dthelp_htag2(1)

     NAME
          dthelp_htag2 - second pass for parse of HelpTag source

     SYNOPSIS
             dthelp_htag2  -[cdhot] file [outfile]

     DESCRIPTION
          The dthelp_htag2 executable is invoked by dthelptag(1) as
          the second pass of translating HelpTag markup into SDL.

          The dthelp_htag2 executable accepts the output of the first
          pass of dthelptag (either dthelp_htag1(1) or
          dthelp_ctag1(1)) and computes the byte offsets of virtual
          pages to be used in the runtime display of the SDL volume.

          If only one file is specified on the command line, the
          output file will overwrite the input file.  If two files are
          specified, the output will be placed in the second.

          If the input file has no .sdl extension, one will be added.
          If a second file name is specified for output, it will be
          used without modification.

          The options to dthelp_ctag2 are:

             -c:            compress the SDL document on a per virtual
                            page basis - if the document is already
                            compressed, this command will result in no
                            change to the document.

             -d:            decompress an SDL document - if the
                            document is already compressed, this
                            command will result in no change to the
                            document; however, the byte offsets of
                            virtual pages will be recomputed.

             -h:            print a help message and exit.

             -o:            perform peephole optimization of the SDL
                            document.  In particular, <FORM> elements
                            containing only a single <BLOCK> or <FORM>
                            without a user supplied identifier are
                            replaced by that single <BLOCK> or <FORM>
                            with the identifier of the original
                            (outer) <FORM>.

             -t:            eliminate any <TOSS> sub-elements that are
                            not used in this SDL document.
