Overview

Cov is a rudimentary code coverage tool.

Given a command to run, it runs the command while tracking which sections of code have been executed. When the command finishes, cov prints the line numbers of sections of code in the binary that were not executed. With no arguments it assumes the command "6.out".

Usage: go tool cov [-lsv] [-g substring] [-m minlines] [6.out args]

The options are:

-l
	print full path names instead of paths relative to the current directory
-s
	show the source code that didn't execute, in addition to the line numbers.
-v
	print debugging information during the run.
-g substring
	restrict the coverage analysis to functions or files whose names contain substring
-m minlines
	only report uncovered sections of code larger than minlines lines

The program is the same for all architectures: 386, amd64, and arm.
