description, then it just prints the name
