+% Recent versions of luatex kindly provide a process_jobname callback for
+% this. Detect if it is available and use a fallback in pure TeX otherwise.
+% If using the callback, register it at \everyjob time since callbacks are not
+% dumped in formats currently.
+%
+% The TeX version fails with "luatex '\input foo'" invocations, but it can
+% either support that or spaces in filenames, not both. This one is kept for
+% historical reasons.
+%
+% This file is inputed after latex.ltx.
