This is a little dinky node server wrapper over a bunch of bash scripts that are responsible for compiling Goonstation, as well as the ancillary services such as CDN files.
What you see here is a collection of legacy code grandfathered in from over the past decade, as well as smattering written hurriedly over a weekend. As such, quality is dubious, and comments are sparse. This tool is provided as-is and you, the reader, and not expected to be able to run this in any capacity without the underlying server architecture and supporting services.
