* .ci/install-deps.sh: Adding install of gcc versions on macOS depending on CC variable.

* .travis.yml: Removing installation of gcc from matrix setup (the local c++ executable has to be removed first).

* .ci/install-deps.sh: Install the right gcc formula using brew.

* .travis.yml: Also set CXX to gcc6, if CC is set to it.

* .travis.yml: Removing disabling of options (they will be disabled automatically, if not available).

* .travis.yml: Looking at what we're deleting in /usr/local/include/c++.

* .travis.yml: Uninstalling oclint, if it's installed, as it conflicts with gcc.

* .travis.yml: Test what removal of include-fixed stdio.h will do (otherwise there's a broken include of a _stdio.h).

* .travis.yml: Creating one-liner for header removal, adding ; to configure.

* .travis.yml: Fixing indent. Adding ; for one-liner.

* .travis.yml: Moving to xcode9.2 image for testing, as the stdio.h issue seems xcode related (probably a bug with 9.4). Removing header removal.

* .travis.yml: Adding -flax-vector-conversions to CXXFLAGS to fix vector conversion problems.

* .travis.yml: Trying xcode8.3 with the build in the hopes that CoreAudio will behave more nicely.

* .travis.yml: Moving to clang for all OSX based builds for now, as brew installed gcc proves to be very complicated.

* .travis.yml: Removing support for Xcode 7.3. That stuff is too old.

+`JACK2 <http://jackaudio.org/>`_
+################################
+
+.. image:: https://travis-ci.org/jackaudio/jack2.svg?branch=master
+   :target: https://travis-ci.org/jackaudio/jack2
+
+JACK2 aka jackdmp is a C++ version of the JACK low-latency audio server for
+multi-processor machines. It is a new implementation of the JACK server core
+features that aims in removing some limitations of the JACK1 design. The
+activation system has been changed for a data flow model and lock-free
+programming techniques for graph access have been used to have a more dynamic
+and robust system.
+
+- uses a new client activation model, that allows simultaneous client
+  execution (on a SMP machine) when parallel clients exist in the graph (client
+  that have the same inputs). This activation model allows to better use
+  available CPU on a smp machine, but also works on mono-processor machine.
+
+- uses a lock-free way to access (read/write) the client graph, thus
+  allowing connections/disconnection to be done without interrupting the audio
+  stream. The result is that connections/disconnections are glitch-free.
+
+- can work in two different modes at the server level:
+
+  - *synchronous activation*: in a given cycle, the server waits for all
+    clients to be finished (similar to normal jackd)
+
+  - *asynchronous activation*: in a given cycle, the server does not wait for
+    all clients to be finished and use output buffer computed the previous
+    cycle.
+    The audible result of this mode is that if a client is not activated
+    during one cycle, other clients may still run and the resulting audio
+    stream will still be produced (even if its partial in some way). This
+    mode usually result in fewer (less audible) audio glitches in a loaded
+    system.
