overview = """
The Editor class implements a simple text editor using wxPython.  You
can create a custom editor by subclassing Editor.  Even though much of
the editor is implemented in Python, it runs surprisingly smoothly on
normal hardware with small files.

How to use it
-------------
The demo code (demo/Editor.py) shows how to use Editor as a simple text
box. Use the SetText() and GetText() methods to set or get text from
the component; these both use a list of strings.

The samples/FrogEdit directory has an example of a simple text editor
application that uses the Editor component.

Subclassing
-----------
To add or change functionality, you can subclass this
component. One example of this might be to change the key
Alt key commands. In that case you would (for example) override the
SetAltFuncs() method.
