# Quick Site Generator 2 is a static website generator inspired by Nikola.
# It is written for the Z shell (zsh) because that's what I use and also because I like it better than Bash.
#
# This script is an almost complete rewrite of my old script because it became overly complicated and
# had way too many bugs, even though it worked on simple sites.
