+# The difference between this PKGBUILD and the one from `emacs-git` is that:
+# - this one builds emacs from `feature/native-comp` branch.
+# - built-in packages are native compiled by default.
+# - link-time optimization is disabled by default.
+#
+# Pre-compiling all built-in elisp modules takes *hours* on fast systems. You
+# can set FAST_BOOT="YES" to pre-compile the bare minimum, then you'll need to
+# manage native-compilation later (eg. with comp-deferred-compilation).

 # CAVEAT LECTOR: This PKGBUILD is highly opinionated. I give you
 #                enough rope to hang yourself, but by default it
 #                only enables the features I use.
