+\section{Introduction}
+
+
+This is a small package for plain Lua\TeX and Lua\LaTeX. In some languages, like
+Czech or Polish, there should be no single letter words at the line
+end, according to the typographical norms. There exists some
+external commands (like \verb!vlna!) or packages (\verb!encxvlna!
+for enc\TeX, \verb!xevlna! for Xe\TeX,
+\verb!impnattypo! for Lua\LaTeX). %This package is for plain
+%lua\TeX and for lua\LaTeX.
+
+Other feature of this package is including of non-breakable space after
+initials, like in personal names, after or before academic degrees
+and between numbers and units (SI and others).
+
+The code is modified version of Patrick Gundlach's answer on
+TeX.sx\footnote{\url{http://tex.stackexchange.com/a/28128/2891}}.
+The difference is that it is possible to specify which single letters
+should be taken into account for different languages.
+The support for degrees and units was added as well.
+% The code works also for single letters at the beginning of the brackets.
+
+
+\section{Usage}
+
+The usage is simple:
+
+\begin{verbatim}
+\input ucode
+\uselanguage{czech}
+%% in the case of luacsplain, use instead:
+%% \chyph
+\input luavlna
+\preventsingledebugon
+\input luaotfload.sty
+\font\hello={name:Linux Libertine O:+rlig;+clig;+liga;+tlig} at 12pt

+\hello
+Příliš žluťoučký kůň úpěl ďábelské ódy.
+Text s krátkými souhláskami a samohláskami i dalšími jevy
+z nabídky možností (v textu možnými).
+
+I začátek odstavce je třeba řešit, i když výskyt zalomení
+není pravděpodobný.

+Co třeba í znaky š diakritikou?

+It is also possible to use the package with Lua\LaTeX, just use
+
+\begin{verbatim}
+ \usepackage{luavlna}
+\end{verbatim}
+
+in the preamble.
+
+\section{Commands}
+
+\begin{mycode}
+\cmd{\singlechars}\marg{language name}\marg{letters}
+\end{mycode}
+
+Enable this feature for certain letters in given language.
+%Language code is internall \TeX\ code for the language, it is $0$ for English,
+%$16$ for Czech. Please note that in \verb|csplain|, language code for Czech
+%is $5$ and you will have to set it yourself.
+
+Default values:
+
+\begin{mycode}
+\begin{verbatim}
+%% only Czech and Slovak are supported out of the box
+\singlechars{czech}{AIiVvOoUuSsZzKk}
+\singlechars{slovak}{AIiVvOoUuSsZzKk}
+\end{verbatim}
+\end{mycode}
+
+%By default, all
+%single letters are processed, this command can be used to pass a
+%string of characters, which should be processed only.
+
+\begin{mycode}
+\cmd{\compoundinitials}\marg{language name}\marg{compounds}
+\end{mycode}
+
+Declare compound letters for given language. Second argument should be comma
+separated list of compound letters, in exact form in which they can appear.
+
+Default values:
+
+\begin{mycode}
+\begin{verbatim}
+\compoundinitials{czech}{Ch,CH}
+\end{verbatim}
+\end{mycode}
+
+\subsection{Turning off language switching}
+
+By default, language of the nodes is taken into account. If you want to use
+settings for one language for a whole document, you can use following command:
+
+\begin{mycode}
+\cmd{\preventsinglelang}\marg{language name}
+\end{mycode}
+
+\subsection{Turning off processing}
+
+If you want to stop processing of the spaces in the document you can use command
+
+\begin{mycode}
+\cmd{\preventsingleoff}
+\end{mycode}
+
+To resume processing, use
+
+\begin{mycode}
+\cmd{\preventsingleon}
+\end{mycode}
+
+You can also disable units and degrees processing:
+
+\begin{mycode}
+ \cmd{\nounits}\\
+ \cmd{\nopredegrees}\\
+ \cmd{\nosufdegrees}
+\end{mycode}
+
+\subsection{Debugging commands}
+\begin{mycode}
+\cmd{\preventsingledebugon}\par
+\cmd{\preventsingledebugoff}
+\end{mycode}
+
+Insert debugging marks on/off. Default off.
+
+\section{Lua module \texttt{luavlna-langno.lua}}
+
+When we process glyph nodes with Lua\TeX\ callbacks, there are \verb|lang|
+fields available. These are numerical codes of languages, but no information
+about language names easily accesible from Lua side is available.\footnote{%
+ Language names are stored in \TeX macros like \verb|\string\l@langname|, but
+ different formats use different naming of these macros}
+These numbers are format dependent, majority of formats like
+Lua\LaTeX use \verb|language.dat| file provided by \verb|babel|
+for assign numbers to languages, but for example \verb|csplain|
+use its own system.
+
+To allow easy setting of language dependent parameters, \verb|langno| module
+was created. It's purpose is to translate language code to language name and
+the other way. Lua\LaTeX, Lua\TeX\ and CSplain formats are supported at the moment.
+
+\subsection{Recognized languages}
+\subsubsection{Lua\TeX\ and Lua\LaTeX}
+
+File \verb|language.dat| is processed to load language names, aliases and assigned numbers. These language names are the same as supported by \verb|babel| package.
+
+\begin{quotation}
+ \small\noindent
+\begin{luacode*}
+ langno = require "luavlna-langno"
+ function print_format_lang(fmt)
+ local luatex = langno.load_languages(fmt)
+ local t = {}
+ for k, v in pairs(luatex.names) do
+ t[#t+1]=k
+ end
+ table.sort(t)
+ tex.print(table.concat(t,", "))
+ end
+ print_format_lang("luatex")
+\end{luacode*}
+\end{quotation}
+
+\subsubsection{CSplain}
+
+Different method is used. File \verb|hyphen.lan| is included in CSplain, where
+language numbers are assigned to ISO-639-1 or ISO-639-2 language codes.
+These language codes were then normalized to names used vy \verb|babel|, or
+standard English language names.
