Tools to typeset monolingual Polish documents in LaTeX2e without babel or polyglossia. The package loads Polish hyphenation patterns, ensures that a font encoding suitable for Polish is used; in particular it enables Polish adaptation of Computer Modern fonts (the so-called PL fonts), provides translations of \today and names like "Bibliography" or "Chapter", redefines math symbols according to Polish typographical tradition, provides macros for dashes according to Polish orthography, provides a historical input method for "Polish characters", works with traditional TeX as well as with Unicode aware variants. (This package was previously known as platex, but has been renamed to resolve a name clash.)
