github repo to port connection

[Athanasios Douitsis]

Hello,

Totally new to ports maintenance, please bear.

Is there a way for a port to be semi-automatically updated from a github
repo as its source?

I understand that a ports committer (which I am not) must always be present
in the process, just looking for the optimal way to handle maintenance.

If this has been discussed before, my apologies.

Many thanks,
