-Tool-specific initialization for the Sphinx document build system.

-It will usually be imported through the generic SCons.Tool.Tool()
-selection method.
-
-It should be placed in e.g. ~/site_scons/site_tools/sphinx4scons/
-directory. Then it may be loaded by placing
-
-  sphinx = Tool('sphinx4scons')
-  sphinx(env)

-in your SConstruct file.
-
-For further details, please see the SCons documentation on how to
-install and enable custom tools.
