Nice, thanks for the pointer! But would that work in a binary
distribution (i.e., is "build" present in a binary distribution?)?

Sure. But a whole bunch of interfaces *is* coming from a standard package.
What would be your preference for <interface>.version()?
- Output always a string?
- Output always a version number? (Note that currently
singular.version() yields much more than just a version number)
