+# Usage: m4-ccas --m4=M4 CC ... file.asm ...
+#
+# Process file.asm with the given M4 plus any -D arguments, then
+# assemble with the given CC plus all arguments.
+#
+# The M4 command must be in a single --m4= argument, and will be split
+# on whitespace. When CC is invoked file.asm is replaced with a
+# temporary .s file which is the M4 output.
+#
+# To allow parallel builds, the temp file name is based on the .asm
+# file name, which will be the output object filename for all uses we
+# put this script to.
