In particular, Do* should encapsulate the "current wisdom" of the best approach for colorizing an otherwise unknown interpress master.fromFile, toFile are file namespalette is a Profile which will be queried for color and rendering informationcheckSystemSetting is a way to check settings maintained by the system.Suggestion To Clients:  If there is a route for a user-specific or document-specific Profile, we suggest that this be layered over both the palette profile and checkSystemSetting so that  both color and control info can be changed per document.fromIP, toIP are ROPEs containing the interpress tokens.  They include the headers.Do  (and DoRope) guarantee that they will not call checkSystemSetting with a ROPE which is not in ExaminesTheseSettings[], allowing clients of ColorizeViewPoint to know the universe of possible options.The defaults returned in these settings are not used anywhere except to return to the client from ExaminesTheseSettings.ÊÁ  ˜ ™Icode™BK™)K™*K™ —šÏk	˜	Kšœ	œ˜Kšœœœ˜K˜ —K˜ KšÐlnœœ˜$šœ˜K˜ Kšœœœ˜K˜ KšÏnœœ	œœ˜1šŸœœ	œœ˜.K™HKšœœ™:Kšœœ	™*K˜ —Kš	Ïbœ œ œR Ðbuœt™ñK™ šŸœœœI˜iKšœ™K™NKšœG™GKš œ† œU™ôK˜ —š
