+# This wrapper works around fontmake's limitation (at the time of this writing)
+# of not being able to specify the output directory for the generated font
+# binaries. The Meson build system's custom target function has fixed
+# expectations about where files must show up. Also, autohint the binaries
+# while we're at it.
