+     "The @code{rtkinenc} package is functionally similar to the standard LaTeX
+package @code{inputenc}: both set up active characters so that an input
+character outside the range of 7-bit visible ASCII is converted into one or
+more corresponding LaTeX commands.  The main difference lies in that
+@code{rtkinenc} allows the user to specify a fallback procedure to use when
+the text command corresponding to some input character isn't available.  Names
+of commands in @code{rtkinenc} have been selected so that it can read
+@code{inputenc} encoding definition files, and the aim is that @code{rtkinenc}
+should be backwards compatible with @code{inputenc}.  @code{rtkinenc} is not
+a new version of @code{inputenc} though, nor is it part of standard LaTeX.")
