Build is still looking for conf.py in source directory despite using -c option

[maryaB-osr]

Hi, I'm getting the following error when trying to run sphinx-multiversion -c . source build/html (where source is <source-dir> according to sphinx-build docs, but conf.py is in the directory one level up):

Configuration error:
There is a programmable error in your configuration file:

Traceback (most recent call last):
  File "/home/marya/py3venv/lib/python3.6/site-packages/sphinx/config.py", line 319, in eval_config_file
    execfile_(filename, namespace)
  File "/home/marya/py3venv/lib/python3.6/site-packages/sphinx/util/pycompat.py", line 63, in execfile_
    with open(filepath, 'rb') as f:
FileNotFoundError: [Errno 2] No such file or directory: '/tmp/tmp7lb2mv5u/7687b9e76fa53a6f2197c5ab84ab1325b546d19b/source/conf.py'

It looks like the tool is still looking for conf.py in source even though I'm using -c. The same statement works when using sphinx-build instead of sphinx-multiversion so I think it might be a bug with how sphinx-multiversion handles -c.

Directory structure:

+-- .

|    +-- build
|    +-- source
     |   +-- index.rst
|    +-- conf.py

Hi @maryaB-osr, thanks for reporting this issue.

I pushed a fix in PR #13. Please check if it works for you.

Hi @Holzhaus, sorry for the delay. I was able to get the versions built with #13.
There is another issue (not being able to get the versions/branches/tags list to render in the side bar) that I was trying to debug, but it seems to most likely be a separate issue. So you can merge/close, thanks!
