checklist:

• [] Emphasis on readability and understandability.
• [] Limit lines to 80 characters long.
• [] Proper indenting. Exactly 4 spaces, no tabs.
• [] No double-slash comments. /* only */
• [] Zero special characters, no unicode. Beware of PDF copy/paste.
• [] See template for example CoolThing() function.
• [] All functions should return a value. No void function returns.
• [] Functions with no arguments must have (void) in arg list.
