NAME

       dtdflatten - Flatten an SGML/XML DTD.

SYNOPSIS

         dtdflatten [options]

DESCRIPTION

       dtdflatten parses a DTD and prints out a flatten/expanded version of it with all parameter
       entities expanded.

       The first non-option-related argument provided on the command-line specifies the file to
       parse.  If no filename is given, then the DTD is read from standard input.

       The flatten DTD is printed to standard output unless the "--output" option is specified.

OPTIONS

       --catalog <catalog>
           Specify catalog files to parse for resolving external entity references.  This option
           can be specified multiple times.

           NOTE: Currently, only SGML Open Catalog format is supported.  XML Catalog support is
           not implemented (yet).

       --debug
           Extra debugging output.  This option can be specified multiple times to increase the
           amount of output.

           Debugging output is sent to standard error.

       --declaration <file>
           Specify the SGML declaration.  The SGML declaration is parsed to determine the type of
           DTD being parsed, XML or SGML.  The key parts of the SGML declaration examined are the
           NAMECASE and CHARSET directives to determine the DTD type.

           If no SGML declaration is available, the "--xml", "--namecase-general", and
           "--namecase-entity" options can be used.

       --output <file>
           Output file.  If not specified, standard output is used.

       --preserve <entity-name>
           Preserve parameter entity declaration denoted by <entity-name>.  This option can be
           specified multiple times.

           Note, if <entity-name> matches any portion of a parameter entity, the parameter entity
           declaration will be preserved.

       --verbose
       --noverbose
           Print parsing progress.  By default, this option is enabled.  Verbose output is sent
           to standard error.

           If "--debug" is specified, then this option is automatically enabled.

       --version
           Print version and synopsis.

       --help
           Print synopsis and options available.

       --man
           Print manual page.
