+   * Background:
+   * We introduced a release branch as a staging area for the next release
+   * while development continues in the master branch. Eventually we publish the packages from
+   * the release branch and make the version bumps in package.json and tags. It creats a merge
+   * commit in the master branch when we merge the release branch back.

+   * Only skip a package if you are sure Lerna listed the package in mistake.
+   * If you skipped a package, it won't show up in the candidate list going forward
+   * unless additional changes are made in this package.
