/**
* We may want to store the prebuild in the same directory as the page
* file instead of the current working directory. There will often be
* an npm script that is running at the base of the project. In the
* AWS Lambda case, we want the prebuild file to live alongside of the
* page itself. We need to preprocess all of the builds and then write
* them individually after because there may be multiple pages that live
* in the same directory as well as multiple builds for the same page
* with different flags.
