% \section{Setting up the \LaTeX3 programming language}
%
% This module is at the core of the \LaTeX3 programming language. It
% performs the following tasks:
% \begin{itemize}
%   \item defines new names for all \TeX{} primitives;
%   \item emulate required primitives not provided by default in \LuaTeX;
%   \item switches to the category code r{\'e}gime for programming;
% \end{itemize}
%
% This module is entirely dedicated to primitives (and emulations of
% these), which should not be used directly within \LaTeX3 code
% (outside of \enquote{kernel-level} code). As such, the primitives
% are not documented here: \emph{The \TeX{}book}, \emph{\TeX{} by
% Topic} and the manuals for \pdfTeX{}, \XeTeX{}, \LuaTeX{}, \pTeX{}
% and \upTeX{} should be consulted for details of the primitives.
% These are named \cs[no-index]{tex_\meta{name}:D}, typically based
% on the primitive's \meta{name} in \pdfTeX{} and omitting a leading
% |pdf| when the primitive is not related to pdf output.
%
% \end{documentation}

%
% \section{\pkg{l3names} implementation}
%
%    \begin{macrocode}
%<*package&tex>
%    \end{macrocode}
%
% The prefix here is \texttt{kernel}.  A few places need |@@| to be left
% as is; this is obtained as |@@@@|.
%    \begin{macrocode}
%<@@=kernel>
%    \end{macrocode}
%
% The code here simply renames all of the primitives to new, internal,
% names.
%
% The \tn{let} primitive is renamed by hand first as it is essential for
% the entire process to follow. This also uses \tn{global}, as that way
% we avoid leaving an unneeded csname in the hash table.
%    \begin{macrocode}
\let \tex_global:D \global
\let \tex_let:D    \let
%    \end{macrocode}
%
% Everything is inside a (rather long) group, which keeps
% \cs{@@_primitive:NN} trapped.
%    \begin{macrocode}
\begingroup
%    \end{macrocode}
%
% \begin{macro}{\@@_primitive:NN}
%   A temporary function to actually do the renaming.
%    \begin{macrocode}
  \long \def \@@_primitive:NN #1#2
    { \tex_global:D \tex_let:D #2 #1 }
%    \end{macrocode}
%\end{macro}
%
% To allow extracting \enquote{just the names}, a bit of DocStrip fiddling.

%    \end{macrocode}
%
% In the current incarnation of this package, all \TeX{} primitives
% are given a new name of the form |\tex_|\emph{oldname}|:D|.
% But first three special cases which have symbolic original names.
% These are given modified new names, so that they may be entered
% without catcode tricks.

% renamed with \LuaTeX{} having a lot more. These names now all start
