${pkg.name} v${pkg.version} - ${pkg.description}

Executes all the files and interprets their output as TAP
formatted test result data.  If no files are specified, then
tap will search for testy-looking files, and run those.
(See '--test-regex' below.)

To parse TAP data from stdin, specify "-" as a filename.

Short options are parsed gnu-style, so for example '-bCRspec' would be
equivalent to '--bail --no-color --reporter=spec'

If the --check-coverage or --coverage-report options are provided
explicitly, and no test files are specified, then a coverage report or
coverage check will be run on the data from the last test run.

Coverage is never enabled for stdin.

                  on their stdin.
