/usr/bin/emacs-31.1

Usage: /usr/bin/emacs-31.1 [OPTION-OR-FILENAME]...

Run Emacs, the extensible, customizable, self-documenting real-time
display editor.  The recommended way to start Emacs for normal editing
is with no options at all.

Run M-x info RET m emacs RET m emacs invocation RET inside Emacs to
read the main documentation for these command-line arguments.

You can generally also specify long option names with a single -; for

abbreviation for a --option.

Various environment variables and window system resources also affect
the operation of Emacs.  See the main documentation.
