+BINDINGS
+--------
+
+High-level, object-oriented bindings for C++ and python3 are provided. They
+can be enabled by passing --enable-bindings-cxx and --enable-bindings-python
+arguments respectively to configure.
+
+C++ bindings require C++11 support and autoconf-archive collection if building
+from git.
+
+Python bindings require python3 support and libpython development files. Care
+must be taken when cross-compiling python bindings: users usually must specify
+the PYTHON_CPPFLAGS and PYTHON_LIBS variables in order to point the build
+system to the correct locations. During native builds, the configure script
+can auto-detect the location of the development files.
+
+Both bindings are extensively documented: with doxygen markup in case of C++
+and inline pydoc comments for python.
