% \begin{abstract}
% This package provides resource management for the LuaTeX macro programmer.
%
% It is now a wrapper around \pk{luatexbase} subpackages, with additinal names
% for some macros in order to ensure compatibility with previous versions of
% this package. You are encouraged to use \pk{luatexbase} directly and switch
% to the new names.
% \end{abstract}

%
% \section{Documentation}
%
% The \pk{luatex} package loads the following sub-packages of \pk{luatexbase}:
% \begin{description}
%   \subpk{compat} compatibility helpers for \verb+\directlua+, primitive
%   names and version information from Lua.
%   \subpk{loader} extension of \luatex's Lua module loader (since version
%   0.60.0, this is more of a compatibility layer for older versions than a
%   real extension).
%   \subpk{regs} extented allocation scheme for registers and the like,
%   \emph{\`a la} \pk{etex}.
%   \subpk{cctb} catcode table allocation.
%   \subpk{attr} attribute allocation.
% \end{description}
%
% In addition, it defines the following synonyms:
% \begin{center}
% \begin{tabular}{rl}
% \toprule
% Deprecated name & New name \\
% \midrule
% \cs{newattribute} & \cs{newluatexattribute} \\
% \cs{setattribute} & \cs{setluatexattribute} \\
% \cs{unsetattribute} & \cs{unsetluatexattribute} \\
% \cs{newcatcodetable} & \cs{newluatexcatcodetable} \\
% \bottomrule
% \end{tabular}
% \end{center}
% The deprecated names trigger a warning and will be removed in a future
% version.
