=head2 ENVIRONMENT AND REGISTRY
=over 6
Most settings can be made for a user and for the system. User
settings override system settings.
For admin users, the functions below affect both user- and system
settings. For non-admin users, only user settings are changed.
An exception is the search path: the effective searchpath consists
of the system searchpath in front concatenated with the user
searchpath at the back.
Note that in a roaming profile network setup, users take only user
settings with them to other systems, not system settings. In this
case, with a TeXLive on the network, a nonadmin install makes the
most sense.
