  + * This file re-exports all symbols contained in this directory.
  + *
  + * Why is this file not `index.ts`?
  + *
  + * There seems to be an inconsistent path resolution of an `index.ts` file
  + * when only the parent directory is referenced. This could be due to the
  + * node module resolution configuration differing from rollup and/or typescript.
  + *
  + * With commit
  + * https://github.com/angular/angular/commit/d5e3f2c64bd13ce83e7c70788b7fc514ca4a9918
  + * the `instructions.ts` file was moved to `instructions/instructions.ts` and an
  + * `index.ts` file was used to re-export everything. Having had file names that were
  + * importing from `instructions' directly (not the from the sub file or the `index.ts`
  + * file) caused strange CI issues. `index.ts` had to be renamed to `all.ts` for this
  + * to work.
  + *
  + * Jira Issue = FW-1184
