/*
* shpolicy.c - Data for shell/system policies.
*
* Created 1999 by Ian Schmidt <ischmidt@cfl.rr.com>
*
* Some of these policies can be tweaked via the System Policy
* Editor which came with the Win95 Migration Guide, although
* there doesn't appear to be an updated Win98 version that
* would handle the many new policies introduced since then.
* You could easily write one with the information in
* this file...
*
* Up to date as of SHELL32 v4.72 (Win98, Win95 with MSIE 5)
