Add a script to compare directories full of gcov output We can't just use "diff", since we don't care about changes in line numbers, or changes in the exact number of times a line was called. We just care about changes that make lines covered or non-coverd. So pre-process the files before calling diff. 2013-07-09 12:54:39 -04:00			`#!/bin/sh`

Adopt the LCOV convention for marking lines as unreachable by tests. Document this convention. Add a script to post-process .gcov files in order to stop nagging us about excluded lines. Teach cov-diff to handle these post-processed files.
