The beamer LaTeX class can be used for producing slides. Its functionality is similar to Prosper but does not need any external programs and can directly produce a presentation using pdflatex. Beamer uses pgf for pdf/ps independent graphics. Frames are created using \frame{...}, and a frame can build multiple slides through a simple notation for specifying material for each slide within a frame. Beamer supports bibliographies, appendicies and transitions. Short versions of title, authors, institute can also be specified as optional parameters. A \plainframe{} allows a picture, for example, to fill the whole frame. Support figure and table environments, transparency effects, a \transduration command, animation commands, a pauses environment. Beamer also provides compatibility with other packages like prosper .
