# This script creates all the static assets for octetz.com.
# It achieves this in the following steps.
#
# 1. Clone all repositories if not already existent in $OCTETZ_PATH
# 2. Convert markdown to html using pandoc against a custom HTML template
# 3. Move generated HTML to $STATIC_SITE_PATH/posts
# 3. Copy images to $STATIC_SITE_PATH/img
