3. Controlling Appearance

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.
