Parchment and the Z-machine interpreter
---------------------------------------

Base release: Parchment 2025.1.14
Source: https://github.com/curiousdannii/parchment
Revision: 01948aa83feec25e6cc7d41e023ffe61983acfe6
Release page: https://github.com/curiousdannii/parchment/releases/tag/2025.1.14
Bundled files: interpreter/parchment.js, interpreter/parchment.css
License: MIT License; see licenses/PARCHMENT-MIT.txt

This is a custom, Z-code-only build. It replaces Parchment's GPL-licensed
Bocfel backend with the MIT-licensed ifvms.js ZVM, and uses the matching
MIT-licensed Glk API and local-storage dialog so explicit saves, restores,
and autosaves continue to work. The dialog also has local accessibility
labels. Build provenance and the source changes are recorded in SOURCE.txt
and INTERPRETER-PATCH.diff.
