+supports: hyphenation of words for 50+ languages, simple and powerful font
+loading system (various sizes of fonts), TeX, pdfTeX, XeTeX and LuaTeX
+engines, math fonts simply loaded with full amstex-like features, three
+internal encodings (IL2 for Czech/Slovak languages, T1 for many languages with
+latin alphabet and Unicode in new TeX engines), natural UTF-8 input in pdfTeX
+using encTeX without any active characters, Czech and Slovak special
+typesetting features.  An important part of the package is OPmac, which
+implements most of LaTeX's features (sectioning, font selection, color, hyper
+reference and URLs, bibliography, index, table of contents, tables, etc.) by
+Plain TeX macros.  The OPmac macros can generate a bibliography without any
+external program.")
