+# Usage: cpp-cc --cpp=CPP CC ... file.S ...
+#
+# Process file.S with the given CPP command plus any -D options in the
+# rest of the arguments, then assemble with the given CC plus all
+# arguments.
+#
+# The CPP command must be in a single --cpp= argument, and will be
+# split on whitespace.  It should include -I options required.
+#
+# When CC is invoked, file.S is replaced with a temporary .s file
+# which is the CPP output.
+#
+# Any lines starting with "#" are removed from the CPP output, usually
+# these will be #line and #file markers from CPP, but they might also
+# be comments from the .S.
+#
+# To allow parallel builds, the temp file name is based on the .S file
+# name, which will be the output object filename for all uses we put
+# this script to.
