+" This is based on Vim Python highlighting
+"
+" - introduced highlighting of doctests
+" - updated keywords, built-ins, and exceptions
+" - corrected regular expressions for
+"
+" * functions
+" * decorators
+" * strings
+" * escapes
+" * numbers
+" * space error
+"
+" - corrected synchronization
+" - more highlighting is ON by default, except
+" - space error highlighting is OFF by default
+"
+" Optional highlighting can be controlled using these variables.
