1.15.1. General Description

slideshow is a small macro package which simplifies the process of creating slide-show style presentations using plain metapost and ghostscript. The package assists in producing slides with dimensions 6.4 inches wide by 4.8 inches high, which the user is then expected to convert into a pdf file using ghostscript as a PS distiller.
