+C++ Installation Instructions
+=============================
+
+0.  Get the source and deal with submodules:
+    + git clone [email protected]:davidbaraff/OpenTimelineIO.git otio
+    + cd otio
+    + git checkout cxx1
+    + git submodule init
+    + git submodule update
+
+1. If you want to only build for C++ development (i.e. produce the OTIO C++ libraries and header files), then use cmake:
+    + mkdir build
+    + cd build
+    + ccmake ..
+    (configure PYTHON_EXECUTABLE, PYTHON_LIBRARY, and CMAKE_INSTALL_PREFIX)
+    + make install
+
+2. If you wish to build only for use with Python, run one of the following two commands:
+   + pip install .
+   + python setup.py install
+
+3. However, if you want to build for Python but you also want to install the OTIO C++ headers and libraries, then run one of the following two commands
+   + pip install . --install-option=“--cxx-install-root=/home/someone/cxx-otio-root"
+   + python setup.py install --cxx-install-root=/home/someone/cxx-otio-root
+
+   To compile a C++ file, add the following -I flags:
+   + c++ -c source.cpp -I/home/someone/cxx-otio-root/include -I/home/someone/cxx-otio-root/include/opentimelineio/deps
+
+   To link, add the following -L/-l flags:
+   + c++ ... -L/home/someone/cxx-otio-root/lib -lopentimelineio
+
+   (If you are using only opentime, not opentimelineio, use -lopentime.  Also, you could leave out the second -I flag.)
