While we are at it, I'd like to point out that the recent work on 
math fonts also produced a few small extensions to fontinst (by 
Matthias Clasen) which facilitate writing .etx and .mtx files.  
It would be nice if those extensions, at least the essential ones,
could find their way into the primary fontinst distrubtion as well.

As for documentation, the code below allows to write something like

  \useexamplefont{<font_containing_new_symbols>}

  \setdefaultslotcomment{The symbol `\slotexample'.}
  \setslot{<some_symbol>}\endsetslot
  \setslot{<another_symbol>}\endsetslot
  \setslot{<some letter>}[The letter `\slotexample'.]\endsetslot
  \setslot{<yet_another_symbol>}\endsetslot

instead of the more tedious

  \usepackage{<package_to_access_symbols>}

  \setslot{<some_symbol>}
     \comment{The symbol `$\somesymbol$'.}
  \endsetslot
  \setslot{<another_symbol>}
     \comment{The symbol `$\anothersymbol$'.}
  \endsetslot
  \setslot{<some_symbol>}
     \comment{The letter `\letter'.}
  \endsetslot

I hope the basic idea of this should be clear.

Cheers, Ulrik,
