"""Convert from Markdown to OpenOffice for Linux Magazine.

Requirements:

* Python 3+ (doesn't seem to work on Python 2 because of odfpy)
* Latest IPython and Jupyter

Installation:

    pip install ipymd
    pip install odfpy
    git clone https://gist.github.com/99a2316465c84192b630.git md2glmf
    cd md2glmf

Usage:

    python markdow_to_glmf.py somedocument.md

This generates `somedocument.odt`.

Note: the conversion code lives in the ipymd repo at https://github.com/rossant/ipymd
