David Goodger writes:

* Refactored the file I/O model throughout, to support multiple
  processing paths.  PEP source text is now read into a list of lines.

* In ``fixfile()``:

  - Updated its parameters for the new I/O model.
  - Changed ``fo`` to ``outfile``, ``fi`` to ``inpath`` and
    ``input_lines``.
  - Input is read in by iterating over the list of input lines, rather
    than using "readlines()".
  - Opening and closing of files is done by the caller, "make_html()".
  - Added PEP number processing in Requires header.
  - Linked "Content-Type: text/plain" to PEP 9.

* Added ``fix_rst_pep()``, which imports and calls Docutils code.

* Added ``get_pep_type()``, which checks for a Content-Type header and
  returns the value, defaulting to "text/plain".  If no PEP header is
  found, ``None`` is returned: input is not a PEP.

* Added ``get_input_lines()`` to read input file into a list.

* Expanded ``make_html()`` to catch errors and process the different
  PEP formats via the new ``PEP_TYPE_DISPATCH`` dict.

* Added ``check_requirements()`` to check both Python and Docutils
  requirements.  ``pep_type_error()`` is called if the required
  software is not available.

* In ``main()``:

  - Added an ``argv`` parameter, so that pep2html.py can be imported
    and command-line options passed in.  Yes, I use this functionality
    in the Docutils "buildhtml.py" front end.
  - Files skipped (due to an error) are not pushed onto the server.
