Remarks:

comphelp.red

   analyse the tex input structure,
   build indices and hypertext links on logical level

helpunx.red

   controlled by comphelp.red,
   build indices and hypertext links for GNU info format.
   NOTE: the process comphelp.red/helpunx.red must run twice
         in one session, as forward links have to be
         generated.

helpwin.red

   controlled by comphelp.red,
   build indices and hypertext links in Microsoft RTF syntax

mkhelpu: UNIX cshell script for producing rhelp.info

mkhelpw: UNIX cshell script for producing rhelp.rtf
       (MS help compiler can run under DOS only).
