If you are making a GitHub pull request for NetHack, please follow these guidelines: 1. The 50/72 Rule: Keep the subject line (the first line) under 50 characters for readability in git log --oneline. If you need a more detailed description (the body), wrap it at 72 characters. 2. Separate Subject from Body: Always include a blank line between the subject and the body. This helps Git tools correctly parse the message. # NetHack 5.0 Contributing.txt $NHDT-Date: 1778531111 2026/05/11 20:25:11 $ $NHDT-Branch: NetHack-5.0 $:$NHDT-Revision: 1.3 $ # NetHack may be freely redistributed.
