+If you're interested in applying patches but aren't working with a
+public-inbox instance, it's still possible to use piem (see the
+documentation).  However, in this case, you may want to consider
+mailscripts (https://git.spwhitton.name/mailscripts/), a "collection
+of scripts for manipulating e-mail on Debian".  Its
+notmuch-extract-patch script (accessible via Emacs commands) provides
+an alternative to b4 for extracting a patch series from a thread.
+
+And if you're searching for an Emacs interface for *sending* patches,
+take a look at git-email (https://sr.ht/~yoctocell/git-email/).
