# CLI for First Data conversion rates

## Requirements
* python3 with modules `PyPDF3`, `appdirs`, `mechanize`

### Caveat:
Currently [python-mechanize](https://github.com/python-mechanize/mechanize) is not available via pip3.
Therefore, you need to clone mechanize and symlink its mechanize/ directory here.
