Title: Unit Test Tools
Author: Graham Nelson

@ Some of the modules making up the Inform compiler are buried deeply enough
that it's useful to be able to test them externally, i.e., other than by
trying to compile an Inform source text.

To do this we use small stand-alone tools which put a rudimentary command-line
interface around the module in question. These are those tools. This testing
code is not included anywhere else, and in particular it's not a part of the
Inform compiler.
