% \begin{abstract}
% This convenience package loads all of the (stable) packages in the
% \pk{luatexbase} bundle.
% \end{abstract}

%
% \section{Documentation}
%
% The \pk{luatexbase} package loads the following packages:
% \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}
%
% These packages are almost stable: it is unlikely that backward-incompatible
% changes will be made in the future (other than necessary for merging with
% \pk{luatex.sty}, which strongly overlaps with the above). If they happen,
% such changes will be announced on \email{lualatex-dev@tug.org} before they
% are pushed to the master branch and then CTAN.
%
% Other packages included in the bundle, but currently not loaded by the
% present package, are:
% \begin{description}
%   \subpk{modutils} Lua module declaration, including version checks.
%   \subpk{mcb} callbacks extensions allowing to register many functions in a
%   single callback, and declare new callbacks for packages.
% \end{description}
%
% All packages in this bundle are supposed to work with \luatex 0.25.4 to
% 0.60.x, with formats based on \plaintex or \latex, as included in \texlive
% 2008, 2009, and 2010.
