+and yet still looking rather nicely in a way that separates content from
+presentation and with re-usable layout for tables of the same type.  For this
+purpose, the package provides the environment @code{KeyValTable}, which allows
+one to typeset tables that have a previously defined column layout and whose
+rows can be produced in a key-value fashion.")
