+# -- PATENT ALERT! --
+# The ffmpeg in HandBrake can be built with AAC audio encoder (used in MP4)
+# but this library is 'contaminated' with patents from Apple etc.
+# In addition, the FDK AAC encoder has a GPL-imcompatible license so
+# ffmpeg forbids redistribution of binaries containing that encoder.
+# You can build these patended algorithms into ffmpeg, and if you are an
+# ordinary end user, no one will bother you for using them.
+# For the binaries based on this SlackBuild that I distribute, it is a
+# different story. I am not allowed to distribute binary packages that
+# incorporate non-free code. So here you go. My Slackware package was built
+# with "USE_PATENTS=NO" i.e. without using the aac libs.

 # Do you want to compile the GTK+3 based GUI (ghb) or just HandBrakeCLI ?
 # By default the script compiles the GUI but that will fail if your GTK+3
