+From 17049393c60503d305787d06b7137227a99ed2af Mon Sep 17 00:00:00 2001

+Subject: [PATCH] Improve Makefile to avoid "Argument list too long" error
+
+I wouldn't expect a foreach loop to be prone to this issue but it's
+not the right way to write a Makefile anyway.
+
+Note that conversion failures are now fatal and the dvb-t/ke-Nairobi
+file is failing to convert at the moment.
