## # <https://www.octave.org>
Text that is within these angles and separated by at least one space from the URL is a displayed text for the link.
## # <https://www.octave.org GNU Octave>
A link starting with ‘<octave:’ followed by the name of a GNU Octave function, optionally with a displayed text, results in a link to the online GNU Octave documentations function index.
