Revtex is an electronic publishing product of the american physical society. it is a set of latex-based tags that can be used to prepare a physics manuscript for submission. if revtex tags are used consistently throughout a manuscript and published guidelines are followed exactly, it is hoped that the tex manuscript file (called a compuscript) can be used by aps, osa, aip, and other participating member societies in production of author proofs. this package is now obsolete, revtex 4, provided by the package tetex-extra should be used instead. this package is kept in order to provide backward compatibility (for older documents prepared with revtex 3.1 rather than revtex 4).
