+ Using any of the following switches will allow Libav to link to the
+ corresponding external library. All the components depending on that library
+ will become enabled, if all their other dependencies are met and they are not
+ explicitly disabled. E.g. --enable-libwavpack will enable linking to
+ libwavpack and allow the libwavpack encoder to be built, unless it is
+ specifically disabled with --disable-encoder=libwavpack.
+
+ Note that only the system libraries are auto-detected. All the other external
+ libraries must be explicitly enabled.
+
+ Also note that the following help text describes the purpose of the libraries
+ themselves, not all their features will necessarily be usable by Libav.
