This is an example notebook

The main purpose of this notebook is to have something to convert with gitnb. There is nothing interesting to see here. In order to make this point perfectly clear, I will start with some difficult math...

Here is a Raw NB Convert block

gitnb-repo|master $ gitnb --help usage: gitnb [-h] {install,configure,nblist,convert} ... GITNB: TRACKING FOR PYTHON NOTEBOOKS positional arguments: {install,configure,nblist,convert} install installs gitnb into local project (writes to .git/hooks/pre-commit configure creates local configuration file (./gitnb_config.py) nblist list all noteboks (that are not in EXCLUDE_DIRS convert convert .ipynb files to .nbpy.py files optional arguments: -h, --help show this help message and exit
