- =head1 NAME
-
- Pod::Simple::Checker -- check the Pod syntax of a document
-
- =head1 SYNOPSIS
-
- perl -MPod::Simple::Checker -e \
- "exit Pod::Simple::Checker->filter(shift)->any_errata_seen" \
- thingy.pod
-
- =head1 DESCRIPTION
-
- This class is for checking the syntactic validity of Pod.
- It works by basically acting like a simple-minded version of
- L<Pod::Simple::Text> that formats only the "Pod Errors" section
- (if Pod::Simple even generates one for the given document).
-
- This is a subclass of L<Pod::Simple> and inherits all its methods.
-
- =head1 SEE ALSO
-
- L<Pod::Simple>, L<Pod::Simple::Text>, L<Pod::Checker>
