'''
If MyShell is passed a boolean true filter value, it will attempt to parse
lines recieved as if it were recieving Python. This allows you to add and
change code you want sent to the interpreter until you get it right. When a
complete "command" is ready to be sent to the underlying shell, PyPE will
attempt to interact with the underlying Python shell as you would. Sometimes
this doesn't work quite as well as one would hope, and there are extra '...'
and '>>>' which make it to the Python shell. This shouldn't affect the actual
execution of the code you send to the Python shell, just what you see.
If you don't like this buffering, etc., you can run the command shell (pass a
boolean false filter value), which only buffers a single line at a time.
Whenever the user hits "enter", the current command line is immediately sent
to the underlying shell. This allows you to use a standard Python shell,
without buffering (you get the actual command-line interaction) via:
python -u -i -c ""
Note that for some reason, the 'python -u' doesn't work. Your guess is as
good as mine as to why this is.
