{Creating magical \PDF\ documents with pdf\TeX}
{Rishi}
{\PDF{} has a rich specification. But Adobe Distiller does not exploit all
these specifications. We'll demonstrate how pdf\TeX\ can create useful
\PDF{} files that are difficult or impossible to create using other
technologies. Examples are: \PDF{}s showing differences in two \TeX\ source
files; \PDF{}s with useful pop-up tools; and a simple but useful
composite \PDF{} for comparing two nearly identical \PDF{} files.}
