What: Leo
 Where: http://leo.sourceforge.net/
 Description: Leo is a programmer's editor and a flexible browser for projects,
       programs, classes or data. Leo clarifies design, coding, debugging, 
       testing and maintenance. Leo is an outlining editor. Outlines clarify 
       the big picture while providing unlimited space for details. Leo is a 
       literate programming tool, compatible with noweb and CWEB. Leo enhances 
       any text-based programming language, from assembly language and C to Java, 
       Python and XML. There is a Tcl/tk mode so Leo is aware of Tcl commands. 
       What I particularly like is the ability to have all my code and 
       documentation together in one place and publish the code when I save the file. 
       When I change the code in another editor, then open it in Leo, the Leo file is 
       updated automatically.
       Runs wherever Python runs. [Has anyone else noticed that Python seems to 
       stimulate programming creativity and a number of innovative systems have been 
       released in this language recently. This is not saying that I am not impressed by 
       some of the Tcl/tk programs I have come across here: I am!]
