% Author: Stephan Lehmke <Stephan.Lehmke@cs.uni-dortmund.de>
%
% v0.0.1 Mar 28, 2000 First version for the pre-alpha release of texpower and hyperref v6.70a.
%
% v0.0.1a May 18, 2000 Added a \vss to a \vbox to get rid of an `overfull vbox' message.
%
% v0.0.2 Jun 02, 2000 Now handle seminar as well as powersem.
%
% v0.0.3 Sep 07, 2000 hyperref v6.70u and later don't have the \@hyperfixhead bug any more.
%
% v0.0.4 Nov 22, 2002 Now using ifpdf package if available.
% As hyperref v6.70u exists for some time now, the \@hyperfixhead hack is removed.
% Fixed a problem with \twoup (bug found and fix proposed by Laurent Mugnier).
% Added a preliminary fix for rotating slides with pdftex.
%
% v0.0.5 May 26, 2003 A small change to make fixseminar work better when hyperref is not loaded.
