in DefinitelyTyped, there is an existing build and test scheme. In prior releases of our angular2.d.ts I've had to manually work around some things:

• dgeni includes the generic type parameter as a member (eg. classes start with T;)
• TS 1.4: destructured args have to be rewritten as a named interface
• TS 1.4: change const to var
• comply with noImplicitAny: add return types and type missing stuff as any

note that DT should start accepting TS 1.5 after the official release: see DefinitelyTyped/DefinitelyTyped#4564
