(p [
This chapter describes the facilities Skribe offers authoring slides.
In order to access the functionalities described in this chapter, it
is require to introduce a ,(code [(skribe-load "slides.skr")]) expression
at the beginning of the document. The Slide package supports two
,(markup-ref "skribe-load") user options: ,(param :advi) and ,(param :prosper).
The first one tells Skribe to generate slides for the Advi presenter. The
second one tells Skribe to generate slides for the LaTeX prosper package.])
