    1.10 +Notes       :
    1.11 +   
    1.12 +   Profiles are used to store per-user settings that can be transferred and used
    1.13 +   across multiple applications.  For example, player IPD can be configured once 
    1.14 +   and reused for a unified experience across games.  Configuration and saving of profiles
    1.15 +   can be accomplished in game via the Profile API or by the official Oculus Configuration
    1.16 +   Utility.
