Usage: $name [-a] [-b] [-h] [-s] [-u] <string>
This program provides command-line access to the PDL documentation.
If no flag is specified, -h is assumed.
-a (apropos) searches the documentation for the string
-b (badinfo) does the function support bad values?
-h (help) prints the help for the function/module/document
-s (sig) prints the signature of the function
-u (usage) gives usage information on the function

pdldoc - shell interface to PDL documentation
=head1 SYNOPSIS
B<pdldoc> <text>
=cut
B<pdldoc> [B<-a>] [B<-b>] [B<-h>] [B<-s>] [B<-u>] <text>
=head1 DESCRIPTION
The aim of B<pdldoc> is to provide the same functionality
as the C<apropos>, C<help>, C<sig>,
=cut
C<badinfo>,
and C<usage> commands available in the L<perldl|PDL::perldl>
and L<pdl2|pdl2> shells.
Think of it as the PDL equivalent of C<perldoc -f>.
=head1 OPTIONS

=item B<-h> help

This is the default option.
=item B<-a> apropos
Regex search PDL documentation database.
=cut
=item B<-b> badinfo
Information on the support for bad values provided by the function.
=cut
=item B<-s> sig
prints signature of PDL function.
=item B<-u> usage
Prints usage information for a PDL function.
=item C<$PDL::Config{PDLDOC_IGNORE_AUTOLOADER}>
This PDL configuration variable may be set in the perldl.conf
file to disable runtime search for documentation in
L<PDL::AutoLoader|PDL::AutoLoader> files.
