# Static maker:
# This catastrophic Script cleans the MainFunctions js from earlier executions and then loads all with comments marked HTML files and turns them into static HTML strings so they can be loaded NON-ASYNC. Why? Loading HTML-Code ASYNC works BUT it causes issues with classes and CSS and with Archives and all types of web-tools like translators. I want a way to easily and CLEANLY develop for my website WITHOUT turning HTML code into strings for JavaScript to directly use. I could load them with mainThread load methods BUT this is deprecated and works BAD! So I use this script. It automates it and AS LONG as I keep to my own define limitation so the script can execute cleanly this should work fine.

# IMPORTANT: The loaded HTML MUST have a EMPTY LINE at the end!!!
