+     "This is a complete and easy-to-use package for typesetting pretty tables of
+signs and variations according to French usage.  The syntax is similar to that
+of the @code{array} environment and uses intuitive position commands.  Arrows
+are drawn automatically (using PSTricks by default or TikZ as an option).
+Macros are provided for drawing twin bars, single bars crossing the zeros,
+areas where the function is not defined, or placing special values.  Several
+features of the variation tables can be customized.")
