+" 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).
