+%
+%    The \texttt{\string\input} is a hack that modifies some values in the
+%    register attribution scheme of $\varepsilon$-\TeX\ and remaps
+%    \texttt{\string\newcount} to \textsf{etex}'s \texttt{\string\globcount}.
+%    We have to do such a remapping in a separate file that Plain doesn't see,
+%    otherwise it outputs an error if we try to change
+%    \texttt{\string\newcount} (because it is an \texttt{\string\outer}
+%    macro). See below for file contents.

+%
+%    This file is very small, it just changes the maximum values of allowed
+%    registers from 32768 to 65536, and remaps \texttt{\string\newcount} (and
+%    friends) to \textsf{etex}'s \texttt{\string\globcount}.
