perl 5.003_05: dev/null

New script to check for common errors in pods.  This is not
normally called during the perl build process, but you can
use it with  B<make check>.

+# Subject: POD lines with only spaces
+# 
+# There are some places in the documentation where a POD directive is
+# ignored because the line before it contains whitespace (and so the
+# directive doesn't start a paragraph).  This patch adds a way to check
+# for these to the pod Makefile (though it isn't made part of the build
+# process, which would be a good idea), and fixes those places where the
+# problem currently exists.
+#
+#  Version 1.00  Original.
+#  Version 1.01  Andy Dougherty <doughera@lafcol.lafayette.edu>
+#    Trivial modifications to output format for easier auto-parsing
+#    Broke it out as a separate function to avoid nasty
+#      Make/Shell/Perl quoting problems, and also to make it easier
+#      to grow.  Someone will probably want to rewrite in terms of
+#      some sort of Pod::Checker module.  Or something.  Consider this
+#      a placeholder for the future.
