Elpres is a simple class for presentations to be shown on screen or
beamer. It is derived from LATEX's article class. Elpres
is primarily intended to be used with PDFLATEX or with LATEX,
dvips and Ghostview/Ghostscript. The default "virtual paper size"
of documents produced by this class: width=128mm, height=96mm corresponds to a
4:3 aspect ratio. Other aspect ratios for widescreen monitors may be selected
by class options. Elpres requires that the ifthen,
fancyhdr and geometry packages are available on the system.
Enhancements to elpres are easily made available by other packages,
these include overlay support for incremental slides (package
overlays) hypertext elements (hyperref package) and slides
with a background from a bitmap (wallpaper, eso-pic
