Build 4X60 adds 19 new examples and modernises a dozen others, and presents
a new volume of built-in documentation: the Inform Recipe Book. It also
provides new features for variable text, improves and extends table-handling,
allows Glulx-format games to read and write files and communicate with
external programs, and allows extensions to create more readable and
useful documentation.

**This is no longer the current build**. Almost all users should look for the
latest one. **Old builds like this are unsupported**, and are kept only for the
benefit of people who need exactly to recreate the system as it stood in
the past, perhaps to replicate an old Inform project.
