8# Generate test coverage statistics for Go packages.
9#
10# Works around the fact that `go test -coverprofile` currently does not work
11# with multiple packages, see https://code.google.com/p/go/issues/detail?id=6909
12#
13# Usage: script/coverage [--html|--coveralls]
14#
15# --html Additionally create HTML report and open it in browser
16# --coveralls Push coverage statistics to coveralls.io
17#
18# Changes: directories ending in .go used to fail
