What does "synopsis" mean?

Synopsis: A general view, or a collection of heads or parts so arranged as to exhibit a general view of the whole; an abstract or summary of a discourse; a syllabus; a conspectus. That the reader may see in one view the exactness of the method, as well as force of the argument, I shall here draw up a short synopsis of this epistle. Bp. Warburton. See Abridgment.
