console.log takes multiple arguments. We only want to print the first one, the actually message.
There’s a common tool included in Hadoop that also has a `yarn` command,
which created issues for users who had Hadoop installed:
* #1257
* #1363
Yarn also installs the command under `yarnpkg` alias (added in
cefa9a368d)
so we can use `yarnpkg` instead of `yarn` to make it more reliable.
This has no effect on users who don't have Hadoop installed, but those
who have won't see errors from falsely detecting Hadoop Yarn as Yarn
the package manager, and they can now also install Yarn to make use of
our Yarn support without the Hadoop Yarn interfering.

Use a 'BROWSER' environment variable with npm start to specify which
browser to open. if the value of 'BROWSER' is not valid executable file,
don't open any browser.
* Use "commander" for cli argv handling
* Handle different scripts version forms and exits without a name given
* Revert comment about min supported node version
* Check sooner for the minimal node version
* Add travis test for node <4
* Parse stderr in node versions <4
* Remove the “‘yarn’ is not recognized as an internal or external
command, ...” message on Windows
* Simplify the detection code: just run `yarn --version` – if it
succeeds use `yarn`, if it fails use `npm`.
- Use “Chrome” instead of "Google Chrome", It will try to use current active browser.
otherwise, use default.
- If “Chrome”s aren’t running, will fallback to opn(url)
* Let Jest handle all file types
* Update regexes
* Fix exclusion regex to also exclude files without extension
* Be over-cautious with Windows paths because I'm not sure how Jest handles them
* There is no automatic babel-jest discovery now that we use transsform
