+# This Makefile assumes that you have MinGW installed under /usr

+# built/installed libogg, Tremor, libpng16, SDL2 ad SDL2_ttf under
+# __ /usr/local __ (not /usr!) in similar fashion.
+#
+# For differing configurations you will have to either edit this
+# file or alternatively provide make parameters, e.g.

+# make -f Makefile.cross-mingw MINGW=64 BINTOOL_PREFIX=foo-bar-zoo
