I made every script follow a standard form: it starts with the id, followed by the description. The description is contained in [[ ]] delimiters. The description is in the global description variable, not in a LuaDoc comment. Other LuaDoc information such as @args and @usage follows the description in a comment. The first paragraph of each description is a a short summary of what the script does. More detailed information, if any, is given in following paragraphs. I also improved some wording and formatting in a few cases.
