!UpdateSys
----------

This application upgrades !System applications from RISC OS 3.5 and below. 
Just run it.  That's all there is.  It just makes sure the module search
paths are in the proper order; previous to RISC OS 3.6, !System only had one
modules folder.  Then Acorn changed to a more sensible scheme where we have
one Modules folder for each version of the OS, so that modules which only
worked on a particular version and above could be separated from those for
previous versions of the OS.

The upgrade involves creating the new folders in !System and copying a
utility to set the paths properly, supplied courtesy of Acorn. It then
concatenates the newest Toolbox modules in the right place, before updating
any that are too old for PCPro, and adding a utility to your boot sequence
which unplugs any in ROM that are too old. You should reboot after running
!UpdateSys if it made any changes.
