+caps (audio plugin suite for LADSPA)
+
+CAPS, the C* Audio Plugin Suite, is a collection of refined LADSPA audio
+plugins capable of (and mainly intended for) realtime operation. The suite
+includes DSP units emulating instrument amplifiers, stomp-box classics,
+versatile 'virtual analogue' oscillators, fractal oscillation, reverb,
+equalization and more.
+
+By default, CAPS will use SSE and/or SSE3 optimizations, if they are
+supported on the build host. If you're building a package to be deployed
+on a different system, you might need to set FORCE_SLACK_CFLAGS=yes in
+the script's environment (this will completely disable SSE/SSE3).
+
+This requires ladspa_sdk.

+# 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 ':'.
