# 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.
|
|
# Version 1.02 Roderick Schertler <roderick@argon.org>
|
|
# Check for pod directives following any kind of unempty line, not
|
|
# just lines of whitespace.
