+
+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: 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
+
+For reasons of disambiguation it is installed as 6cov although it also serves
+as an 8cov and a 5cov.
