37 # From: Roderick Schertler <roderick@gate.net>
38 # To: perl5-porters@africa.nicoh.com
39 # Subject: POD lines with only spaces
41 # There are some places in the documentation where a POD directive is
42 # ignored because the line before it contains whitespace (and so the
43 # directive doesn't start a paragraph). This patch adds a way to check
44 # for these to the pod Makefile (though it isn't made part of the build
45 # process, which would be a good idea), and fixes those places where the
46 # problem currently exists.
48 # Version 1.00 Original.
49 # Version 1.01 Andy Dougherty <doughera@lafcol.lafayette.edu>
50 # Trivial modifications to output format for easier auto-parsing
51 # Broke it out as a separate function to avoid nasty
52 # Make/Shell/Perl quoting problems, and also to make it easier
53 # to grow. Someone will probably want to rewrite in terms of
54 # some sort of Pod::Checker module. Or something. Consider this
55 # a placeholder for the future.
