    Distutils command to build Sphinx documentation.

    The Sphinx build can then be triggered from distutils, and some Sphinx
    options can be set in ``setup.py`` or ``setup.cfg`` instead of Sphinx own
    configuration file.

    For instance, from `setup.py`::

       # this is only necessary when not using setuptools/distribute
       from sphinx.setup_command import BuildDoc
       cmdclass = {'build_sphinx': BuildDoc}

       name = 'My project'
       version = '1.2'
       release = '1.2.0'
       setup(
           name=name,
           author='Bernard Montgomery',
           version=release,
           cmdclass=cmdclass,
           # these are optional and override conf.py settings
           command_options={
               'build_sphinx': {
                   'project': ('setup.py', name),
                   'version': ('setup.py', version),
                   'release': ('setup.py', release)}},
       )

    Or add this section in ``setup.cfg``::

       [build_sphinx]
       project = 'My project'
       version = 1.2
       release = 1.2.0

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
