+" Note: Every rule of indentation in MetaPost is very subjective. We might get
+" creative, but things get murky very soon (there are too many corner cases).
+" So, we provide a means for the user to decide what to do when this script
+" doesn't get it. We use a simple idea: use '%>', '%<' and '%=' to explicitly
+" control indentation. The '<' and '>' symbols may be repeated many times
+" (e.g., '%>>' will cause the next line to be indented twice).
+"
+" By using '%>...', '%<...' and '%=', the indentation the user wants is
+" preserved by commands like gg=G, even if it does not follow the rules of
+" this script.
+"
+" Example:
+"
+"    def foo =
+"        makepen(
+"            subpath(T-n,t) of r  %>
+"                shifted .5down   %>

+"        )

+"    enddef

+" The default indentation of the previous example would be:
