Comment (by Zweihorn):

 Got you apparently ... ;)

 > New section on 'subport'
 >
 > AFAIK the [https://guide.macports.org/#development Chapter 4. Portfile
 Development] lacks sufficient documentary on the 'subport' excellent
 opportunities both for new Portfile development and port mainentance,
 unfortunately.

 [https://github.com/macports/macports-guide/pull/53  macports-guide: adoc/
 content list #53]

 However, supposedly we could discuss if I ever can become the person
 writing this documentation. At your deliberation naturally.
