pandoc issue

[esskidri]

Hi all,

I have a question regarding the setup.py code. In particular about the following function:

def read_to_rst(fname):
    try:
        import pypandoc
        rstname = "{}.{}".format(os.path.splitext(fname)[0], 'rst')
        pypandoc.convert(read(fname), 'rst', format='md', outputfile=rstname)
        with open(rstname, 'r') as f:
            rststr = f.read()
        return rststr
        #return read(rstname)
    except ImportError:
        return read(fname)

Instead of catching only the import error, is it not better to use a more generic exception?
There are more many cases in which pypandoc can fail, for example if pandoc is not installed, or in the case pandoc is not reachable from pypandoc, even if pandoc is installed.
