\nameoffile{\tkznameofpack}

\defoffile{\textbf{tkz-fn.sty (v\tkzversionofpack)} is a package for drawing graphs of functions in 2D as simply as possible, with \TIKZ\ and Lua. It is the successor of \tkzname{tkz-fct}: \tkzname{gnuplot}, \tkzname{fp.sty} and \tkzname{tkz-base} are no longer needed, every computation is done by Lua and the document is compiled with \tkzname{LuaLaTeX}. The drawings are the kind used in high school mathematics; the presentation (French or American conventions, ``box'' axes as with \tkzname{pgfplots}) is chosen with options.}

\vspace*{24pt}
\noindent\lefthand\ I would like to thank \tkzimp{Till Tantau} for the wonderful tool \tkzname{\TIKZ}, and \tkzimp{Michel Bovani} for the \tkzname{fourier} fonts.

\vspace*{12pt}
\noindent\lefthand\ I would also like to thank \tkzimp{David Arnold}, \tkzimp{Pablo González Luengo}, \tkzimp{Wolfgang Büchel}, \tkzimp{John Kitzmiller} and \tkzimp{Gaétan Marris} for their help with \tkzname{tkz-fct}; the examples of this documentation come from it.
