Where is args.lcov_file being set?

[codingrhythm]

I cannot find anywhere in the code that sets the args.lcov_file, is it possible to pass lcov_file via arguments? I have already generated a coverage.info file, I want to create a report and send to coveralls.

I did some changes in the coverage.py to accept --lcov_file path/to/coverage.info, and everything works fine for me. Can I create a PR for this? or I am using this in a wrong way? Thanks
