Setting default option values for Tkinter widgets

[Harlin Seritt]

There are certain options for Tkinter widgets that have default values
that I don't much care for (borderwidth, font come to mind) and
continuously change when I'm building interfaces. With a bit of
tweaking I have been able to give the widgets a look that rivals the
best of them. However, I get tired of doing this when I'm writing code
and would like a way that I could universally change them on my system.
I have tried to find where in the class files (Tkinter.py) that I can
change these and haven't been able to find them. Are there certain
lines in certain files/modules/classes that I can change the values for
these things like font, border, etc.?

Thanks,

Harlin
