Leo is:

• An outliner. Everything in Leo is an outline.
• A Personal Information Manager.
• A browser with a memory.
• A powerful scripting environment.
• A tool for studying other people's code.
• A fully-featured IDE, with emacs-like commands.
• Extensible via a simple plugin architecture.
• A tool that plays well with IPython, vim and xemacs.
• Written in 100% pure Python
• Compatible with Python 2.6 and above or Python 3.0 and above.

Leo's unique features:

• Always-present, persistent, outline structure.
• Leo's underlying data is a Directed Acyclic Graph.
• Clones create multiple views of an outline.
• A simple, powerful, outline-oriented Python API.
• Scripts and programs can be composed from outlines.
• Importers convert flat text into outlines.
• Scripts have full access to all of Leo's sources.
• Commands that act on outline structure.
  Example: the rst3 command converts outlines to reStructuredText.
• @test and @suite scripts create unit tests automatically.
• @button scripts apply scripts to outline data.
• Outline-oriented directives.

Simulating these features in vim or Emacs is possible, just as
it is possible to simulate Python in assembly language...
