  Cover is a program for analyzing the coverage profiles generated by
  'go test -coverprofile=cover.out'.
  Cover is also used by 'go test -cover' to rewrite the source code with
  annotations to track which parts of each function are executed.
  It operates on one Go source file at a time, computing approximate
  basic block information by studying the source. It is thus more portable
  than binary-rewriting coverage tools, but also a little less capable.
  For instance, it does not probe inside && and || expressions, and can
  be mildly confused by single statements with multiple function literals.
  For usage information, please see:
  	go help testflag
  	go tool cover -help
  package main
