% 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.                                                         %
%                                                                          %
