OpenSSL::Util::Pod - utilities to manipulate .pod files

=head1 SYNOPSIS
|
|
|
|
use OpenSSL::Util::Pod;
|
|
|
|
my %podinfo = extract_pod_info("foo.pod");
|
|
|
|
# or if the file is already opened... Note that this consumes the
|
|
# remainder of the file.

|
|

my %podinfo = extract_pod_info(\*STDIN);

=head1 DESCRIPTION
|
|
|
|
=over
|
|
|
|
=item B<extract_pod_info "FILENAME", HASHREF>
|
|
|
|
=item B<extract_pod_info "FILENAME">
|
|
|
|
=item B<extract_pod_info GLOB, HASHREF>
|
|
|
|
=item B<extract_pod_info GLOB>
|
|
|
|
Extracts information from a .pod file, given a STRING (file name) or a
|
|
GLOB (a file handle). The result is given back as a hash table.
|
|
|
|
The additional hash is for extra parameters:
|
|
|
|
=over
|
|
|
|
=item B<section =E<gt> N>
|
|
|
|
The value MUST be a number, and will be the man section number
|
|
to be used with the given .pod file.
|
|
|
|
=item B<debug =E<gt> 0|1>
|
|
|
|
If set to 1, extra debug text will be printed on STDERR

=head1 RETURN VALUES
|
|
|
|
=over
|
|
|
|
=item B<extract_pod_info> returns a hash table with the following
|
|
items:
|
|
|
|
=over
|
|
|
|
=item B<section =E<gt> N>
|
|
|
|
The man section number this .pod file belongs to. Often the same as
|
|
was given as input.
|
|
|
|
=item B<names =E<gt> [ "name", ... ]>
|
|
|
|
All the names extracted from the NAME section.
