Opens xkcd's downloaded using xkcd-dl chronologically, waiting for user input between each comic

xkcd-read.py

#!/usr/bin/env python3

"""
Opens xkcd's downloaded using xkcd-dl chronologically using the show_xkcd function from
https://github.com/tasdikrahman/xkcd-dl/
Assumes you already have the xkcd's downloaded in the xkcd_archive folder (i.e. using --download-all)
(though you could just have the start/end folders in xkcd_archive and xkcd-dl would download them when asked to open)

Can pass a start xkcd like:

xkcd-read 5

If on mac, install using 'pip3 install git+https://github.com/tasdikrahman/xkcd-dl' as the version on pypi doesnt
current detect if you're on mac and assumes xdg-open
