+# Define a function to create Cython modules.
+#
+# For more information on the Cython project, see http://cython.org/.
+# "Cython is a language that makes writing C extensions for the Python language
+# as easy as Python itself."
+#
+# This file defines a CMake function to build a Cython Python module.
+# To use it, first include this file.
+#
+#   include( UseCython )
+#
+# Then call cython_add_module to create a module.
+#
+#   cython_add_module( <module_name> <src1> <src2> ... <srcN> )
+#
+# To create a standalone executable, the function
+#
+#   cython_add_standalone_executable( <executable_name> [MAIN_MODULE src1] <src1> <src2> ... <srcN> )
+#
+# To avoid dependence on Python, set the PYTHON_LIBRARY cache variable to point
+# to a static library.  If a MAIN_MODULE source is specified, 
+# the "if __name__ == '__main__':" from that module is used as the C main() method
+# for the executable.  If MAIN_MODULE, the source with the same basename as
+# <executable_name> is assumed to be the MAIN_MODULE.
+#
+# Where <module_name> is the name of the resulting Python module and
+# <src1> <src2> ... are source files to be compiled into the module, e.g. *.pyx,
+# *.py, *.c, *.cxx, etc.  A CMake target is created with name <module_name>.  This can
+# be used for target_link_libraries(), etc.
+#
+# The sample paths set with the CMake include_directories() command will be used
+# for include directories to search for *.pxd when running the Cython complire.
+#
+# Cache variables that effect the behavior include:
+#
+#  CYTHON_ANNOTATE
+#  CYTHON_NO_DOCSTRINGS
+#  CYTHON_FLAGS
+#
+# Source file properties that effect the build process are
+#
+#  CYTHON_IS_CXX
+#
+# If this is set of a *.pyx file with CMake set_source_files_properties()
+# command, the file will be compiled as a C++ file.
