.SH "NAME"
dtdflatten \- Flatten an SGML/XML DTD.
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
.Vb 1
\&  dtdflatten [options]
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBdtdflatten\fR parses a \s-1DTD\s0 and prints out a flatten/expanded version
of it with all parameter entities expanded.
.PP
The first non-option-related argument provided on the command-line
specifies the file to parse.  If no filename is given, then the
\&\s-1DTD\s0 is read from standard input.
.PP
The flatten \s-1DTD\s0 is printed to standard output unless
the \f(CW\*(C`\-\-output\*(C'\fR option is specified.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\-\-catalog <catalog>" 4
.IX Item "--catalog <catalog>"
Specify catalog files to parse for resolving external entity
references.  This option can be specified multiple times.
.Sp
\&\fB\s-1NOTE:\s0\fR Currently, only \s-1SGML\s0 Open Catalog format is supported.
\&\s-1XML\s0 Catalog support is not implemented (yet).
.IP "\-\-debug" 4
.IX Item "--debug"
Extra debugging output.  This option can be specified multiple
times to increase the amount of output.
.Sp
Debugging output is sent to standard error.
.IP "\-\-declaration <file>" 4
.IX Item "--declaration <file>"
Specify the \s-1SGML\s0 declaration.  The \s-1SGML\s0 declaration is parsed
to determine the type of \s-1DTD\s0 being parsed, \s-1XML\s0 or \s-1SGML.\s0  The
key parts of the \s-1SGML\s0 declaration examined are the \s-1NAMECASE\s0
and \s-1CHARSET\s0 directives to determine the \s-1DTD\s0 type.
.Sp
If no \s-1SGML\s0 declaration is available, the \f(CW\*(C`\-\-xml\*(C'\fR,
\&\f(CW\*(C`\-\-namecase\-general\*(C'\fR, and \f(CW\*(C`\-\-namecase\-entity\*(C'\fR options can
be used.
.IP "\-\-output <file>" 4
.IX Item "--output <file>"
Output file.  If not specified, standard output is used.
.IP "\-\-preserve <entity\-name>" 4
.IX Item "--preserve <entity-name>"
Preserve parameter entity declaration denoted by <entity\-name>.  This
option can be specified multiple times.
.Sp
Note, if <entity\-name> matches any portion of a parameter entity,
the parameter entity declaration will be preserved.
.IP "\-\-verbose" 4
.IX Item "--verbose"
.PD 0
.IP "\-\-noverbose" 4
.IX Item "--noverbose"
.PD
Print parsing progress.  By default, this option is enabled.
Verbose output is sent to standard error.
.Sp
If \f(CW\*(C`\-\-debug\*(C'\fR is specified, then this option is automatically
enabled.
.IP "\-\-version" 4
.IX Item "--version"
Print version and synopsis.
.IP "\-\-help" 4
.IX Item "--help"
Print synopsis and options available.
.IP "\-\-man" 4
.IX Item "--man"
Print manual page.
