=head1 NAME

cdis2pm - Generating Perl Module from a Compiled "dis"

=head1 SYNOPSIS

  perl path/to/cdis2pm.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 --enable-assertion / --noenable-assertion (default)

Whether assertion codes should be outputed or not. 

=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-name=I<ModuleName>

The name of module to output.  It is the local name part of 
the C<Module> C<QName> in the source "dis" file.  Either 
C<--module-name> or C<--module-uri> is required. 

=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 --output-file-path=I<perl-module-file-path> (default: C<STDOUT>)

A platform-dependent file name path for the output.
If it is not specified, then the generated Perl module
content is outputed to the standard output.

=item --output-module-version (default) / --nooutput-module-version

Whether the C<$VERSION> special variable should be generated or not. 

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

Whether a verbose message mode should be selected or not.
