+# This script uses the Linux 'indent' utility to re-format C source files
+# to match the coding style that I use.  It differs from my coding style in that
+#
+# - I normally put the trailing */ of a multi-line comment on a separate line,
+# - I usually align things vertically (like '=' in assignments),
+# - indent puts a bogus blank line at the top of the file,
+# - I don't like the way it handles nested conditional compilation intermixed with code.
