Please note that this class file requires the Kluwer package for journal submissions, downloadable from www.wkap.nl, `author services', `Journal Stylefiles/Templates'. Also, the attached manual is merely an addendum to usrman.tex, included in the general Kluwer package. You may have trouble compiling usrman.tex. It is probably simpler to use the included PostScript version, usrman.ps, or to download the pdf version. The \documentclass line should specify the class file supplied here, NOT kluwer.cls: you will be using the underlying macros from the Kluwer package, not kluwer.cls itself. Put the .sty, .cl* and .bst files where LaTeX resp. bibtex will find them. The exact location depends on your TeX implementation. Siep Kroonenberg (Siep.Kroonenberg@wkap.nl)
