-All text before the header will be treated as comment, as long as you avoid using the word "red" 
-starting with a capital "R" in this pre-header text. This is a temporary shortcoming of the used lexer but

 The header of a red script is the capitalized word "red" followed by a 
 whitespace character followed by a block of square brackets [].
-The block of brackets can be filled with useful information about the script or program: the author, 
-the filename, the version, the license, what the program does or needs.
-The red/System header is just like the red header, only saying "red/System" and not "red".
