"In order to minimize the generation of bitmaps and to allow the production of a better quality HTML source, the information in the LaTeX source was tagged by LaTeX macros to explicitly show its semantics meaning. Special care was taken to avoid inline mathematics constructs, since they result in bitmap images, for example, \var{x} was preferred to its typographic equivalent $x$ (denoting a meta-variable), and \nth{v}{n} was used to mean the n-th component of v, rather than writing $v_n$. The same technique was also used to eliminate "low-level'' typesetting constructs and environments such as center and tabular."
