%% This is the LaTeX package dblfloatfix which solves two problems:
%% a)~floats in a twocolumn document come out in the right order and
%% b)~allowed float positions are now [tbp].
%%
%% It may be distributed and/or modified under the
%% conditions of the LaTeX Project Public License, either version 1.3c
%% of this license or (at your option) any later version.
%% The latest version of this license is in
%% http://www.latex-project.org/lppl.txt
\ProvidesPackage{dblfloatfix}[2012/12/31 v1.0a (JAW)]
%%
%% USAGE:
%%
%% This package redefines internals of the LaTeX kernel by merging
%% the code of the packages fixltx2e (the fix2col part) and stfloats.
%%
%% If either of the packages stfloats or fix2col are loaded you will
%% get an error message and your document will probably not be able
%% to compile. So don't load them!
%%
%% When the new output routine for LaTeX3 is done, this package will
%% be obsolete. The sooner the better...
%%
%% If you're using the subfigure package this package will provide a
%% fix for \end@dblfloat by Steven Cochran (the author of subfigure).
%%
%% Morten H\o gholm, <moho0...@student.cbs.dk>
\RequirePackage{fixltx2e}
%% An error message for those who didn't read the instructions.

\PackageError{dblfloatfix}{%
Don't use the #1 package!^^J%
Didn't you read the instructions in dblfloatfix.sty?!^^J%
You're in big trouble now...^^J%
Quit immediately (type `X') and correct the mistake}%
{Type `X' dammit!}%
