+Jack Meter is a basic console based DPM (Digital Peak Meter) for JACK. The
+author wrote it for quickly checking remote signal levels, without having
+to run X11 to use a pretty graphical meter such as meterbridge.
+
+Note: the package is called jackmeter, but the actual binary is called
+jack_meter (with underscore).
+
+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 ':'.
