+drumkv1 (JACK/LV2 drum machine)
+
+drumkv1 is an old-school all-digital drum-kit sampler synthesizer with
+stereo fx. It runs either as a standalone JACK application or an LV2
+instrument plugin.
+
+Optional dependency: The LV2 instrument plugin requires lv2 to be
+installed (auto-detected at compile time).
+
+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.
