41 | # Subject: POD lines with only spaces |
---|
42 | # |
---|
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. |
---|
49 | # |
---|
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. |
---|
