[ via Brown Hen ] Leo is an outliner/literate-programming editor written in Python and TclTk. To run it under Mac OS X you need to install TclTk and a version of Python that can talk to TclTk.
When you’re installing the Leo scripts, I found that you shouldn’t rename $LEO_HOME/leo.py to $LEO_HOME/leo.pyw, as the instructions say, because it will break the imports. The wrapper script for wpython will take care of executing leo.py with the right Python interpreter.
