+# This script converts legacy layout files as understood by flashrom up to version 0.9.7 to format version 2.0.
+# It converts all files given as parameters in place and creates backups (with the suffix ".old") of the old
+# contents unless --nobackup is given.
+#
+# It does...
+# - check if the file format is already in 2 format
+# - prefix addresses with 0x if they have not been already
+# - remove superfluous white space (i.e. more than one consecutive space)
+# - remove white space from otherwise empty lines
