Commands for the menu only
- The menu-specific commands have to be used before any others.
- The files must be in plain-text format.
- # at the beginning of a line in a configuration file means it is only a comment.
- Options are separated by spaces.
- All numbers can be either decimal or hexadecimal. A hexadecimal number must be preceded by `0x', and is case-insensitive.
- Extra options or text at the end of the line are ignored unless otherwise specified.
- Unrecognized commands are added to the current entry, except before entries start, where they are ignored.
