How to get around changing .i files while indexing offline

Oh Dear! The joys of working late. If was talking about SRS6.x. I'm sorry
for the previous posting.

However, a judicious use of the environment variable that determine where
the index and icarus files are as well as building the srs section somewhere
else can do the trick with SRS5.x. Thure and I did it here a while back
during an emergency and it worked. It required quite a lot of cool (real
sweat!) from my part to go through it :-) It can get quite complicated and
this is indeed what has appeared 'transparently' in SRS6.x
