Okay. See the simpleAuto functionality. This is now great for simple
cases. It creates a temp local dir to receive the stuff, then monitors
a set of files for changes, and compiles whenever there's a change.

The other modes are rather specific, but show cases when multiple source files are needed.
Naturally, this ought really just to use make, but I'm not smart enough.
