# From: Roderick Schertler <roderick@gate.net>
# To: perl5-porters@africa.nicoh.com
# 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@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.
@directive = qw(head1 head2 item over back cut pod for begin end);
