mkdisdump.pl - Generating Perl Module Documentation Source

=head1 SYNOPSIS

  perl path/to/mkdisdump.pl input.cdis \
            {--module-name=ModuleName | --module-uri=module-uri} \
            [--for=for-uri] [options] > ModuleName.pm
  perl path/to/cdis2pm.pl --help

=head1 DESCRIPTION

The C<cdis2pm> script generates a Perl module from a compiled "dis"
("cdis") file.  It is intended to be used to generate a manakai 
DOM Perl module files, although it might be useful for other purpose. 

This script is part of manakai.

=head1 OPTIONS

=over 4

=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, if any, or the C<ManakaiDOM:all> is assumed. 

=item --help

Shows the help message. 

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

A URI reference that identifies a module to output.  Either 
C<--module-name> or C<--module-uri> is required. 

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

Whether a verbose message mode should be selected or not. 

=item --with-implementators-note / --nowith-implementators-note (default)

Whether the implemetator's notes should also be included
in the result or not.
