-Building Documentation
-======================
-
-The documentation for cliff is written in reStructuredText and
-converted to HTML using Sphinx. The build itself is driven by make.
-You will need the following packages in order to build the docs:
-
-- Sphinx
-- docutils
-
-Once all of the tools are installed into a virtualenv using
-pip, run ``make docs`` to generate the HTML version of the
-documentation::
-
-    $ make docs
-    (cd docs && make clean html)
-    sphinx-build -b html -d build/doctrees   source build/html
-    Running Sphinx v1.1.3
-    loading pickled environment... done
-    building [html]: targets for 1 source files that are out of date
-    updating environment: 1 added, 1 changed, 0 removed
-    reading sources... [100%] index                                                 
-    looking for now-outdated files... none found
-    pickling environment... done

-    copying static files... done
-    dumping search index... done
-    dumping object inventory... done
-    build succeeded, 2 warnings.
-
-    Build finished. The HTML pages are in build/html.
-    
-The output version of the documentation ends up in
-``./docs/build/html`` inside your sandbox.
