Minor post-script: if all you need is warp + wai-app-static without
any custom code, then you can just use the warp-static[1] package. I
mostly just use this when testing HTML bundles on my work system and
need to serve from a web server to bypass Javascript-from-file://
issues. In production, if you really just need static file serving, I
would also tend to recommend nginx instead.
