%%
%%
%% The file modifies the tabularx environment to
%% combine the features of the tabularx package
%% (auto-sized columns in a fixed width table) 
%% with those of the longtable package 
%% (multi-page tables).
%% 
%% The tables are typeset using the tabularx environment
%% and the longtable environment is used internally to
%% handle multi-page tables. The \setlongtables feature
%% is used, and, therefore, the document should be
%% run through latex twice.
%% 
%% Another feature that has been added is to treat the X 
%% columns like 'l' columns if the table contents would allow
%% that to happen without exceeding the specified width of
%% the table. In other words, the specified width is 
%% treated as the maximum allowed and not the exact width 
%% of the table. This feature is the default but can be 
%% disabled (or enabled) with \keepXColumns (or \convertXColumns).
%%
%% Caveats:
%%   . The document needs to be latexed a couple times in general.
%%   . In general, it is necessary to remove the .aux file before
%%     the first latex run on the document.
%%   . The table should not be larger than TeX's memory capacity
%%
%%
%% Here is a a simple usage example:
%%
%%
%% \documentclass{article}
%% 
%% \usepackage{ltablex}
%% 
%% \textheight=4in
%% 
%% \begin{document}
%% 
%% % we want a table that is \textwidth long, has 4 columns, columns 1
%% % and 3 are auto sized with the 3rd columns being 3 times wider than
%% % the first column.
%% %
%% 
%% 
%% \begin{tabularx}{\linewidth}%
%%  {|>{\setlength{\hsize}{.5\hsize}\raggedright\arraybackslash}X| % col 1; auto-sized ragged right
%%     c|                                                        % col 2; default    centered
%%     >{\setlength{\hsize}{1.5\hsize}\raggedleft\arraybackslash}X|% col 3; auto-sized ragged left
%%     l|}                                                       % col 4; default    left-justified
