+#-----------
+#This module checks availability of Python modules.
+#
+#This module has the following parameters:
+#   PYTHON_EXECUTABLE - Location of python interpreter.
+#   COMPONENTS        - List of python modules to look for.
+#
+#This module defines the following variables:
+#   PY_XXX       - Cached string variable with the location of the module.
+#   PY_XXX_FOUND - Set if the module is available.
+#
+#   Where XXX is the upper case name of the module.
+#
+#Examples
+#   To look for m2r and report error if not found
+#       find_module(PythonModules COMPONENTS m2r)
+#       if (PY_M2R_FOUND)
+#           do something
+#       endif()
+#
+#   To look for m2r and do not report error if not found
+#       find_module(PythonModules OPTIONAL_COMPONENTS m2r)
+#       if (PY_M2R_FOUND)
+#           do something
+#       endif()
