I have a python program that does nothing but filter latex output to remove all the cruft. On my latest paper, raw latex spits out 147 lines of nonsense. After my filter, I see about a dozen lines, including all meaningful errors and warnings and a four-line summary like this:

> Number of underfull warnings : 5 > Number of overfull warnings : 0 > Number of undefined references : 0 > Number of missing citations : 0
