mwcls is a set of document classes for LaTeX2e designed with Polish
typographical tradition in mind. Classes include: 'mwart' (which is a
replacement for 'article'), 'mwrep' (replacing 'report'), and 'mwbk' (replacing
'book'). Most features present in standard classes work with mwcls classes.
Some extensions/exceptions include: sectioning commands allow for second
optional argument (it is possible to state different texts for running head and
for TOC), new environments 'itemize*' and 'enumerate*' for lists with long
items, page styles have variants for normal, opening, closing, and blank pages.
