    This script runs 'npm publish', but also ensures $PACKAGE_JSON and $BOWER_JSON contain matching version numbers if
    applicable. If the versions do not match, the script exists with an error.

    The -d switch publishes the $DIST_DIR directory by copying its contents to the root directory. The .npmignore file
    is expected to list anything in the root that should not be published.

    The -e switch is an experimental implementation that publishes within the $DIST_DIR directory.
