Given a set of entries from Day One on mac, that is uploaded as a zip file to ~/dayone/ and an empty dir ~/markdown:

$ node processDayone.js --inputZip ~/dayone/<zip> --root ~/markdown

This will:-
1. Run day-one-to-markdown script to get a set of directories each containing one front matter format markdown file
2. Load the frontmatter markdowns, and create gemtext and html
3. Process the images to be ready for distribution (strip EXIF, ensure rotation, smallify)

Note also:
* The DEPENDENCIES file discusses what's needed in the environment that the script is run
* The TODO file is my super-advanced issue tracking system
* There's no license yet
