 ### License header semantics
 
 The license header is always at the beginning of the file and ends after two newlines. If there isn't one, or it doesn't contain the required copyright contents, wpiformat inserts a new one containing the current year.

 `{year}` is replaced with a year range from the earliest copyright year in the file to the current year. If the earliest year is the current year, only that year will be written.
