=head1 NAME

pod2hlb - pod library to VMS help library converter.

=head1 SYNOPSIS

    edit pod2hlb.
    perl pod2hlb

=head1 DESCRIPTION

This is an extremely simple program that merely
converts the PERL_ROOT:[lib.pod]*.pod,*.pm files into
*.hlp files using the Pod::Hlp module.  It then 
adds all the resultant .hlp files to a PERL.HLB 
library in the DEFAULT directory.  You are strongly
encouraged to modify the code to suit your personal
preferences and/or local pod locations.

Since this program invokes the LIBRARIAN it
is unlikely to work on non-VMS systems.  For that
reason is uses RMS style file specifications internally.

=head2 Installation

The resultant *.HLP files could be added directly to the
system default help file (usually SYS$HELP:HELPLIB.HLB).
Alternatively, you may retain PERL.HLB as a separate 
library and install it via either copying to SYS$HELP 
and invoking help via:

    HELP/LIBRARY=PERL

or by defining a HLP$LIBRARY logical name such as one 
of the following:

    define HLP$LIBRARY PERL_ROOT:[lib.pod]perl

or, if HLP$LIBRARY is already defined add an underscore 
and integer _n such as:

    define HLP$LIBRARY_1 PERL_ROOT:[lib.pod]perl

see HELP HELP and HELP LIBRARY for further details.
