+---------
+
+  I am embarassed that this is here.  This program is a complete hack
+  but, unfortunately, it has become so useful to me that I need to keep
+  it here.
+
+  A little background:  I have tinkered with pretty printers for some
+  time and have not been happy with the results.  An alternative that
+  occurred to me would be just a standard checker that examines a C
+  file that gives warnings for violations of the coding standard.
+
+  This turns out to be more difficult that you might think. A pretty
+  printer understands C syntax:  They break the file up into its C
+  components then reassembles the output in the format. But parsing the
+  C loses the original file layout and so it not useful in this case.
+
+  This program instead, uses a collection of heuristics (i.e., hacks and
+  bandaids) to examine the C file for obvious violations of the coding
+  standard.  This program is completely ignorant of C syntax; it simply
+  performs crude pattern matching to check the file.
+
+  Usage: nxstyle <path-to-file-to-check>
