+FAAC is an Advanced Audio Coder (MPEG2-AAC, MPEG4-AAC).
+The goal of FAAC is to explore the possibilities of AAC and exceed
+the quality of the currently best MP3 encoders.
+
+faac comes with its own version of libmp4v2, but if you use it, you have to
+uninstall faac everytime you want to update it, as faac would otherwise
+detect the already installed libmp4v2 and build against it. Then, when you
+upgrade to the new package, it doesn't have the included libmp4v2, because
+it was part of the old package, so faac is linking to a nonexistent library
+after the upgrade. Long story short, we strongly recommend using the
+external libmp4v2 (available from SlackBuilds.org); just make sure it is
+installed when you configure faac, and it will be detected automatically.
+
+NOTE: If you have installed faac < 1.26-i486-2_SBo, make sure to remove it
+before either installing libmp4v2 or running the new SlackBuild.
