+# Makefile to build XZ Utils using DJGPP
+#
+# Make flags to alter compilation:
+#
+#   DEBUG=1     Enable assertions. Don't use this for production builds!
+#               You may also want to set CFLAGS="-g -O0" to disable
+#               optimizations.
+#
+# The usual CPPFLAGS and CFLAGS are supported too.
