41 # Subject: POD lines with only spaces
43 # There are some places in the documentation where a POD directive is
44 # ignored because the line before it contains whitespace (and so the
45 # directive doesn't start a paragraph). This patch adds a way to check
46 # for these to the pod Makefile (though it isn't made part of the build
47 # process, which would be a good idea), and fixes those places where the
48 # problem currently exists.
50 # Version 1.00 Original.
51 # Version 1.01 Andy Dougherty <doughera@lafcol.lafayette.edu>
52 # Trivial modifications to output format for easier auto-parsing
53 # Broke it out as a separate function to avoid nasty
54 # Make/Shell/Perl quoting problems, and also to make it easier
55 # to grow. Someone will probably want to rewrite in terms of
56 # some sort of Pod::Checker module. Or something. Consider this
57 # a placeholder for the future.
58 # Version 1.02 Roderick Schertler <roderick@argon.org>
59 # Check for pod directives following any kind of unempty line, not
60 # just lines of whitespace.
