The <ProfilePages> option is used to modify the individual profile pages.

You can use this option to assign commentaries to specified individuals. Commentaries can be used to include text on an individual's profile page under the Detail tab. Commentaries are different than regular notes which appear on individual's profile page under the Notes tab. The purpose of a commentary is to provide introductory information for an individual, especially as it applies to the status of the individual's ancestry. As such, when a commentary exists for an individual who does not have parents, and when that individual appears on an ancestor list or a descendant list, the commentary will be link as a popup under a colorful help icon. Gigatrees5 will also recognize standard GEDCOM NOTE records for individuals where the NOTE record contains the translatable text [Commentary]. In this case, the text will be stripped so that it does not appear in the displayed commentary.
