In case you’re turning here to see why the Language Construction Kit is not available this week— it’s because I’ve uploaded a corrected edition. It should be available again in about a week.
The edition should get rid of those embarrassing typos, improves the typography (we got in a new shipment of hyphens), and improves a few sentences. Here’s a summary of the most important changes and additions. (I don’t list the corrected typos, except for one where the intended meaning was unclear.)
