const (
	PrivilegeRead             = 1 << iota // used to be to fetch public data, such as user information etc. this is deprecated.

	PrivilegeWrite                        // change user information, write into confidential stuff...
	PrivilegeManageBadges                 // can change various users' badges.

	PrivilegeManageRoles                  // translates as admin, as they can basically assign roles to anyone, even themselves
	PrivilegeManageAPIKeys                // admin permission to manage user permission, not only self permissions. Only ever do this if you completely trust the application, because this essentially means to put the entire ripple database in the hands of a (potentially evil?) application.
	PrivilegeBlog                         // can do pretty much anything to the blog, and the documentation.
	PrivilegeAPIMeta                      // can do /meta API calls. basically means they can restart the API server.
	PrivilegeBeatmap                      // rank/unrank beatmaps. also BAT when implemented
	PrivilegeBancho                       // can log in to bancho and use the chat through the delta ws api
)

These are the various privileges a token can have.
