# 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.
#
# qsgen2 uses different templates and its own formattings tags to generate the static HTML pages.
#
# The file structure in the project directory should look like this:
#
# .blog_cache
# .pages_cache
# config
# index.tpl
# templates/
# templates/<theme>/pages.tpl
# templates/<theme>/blogs.tpl
# templates/<theme>/blog_index.tpl
# blog/
# blog/2024-01-26-1.blog
#
# Explanation of the file structure.
# The file 'config' contains the settings for this specific project.
# The file 'index.tpl' is what becomes index.html that is served to the public.
# The 'templates/' directory contains the templates used to generate the pages and blog posts.
# The 'blog/' directory contains the blog posts. The date format of the files are used to create a blog/index.html with the newest post first.
#
# Contents of the file 'config' --> CHANGE THESE <--
# export site_name="The name of the website"

# export project_dir=${HOME}/www/vikingo
