 NOTE: mpv has several optional features that are automatically enabled if the
-required libraries are present at configure time. This package does not include
-any of the optional features as dependencies by default (but it does add depends
-for whatever is linked against when building the package). If you want to use
-any optional features that require libraries you don't currently have installed,
-please install the relevant libraries and rebuild the package. A frequently
-desired optional feature is Lua support, which is necessary for the on-screen
-controller "GUI", youtube-dl integration, and other extension scripts. Lua
-support can be provided by lua52 or luajit.
