+\section{Introduction}
+
+\LaTeXe{} was released in 1994 and added a number of then-new concepts to
+\LaTeX{}. For package and class authors, these are described in
+\texttt{clsguide-historic}, which has largely remained unchanged. Since then,
+the \LaTeX{} team have worked on a number of ideas, firstly a programming
+language for \LaTeX{} (L3 programming layer) and then a range of tools for
+authors which build on that language. Here, we describe the current, stable set
+of tools provided by the \LaTeX{} kernel for packages and class developers. We
+assume familiarity with general \LaTeX{} usage as a document author, and that
+the material here is read in conjunction with \texttt{usrguide}, which provides
+information for general \LaTeX{} users on up-to-date approaches to creating
+commands, etc.
