41 | # Subject: POD lines with only spaces | |
2862e1b7 | 42 | # |
f31caa63 | 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. | |
36816da2 | 51 | # Version 1.01 Andy Dougherty <doughera@lafayette.edu> |
f31caa63 | 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. | |
