 NOTE: this package conflicts with jack-audio-connection-kit: install
 only one of the two.
 
+This package uses POSIX filesystem capabilities to execute with
+elevated privileges (required for realtime audio processing). This
+may be considered a security/stability risk. Please read
+http://www.slackbuilds.org/caps/ for more information. To disable
+capabilities, pass SETCAP=no to the script.

 Optional dependencies are celt, libffado and opus.
