+ngjackspa (JACK host for LADSPA plugins)
+
+ngjackspa is a set of simple user interfaces that host a LADSPA plugin,
+providing JACK ports for its audio inputs and outputs, and dynamic setting
+of its control inputs. Additionally, the plugin controls can be exported
+to or controlled by control voltages on standard JACK audio ports.
+
+By default, the Qt user interface is built, and the gtkmm UI is disabled.
+To disable Qt, set QT=no in the script's environment. To enable gtkmm,
+set GTKMM=yes (this will require gtkmm to be installed, of course).
+
+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.
