[3/3] meson: wire up the git-subtree(1) command

Commit Message

Patrick Steinhardt Jan. 17, 2025, 9:56 a.m. UTC

Wire up the git-subtree(1) command, which is part of "contrib/". Note
that we have to move around the exact location where we include the
"contrib/" subdirectory so that it comes after building the docs so that
we have access to some of the common functionality.
