 /* Htmshell.h - stuff to make it easier to generate HTML files on
  * the fly.  Typically included with cheapcgi.h in almost any
  * CGI program.
  *
  * To use this generally you should call the function htmShell()
  * very early inside of main().  You pass htmShell() a routine
  * which does most of the work of your web server-side applet.
  *
  * These routines will throw errors, which are caught by
  * htmShell, which then returns.  For the most part you just
  * want an error to cause an error message to be printed and
  * then terminate your CGI program, so this works fine.
