Best way to get submodules into extracted source?

Thank you. this indeed works for transmission-x11 but not for transmission, because the release tarball only has some of the submodules. Maybe I’ll ask the dev to see if he can provide a complete one.

I found the macports guide reads "the best distfile candidate (if available) is a distfile from GitHub releases”, so I’d like to know what’s the best way to put submodules into the extracted tarball, without using `fetch.type git` and `git submodule update —init`. Would be great if there’s a port already doing this so I could learn from it.
