description="""
Generate documentation from source files.
sphinx-build generates documentation from the files in SOURCEDIR and places it
in OUTPUTDIR. It looks for 'conf.py' in SOURCEDIR for the configuration
settings. The 'sphinx-quickstart' tool may be used to generate template files,
including 'conf.py'
sphinx-build can create documentation in different formats. A format is
selected by specifying the builder name on the command line; it defaults to
HTML. Builders can also perform other tasks related to documentation
processing.
By default, everything that is outdated is built. Output only for selected
files can be built by specifying individual filenames.
