+     "This package is designed for typesetting the programmable elements in digital
+hardware, i.e., registers.  Such registers typically have many fields and can
+be quite wide; they are thus a challenge to typeset in a consistent manner.
+Register is similar in some aspects to the @code{bytefield} and
+@code{bitpattern} packages.  Anyone doing hardware documentation using LaTeX
+should examine those packages.  An example Perl module and script are
+provided, to convert the register specifications into structures suitable for,
+say, a pre-silicon test environment.")
