[Koha] upgrading

[Ramon Andinach]

Hi,

Its beginning to sound like there are enough changes in the Koha beta  
that its worth doing an upgrade. I was scanning through the INSTALL  
file for the "right way" to do this and noticed this line:

perl Makefile.PL --prev-install-log /path/to/koha-install-log

which I assume is a way of me avoiding having to remember what I  
answered for all the install questions before.

The only problem is I can't find it. Does anyone know where this file  
is usually put?
