// Put this file in a directory where @stencil/core exists in node_modules, then run:
// $ echo $HTML | node ssr.js [root] [build-dir] [namespace]
// Full example from my use case:
// $ echo '<sam-text text="Hello, world"></sam-text>' | node ssr.js /var/www/stencil/sams-components/dist ../ sam
// Pipes are used because HTML strings can be really long, and bash has limits on how large argument lists can get (~256k usually).
