Tested:

• Ultima-V-1.1.70-linux-x86_64.AppImage from release v1.1.70

Compatibility: not self-contained: uses the C library of the system; uses an old AppImage runtime that needs the C library (and libfuse2) of the system; references glibc 2.25

Names:

WARNING: AppImage name 'Ultima-V-1.1.70-linux-x86_64.AppImage': should not contain 'Linux', since all AppImages are for Linux (e.g. 'App-1.0-x86_64.AppImage', not 'App-1.0-linux-x86_64.AppImage')
WARNING: File name 'ultima5': does not match the name of the application in its desktop file ('Ultima V'); the file should be named after the application

Notes:

• File name 'ultima5': all-lowercase names are typically used for command line tools, but the desktop file does not set Terminal=true. If this is a graphical application, please name the file after the application as it is spelled, with capitals where it has them (e.g. 'Krita'); if it is a command line tool, set Terminal=true in its desktop file.

Warnings:

• Please check the remarks about the names below.
• The AppImage contains no update information, so users cannot update it with AppImageUpdate or similar tools. Please consider embedding it when building the AppImage (e.g., appimagetool -u) and publishing the .zsync file next to the AppImage; see https://docs.appimage.org/packaging-guide/optional/updates.html
