% This is file ltxtools-incluput.sty, version 0.0.1, December 2011. %
% %
% It can be used to input standalone subsidiary documents without %
% also including their preamble and/or postamble. Files can be %
% 'inputted' or 'included'. %
% %
% If you enter 'persistent=false' in the call to the package, %
% you would have to put \let\documentclass\ltxtools-incluput at the top %
% of every file to be included in the main document, otherwise enter it %
% only in the first file to be input. %
% %
% Use the 'nested' option to input documents that themselves input %
% other documents. %
% %
