/**
 * This script publishes a new version of react-native to NPM.
 * It is supposed to run in CI environment, not on a developer's machine.
 *
 * To make it easier for developers it uses some logic to identify with which version to publish the package.
 *
 * To cut a branch (and release RC):
 * - Developer: `git checkout -b 0.XY-stable`
 * - Developer: `git tag v0.XY.0-rc` and `git push --tags` to git@github.com:facebook/react-native.git
 * - CI: test and deploy to npm (run this script) with version 0.XY.0-rc with tag "next"
 *
 * To update RC release:
 * - Developer: `git checkout 0.XY-stable`
 * - Developer: cherry-pick whatever changes needed
 * - Developer: `git tag v0.XY.0-rc1` and `git push --tags` to git@github.com:facebook/react-native.git
 * - CI: test and deploy to npm (run this script) with version 0.XY.0-rc1 with tag "next"
 *
 * To publish a release:
 * - Developer: `git checkout 0.XY-stable`
 * - Developer: cherry-pick whatever changes needed
 * - Developer: `git tag latest`
 * - Developer: `git tag v0.XY.0`
 * - Developer: `git push --tags` to git@github.com:facebook/react-native.git
 * - CI: test and deploy to npm (run this script) with version 0.XY.0 with and not tag (latest is implied by npm)
 *
 * To patch old release:
 * - Developer: `git checkout 0.XY-stable`
 * - Developer: cherry-pick whatever changes needed
 * - Developer: `git tag v0.XY.Z`
 * - Developer: `git push` to git@github.com:facebook/react-native.git (or merge as pull request)
 * - CI: test and deploy to npm (run this script) with version 0.XY.Z with no tag, npm will not mark it as latest if
 * there is a version higher than XY
 *
 * Important tags:
 * If tag v0.XY.0-rcZ is present on the commit then publish to npm with version 0.XY.0-rcZ and tag next
 * If tag v0.XY.Z is present on the commit then publish to npm with version 0.XY.Z and no tag (npm will consider it latest)
