About this resource

Release status
This is a historical source-library download, not a managed hosting template. It has not been compiled, boot-tested, or comprehensively security-audited by Mudhaven. Expect possible portability fixes with current compilers. Review the included README and doc/README.UNIX before building; test under an unprivileged account before public use.

Packaging
No original file contents were changed or removed. Original documentation, licenses, copyright notices, credits, source, and world files are preserved. A MUDHAVEN-PACKAGING.txt note records provenance and cleanup.

Licensing
Distributed under the included CircleMUD and DikuMUD licenses, together with applicable contributor notices. These are not unrestricted-use licenses: the included terms impose noncommercial and attribution conditions. Keep all licenses, credits, and notices intact. Consult the bundled license text for the full terms.

Version note
This upload preserves the named historical version; it is not advertised as the latest release.

Compatibility
