some kind of trace facility ?

[Stef Mientki]

hello,

I want to investigate on a regular base the flow of my Python (most of 
them using wxPython) programs.
So I want to have some log facilty, that logs things like
- every time a function / method is called
- the time spent in that function / method (or even better start / 
finish time)
- in case the function / method has some predefined variables, the 
values of these variables
- the caller

As an extra condition, I'm only interested in my own program modules 
(located in a specific subdirectory).

Is there a module available that can perform such a task ?
Any hints to get started ?

thanks,
Stef Mientki
