usage: sphinx-build [OPTIONS] SOURCEDIR OUTPUTDIR [FILENAMES...]

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 By default, everything that is outdated is built.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.
