Yes. I want to be able to type “showimage …” at the lldb prompt and
have that run some Python code that does the image showing.

Ah, I see: so I would write a Python function and then set up an alias
so that “showimage” would call it? How do I ensure that my Python
function is available to the Python interpreter within lldb? Should I
put it in a particular directory?

I also need to know how my Python script can get access to the debugger.
Is there some global variable that is an SBDebugger object for the
debugger that is running, which my script can use?
