Question (Development) What are these apparently-undefined python operators?

I'm looking at the calibre/gui2/convert/look_and_feel.py module, and it's got a bunch of operators in it whose provenance I can't determine:

Code:
    TITLE = _('Look & Feel')
    ICON  = I('lookfeel.svg')
    HELP  = _('Control the look and feel of the output')
The "_" and "I" functions... what are those and where are they defined?

They are special builtins the calibre environment defines. They are for easy access to resource files (icons/templates/etc.) and are defined in calibre.utils.resources

Well, that explains it. I'm editing using Emacs with flymake (an on-the-fly syntax checker) and it's choking on all of these undefined functions. I guess I need to figure out how to make it aware of those functions.

@kovidgoyal: If you're still tracking this, I'm interested in maybe doing some ui tweaking in the preferences dialog, on Mac OSX. Does the QT designer work with these ui definitions, or do I have to modify them by hand?

There's usually a way to specify builtins for syntax checkers.I use vim with pyflakes and that allows you to set a global variable with a list of extra builtins.
