+japa (audio spectrum analyser for jack-audio-connection-kit)
+
+Japa (JACK and ALSA Perceptual Analyser), is a 'perceptual' or
+'psychoacoustic' audio spectrum analyser. Possible uses include spectrum
+monitoring while mixing or mastering, evaluation of ambient noise, and
+(using pink noise), equalisation of PA systems.
+
+By default, the package is built with '-march=native'. If you need a
+generic package that can be installed on any Slackware machine with the
+same ARCH as the build host, set FORCE_SLACK_CFLAGS=yes in the script's
+environment.
+
+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.
