//! The Ambassador Program.
//!
//! The module defines the following on-chain functionality of the Ambassador Program:
//!
//! - Managed set of program members, where every member has a [rank](ranks)
//! (via [AmbassadorCollective](pallet_ranked_collective)).
//! - Referendum functionality for the program members to propose, vote on, and execute
//! proposals on behalf of the members of a certain [rank](Origin)
//! (via [AmbassadorReferenda](pallet_referenda)).
//! - Managed content (charter, announcements) (via [pallet_collective_content]).
//! - Promotion and demotion periods, register of members' activity, and rank based salaries
//! (via [AmbassadorCore](pallet_core_fellowship)).
//! - Members' salaries (via [AmbassadorSalary](pallet_salary), requiring a member to be
//! imported or inducted into [AmbassadorCore](pallet_core_fellowship)).
