# ---------------------

# - template_path: Add any paths that contain templates here, relative to this directory.
# - master_doc: The master toctree document.
# - project
# - copyright
# - github_project_url
# - source_suffix = config["sphinx"]["source_suffix"]
# - exclude_patterns:
#       Exclude these glob-style patterns when looking for source files.
#       They are relative to the source/ directory.
# - pygments_style: The name of the Pygments (syntax highlighting) style to use.
# - default_role
# - modindex_common_prefix


# Options for HTML output
# -----------------------
# - html_theme
# - html_static_path
#     Add any paths that contain custom static files (such as style sheets) here,
#     relative to this directory. They are copied after the builtin static files,
#     so a file named "default.css" will overwrite the builtin "default.css".
#     Favicon needs the directory name
# - html_favicon
# - html_last_updated_fmt = config["html"]["html_last_updated_fmt"]
#     If not '', a 'Last updated on:' timestamp is inserted at every page bottom,
#     using the given strftime format.
#     Output file base name for HTML help builder.
# - htmlhelp_basename

# Additional templates that should be rendered to pages, maps page names to
# template names.

# Options for LaTeX output
# ------------------------

# Grouping the document tree into LaTeX files. List of tuples
# (source start file, target name, title, author, document class [howto/manual]).
