+jamulus (real-time jam session client/server)
+
+The Jamulus software enables musicians to perform real-time jam sessions
+over the internet. There is one server running the Jamulus server software
+which collects the audio data from each Jamulus client, mixes the audio
+data and sends the mix back to each client.
+
+The jamulus binary can be run as a client (default) or a server. See
+"jamulus --help" and SERVER.txt for details.
+
+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.

+By default, the jamulus binary can function as:
+
+- Client with GUI (default mode, X and jackd must be running)
+- Server with GUI (-s option, only X must be running)
+- Headless server (-s and -n options, neither X nor jackd required)
+
+Even though the headless mode doesn't require a running X server,
+it still requires the qt4 and X11 shared libraries. There's no way to
+compile jamulus without these.
+
+If you launch jamulus from the desktop start menu, you'll get the client.
+If you want to run a server, you'll have to either run it from the command
+line, or create a different launcher/shortcut for jamulus as a server.
+
+If you want to run a headless server that starts at boot time (like
+a regular daemon), currently the best way to do this is to call it
+from /etc/rc.d/rc.local. There's no "daemon" option, so you'll have to
+background it with &, and redirect stdout/stderr somewhere (see also
+the -l <logfile> option).
+
+If you *really* want to build a dedicated jamulus server, you can do
+so by setting SERVERONLY=yes in the SlackBuild's environment. In this
+case, you can ignore the REQUIRES="jack-audio-connection-kit" line in
+the .info file.
+
+The resulting jamulus binary will work exactly as the regular jamulus,
+except it doesn't make sound nor accept audio input from your instrument.
+It'll only be useful as a server (with -s and possibly also -n).
+
+The *only* reason to ever do this is if you really *really* don't want
+to install jack-audio-connection-kit for some reason.
+
+For those who want to complain that I shouldn't have listed
+jack-audio-connection-kit as required: It *is* required, for the *normal*
+use case. Building without JACK support is a very specialized thing,
+not useful to the general population of users.

+# 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.
