  == Sphinx documentation
  
  Erlang.mk includes targets for running
  http://www.sphinx-doc.org/[Sphinx documentation generator], which can produce
  documentation in various formats, like HTML, man pages, Texinfo, LaTeX, and
  others.
  
  === Writing Sphinx documentation
  
  Sphinx generates documentation form a set of
  http://www.sphinx-doc.org/en/stable/rest.html[reST] documents. There is
  a http://www.sphinx-doc.org/en/stable/tutorial.html[quick start guide] on
  Sphinx' website. For Erlang.mk, we'll set up a minimal environment instead.
  
  === Basic setup
  
  By default, Erlang.mk expects Sphinx documentation to be placed in 'doc'
  directory, with 'doc/conf.py' config file in particular. The file contains
  information about the project, among the other things.
