File: Help.c

Abstract: Sets help tags for the preferences window and preferences dialog.

Version: 6.0

Change History:

    <6.0>   this file is now only necessary in the PEF version 

            (because the Mach-O version now uses nibs which have the 

            help tags included)

    <5.0>   renamed InstallPrefsWindowHelpTags to 

            SetPrefsWindowHelpTags which just sets help tags on the 

            window's controls

            removed DisposePrefsWindowHelpTags and 

            displayPrefsWindowHelpTags

    <4.0>   removed all Classic code

            removed CalculateBalloonHelpRects and DisplayHelpBalloons

    <3.0>   no changes necessary

    <2.0>   added support for help tags

            this was a bit of a chore for the preferences window 

            because of the list

    <1.0>   first release version
