bundled/cherrypy/cherrypy/tutorial/tut08_generators_and_yield.py @ 22de90ef33ed 

Add identifiers to ReviewChangeset's and ReviewSignoff's.

The identifier of a rcset/rsignoff is the filename it was saved as, which is
the hash of its contents.

This will be useful when we want to add replies to comments/signoffs.

CLI support for this feature has also been added (using --verbose and --debug
flags with 'hg review [-r REV]'), as well as some simple unit tests.

Bonus Tutorial: Using generators to return result bodies

Instead of returning a complete result string, you can use the yield
statement to return one result part after another. This may be convenient
in situations where using a template package like CherryPy or Cheetah
would be overkill, and messy string concatenation too uncool. ;-)
