+Usage: $progname [OPTIONS]
+
+Replace the multilib-unclean header file with multilib-clean stub, while the
+original file is moved to unique architecture-specific location.  This should be
+absolutely safe operation (effects of '#include <HEADER.h>' are unchanged.
+
+To allow us to do incompatible changes in this script, packagers should use this
+script only through %ml_fix_c_header wrapping macro.
+
+--destdir       absolute path name where the old header file is stored, e.g.
+                /some/pat
+--basename      when you deal with '/some/path/test.h', specify 'test'
+--buildroot     prefix (directory where we play with installed files, usually
+                after 'make install DESTDIR=buildroot')
+--additional-suffix     we usually move 'test.h' to 'test_\$ARCH.h'.  However
+                this file could already exit.  With this option the multilib
+                file will be named 'test_\$ARCH\$SUFFIX.h'
