+zita-ajbridge (ALSA <=> JACK bridge)
+
+zita-ajbridge provides two applications, zita-a2j and zita-j2a.  They
+allow using an ALSA device as a Jack client, to provide additional
+capture (a2j) or playback (j2a) channels.  Functionally these are
+equivalent to the alsa_in and alsa_out clients that come with JACK,
+but they provide much better audio quality. The resampling ratio will
+typically be stable within 1 PPM and change only very smoothly. Delay
+will be stable as well even under worst case conditions, e.g. the JACK
+client running near the end of the cycle.
+
+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.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
