%% BEGIN seminar.bug
% LAST MODIFIED: December 1997
% The latest version of this file can be obtained from Princeton.EDU.

% This file list some bugs and latebreaking news for seminar.sty,
% version 1.0, released April 1, 1993.

% 1. Typo in the user's guide: \espfslidesize should be \epsfslidesize.

% 2. fancyheadings.sty does not work well with slides.
%    WORKAROUND: Ignore the footnote in the User's Guide that discusses this.
%    Instead:
%
%     - If you want the width of the header to be "\textwidth"
%       (the usual state of affairs), then put
%
%          \renewcommand{\headwidth}{\textwidth}
%
%       in the preamble and do not change "\headwidth" after that.
%
%     - If you want to set the width to something else, then you have to scale
%       it appropriately. E.g., use
%
%          \setslidelength{\headwidth}{<dim>}
%
%       or, if are using the "fancy" page style with both the article and
%       slides formats, use
%          \ifarticle
%            \setartlength{\headwidth}{<dim1>}
%          \else
%            \setslidelength{\headwidth}{<dim2>}
%          \fi

% 3. Some people prefer that the headers/footers automatically adjust their
%    size to the width of the framed slide (I don't, which I guess is why
%    seminar.sty does not work this way.) I have added an option for this.
%    Put the command
%
%      \autoslidemarginstrue
%
%    in the preamble. You must also input this file (seminar.bug), which
%    contains the patch.

% 4. The optional argument in \twoup[int] does not work with the
%    portrait option and slides format.
%    PATCH: Input this file.

% 5. Slide labels can come out in the wrong size font.
%    PATCH: Input this file.

% 6. When \newslide is used inside a list environment, subsequent nested
%    list environments can have the wrong line width.
%    PATCH: Input this file.

% 7. \overlaypagestyle and \layerpagestyle commands ignored.
%    PATCH: Input this file, AFTER inputting semlayer.sty.

% 8. boxedEPS.tex won't work inside slide environments (because seminar.sty
%    erroneously modifies \read so that it is preceded by \immediate).
%    PATCH: Input this file.
