'92 S4, Changing timing belt

[vilr@jupiter.sun.csd.unb.ca (Pierre Villiard)]

Hi all,
  This is one of the liveliest and most interesting list I have subscribed
to. Thanks for the welcome words and all the info on everything.
  To the point: Are there special tools needed to change the timing belt on
a '92 S4? (Now, Eric, don't tell me I need many!)
  I would appreciate a precise description, if possible... because there
may be a little job for a machinist here.
  Besides, is it conceivable to use one of Paul W.'s or Bob D.'s "ways
around the puller for the crank nut" in this case, without making the Gods
very angry?
  Thanks in advance,

Pierre
