conflict resolution may be used to good effect to correct problems
without undue amounts of programmer intervention.</P

clear the check boxes against the resolutions for each proposed
resolution. By default all resolutions are selected; you can return
to the default state (in other words, cause all check boxes for
each conflict to again become checked) by pressing the &#8220;Reset&#8221; button.
Note that multiple selection may be used in the resolutions control
to allow ranges of check boxes to be toggled in one gesture.</P

conflict displayed, click <SPAN

apply the resolutions. Alternatively you may cancel from the dialog
box without any resolutions being applied.</P
