hyphenation patterns in the 8-bit encoding of the font in use (such encodings
are codified in the LaTeX scheme with names like OT1, T2A, TS1, OML, LY1,
etc).  The present package offers a collection of conversions of existing
patterns to UTF-8 format, together with converters for use with 8-bit fonts in
older systems.  Since hyphenation patterns for Knuthian-style TeX systems are
only read at iniTeX time, it is hoped that the UTF-8 patterns, with their
converters, will completely supplant the older patterns.")

compilation of LaTeX documents.  This includes compiling the document itself,
of course, enough times so that all references are defined, and running BibTeX
to manage bibliographic references.  Automatic execution of dvips to produce
PostScript documents is also included, as well as usage of pdfLaTeX to produce
PDF documents.")
