dac2pm - Generating Perl Module from "dac" File

=head1 SYNOPSIS

  perl path/to/dac2pm.pl input.dac \
            --module-uri=module-uri [--for=for-uri] [options] > ModuleName.pm
  perl path/to/dac2pm.pl input.dac \
            --module-uri=module-uri [--for=for-uri] [options] \
            --output-file-path=ModuleName.pm
  perl path/to/dac2pm.pl input.dac \
            --create-perl-module="module-uri ModuleName.pm [for-uri]" \
            [--create-perl-module="..." ...]
  perl path/to/dac2pm.pl --help

=head1 DESCRIPTION

The C<dac2pm.pl> script generates Perl modules from a "dac" database file
created by C<dac.pl>.

This script is part of manakai.

=head1 OPTIONS

=over 4

=item --enable-assertion / --noenable-assertion (default)

Whether assertion codes should be outputed or not. 

=item --create-perl-module="I<module-uri> I<ModuleName.pm> [I<for-uri>]" (Zero or more)

The C<--create-perl-module> option can be used to specify
I<--module-uri>, I<--output-file-path>, and I<--for> options
once.  Its value is a space-separated triplet of "dis" module name URI,
Perl module file path (environment dependent), and optional
"dis" module "for" URI.

This option can be specified more than once; it would
make multiple Perl module files to be created.  If 
both I<--module-uri> and this options are specified,
I<--module-uri>, I<--output-file-path>, and I<--for>
options are treated as if there is another I<--create-perl-module>
option specified.

=item --for=I<for-uri> (Optional)

Specifies the "For" URI reference for which the outputed module is. 
If this parameter is ommitted, the default "For" URI reference 
for the module specified by the C<dis:DefaultFor> attribute
of the C<dis:Module> element, if any, or C<ManakaiDOM:all> is assumed. 

=item --help

Shows the help message. 

=item --module-uri=I<module-uri>

A URI reference that identifies a module from which a Perl
module file is generated.  This argument is I<required>.

=item --output-file-path=I<perl-module-file-path> (default: the standard output)

A platform-dependent file path to which the Perl module
is written down.

=item C<--output-line> / C<--nooutput-line> (default: C<--nooutput-line>)

Whether C<#line> directives should be included to the generated
Perl module files.

=item --verbose / --noverbose (default)

Whether a verbose message mode should be selected or not.
