with a PGP key and add your name and the year to the bottom of the list of
copyright holders for the file. For example, an existing copyright header might
read:

You would add your name below it like this:

 * Copyright (c) 2022–2023 Emma Tebibyte <emma@tebibyte.media>

We accept contributions from people using aliases.

Only list years in which you modified the source file. For example:

 * Copyright (c) 2020–2021, 2023 Your Name <your-address@example.com>

This header shows that “Your Name” worked on this source file in 2020, 2021, and

notice.

If you are contributing a new file, please prepend the following license header

Make sure lines never exceed 80 columns in width when using four-character
indentation steps. This helps contributors with smaller screens, those using
side-by-side editor windows or panes, and those who have no text wrapping in
their editor or terminal.

For usage text and help messages, do not implement a -h option. Instead, print
usage information when any erroneous option is specified. Follow the NetBSD
style guide for the usage text’s output format [1].
