%% (hopefully) minor changes for \LaTeXe
%% by Peter N"uchter (!PN) peter@mwt.e-technik.uni-ulm.de
%% all changes marked with !PN

%% WARNING: math font problems and workaround:
%%          Standard math commands like 
%%              $\mathbf{N}(0,P(0))$
%%          will not work properly. The reason is, that this is
%%          a simple hack of an old LaTeX2.09 style files.
%%          To get it running, I used the packages
%%              'rawfonts' and 'oldlfont'
%%          They are responsible for the font problems.
%%          This is a known feature, see
%%              http://www.tex.ac.uk/CTAN/latex/bugs.html
%%          
%%      WORKAROUND:
%%      Use an additional pair of braces, like
%%      {\mathbf{y}}
%%      to introduce an additional level of scope.
%%      Examples:
%%              $\mathbf{N}(0,P(0))$ but ${\mathbf{N}}(0,P(0))$
%%              $\mathcal{N}(0,P(0))$ but ${\mathcal{N}}(0,P(0))$
%%              $\mathcal{G}_{t}$ but ${\mathcal{G}}_{t}$
%%              $\mathfrak{G}_t$ but ${\mathfrak{G}}_t$
%%
%%
%% Changes: 10.01.1996
%%      \@maxsep removed
%%      \@dblmaxsep removed
%%      \typeout{Upgraded to `IEEEtran.cls' <10-Jan.-1996>.} added
%%      \usepackage{rawfonts} added
%%      \usepackage{oldlfont} added
%%      \renewcommand{\normalsize}{\fontsize{10}{12}\selectfont} added
%%      \AtBeginDocument{\parindent1.0em} added
%%
%% Changes: 14.05.1996
%%      \setlength - bock added.
%%      \renewcommand{\normalsize}{... hopefully fixed!
%%      \topsep defs inserted at pointsize declarations
%%         ^^-- this is a little bit tricky. I fiddled around until
%%              I nearly obtained the same result as with LaTeX209.
%%              I think we can live with that now?
%%
%% Changes: 1.5.1997
%%      Inclusion of math-font-problem-section on top of this file!
%%
%%
%% Resulting Differenzes between \LaTeX209 and \LaTeX:
%%      Slightly different formatting.
