\nameoffile{\tkznameofpack}
\defoffile{\textbf{tkz-tab.sty} is a package for drawing tables of signs and tables of variations with \TIKZ, as simply as possible. These tables are the usual way, in French secondary schools and universities, to summarize the study of a function: the sign of its derivative and its increasing or decreasing intervals, with its limits and extreme values. The package depends on \TIKZ\ and belongs to a series of packages whose common aim is to create drawings that are useful for teaching mathematics. I hope that reading this documentation will help you appreciate how easy \TIKZ\ is to use, and will encourage you to start using it.}
