/**
 * Create an example playground with shared example deps and optionally linked local
 * angular packages in the source tree under content/examples/example-playground. This
 * is a wrapper around the equivalent bazel binary but adds the --local option to link
 * local packages.
 *   
 * Usage: node ./tools/examples/create-example-playground-wrapper.mjs <example> [options]
 *
 * Args:
 *  example: name of the example
 * 
 * Flags:
 *  --local: use locally built angular packages
 *  --watch: update playground when source files change
