A presentation (or a slide-show) consists of a preamble followed by a number of slides.
For instance, the pll code
=background_color(0.05,0.05,0.15,1) =slide Welcome! =center Please take a seat =par Coffee is served in the furthest leftmost corner of the room; \ Toilets are located in the corridor to your left. =slide Agenda =item Introduction =item The problem =subitem Setup =subitem Problem Formulation =item Possible Solutions =subitem An Optimal Solution =subitem A Greedy Heuristic =subitem Other heuristics =item Consequences =item Discussion and Wrap Up =begin-par Feel free to interrupt at any time. Post-presentation comments and suggestions mailed to me will be distributed through the mailing-list. =end-par
contains a preamble setting up the background color and two subsequent slides: A welcome-slide and an agenda-slide. This example contains almost all the major pll commands controlling the overall appearance of the content of a slide-show. Thus, it serves as reference for the description below.
