to make a section foldable, surround it in { curly braces }
these curly braces must also be inside a comment, or the file will fail to parse in-game
eg.
# { Section 1
...
...
# } end Section 1
You may also open and close a section on the same line, but you must put at least a space between the braces
# { Section 1
...
# } { Section 2
...
# }
