Quotes of the month
"I like Leo more the more I use it...It's an unexpected pleasure to
see my (linearly written) code outlined in Leo. I can't wait to use
Leo to start a new project, going from outline to code...Thanks again
for providing the computing community with such a fine piece of
software." -- Jim Shapiro, Ph.D.

"If you think you have used all possible programmer's editors, but
have not yet tried Leo, you are wrong...I rate Leo as a 'must have'
for Python programmers. The code makes for a good read."
-- John Tobler
