%   SCRIBE.STY -- Make scribe notes
%
%  Francis Bach, 2007; shamelessly taken from Laurent El Ghaoui
%
%   Martin Wainwright;  August, 2004
%
%   Modified from a version by Jeff Erickson (jeffe@cs.uiuc.edu), July 29, 1998
%
%   Loosely based on the MIT/Berkeley scribe notes macros, but
%   written from scratch.
%
% ----------------------------------------------------------------------
%   USAGE:
%
%   \documentstyle[12pt]{report}		NOT article!
%   \usepackage{scribe}
%   ...
%   \begin{document}
%   \course{EECS 227} 				optional
%   \coursetitle{Optimization}	optional
%   \semester{Fall 2004}			optional
%   \lecturer{Jeff Erickson}			optional
%   \scribe{Joe. A Student}			required
%   \lecturenumber{17}				required (must be a number)
%   \lecturedate{October 12}			required (omit year)
%   \maketitle
% ----------------------------------------------------------------------
%   The stuff before \maketitle can be in any order, but it has to go
%   before \maketitle.
%
%   The lecture number appears in all page, section, theorem, figure,
%   table, and equation numbers.  It must be a single positive
%   integer; ranges like 3--5 are not (yet) properly supported.
%
%   Automatically loads the amsmath package, which is a Good Thing,
%   especially if you're going to use a lot of math.  See ``The LaTeX
%   Companion'' for details!
%
%   To get a proof, use \begin{proof}...\end{proof}.  You can attach
%   an optional argument, just as with the standard latex theorem
%   environment.  You can also define new proof-like environments with
%   \newproof{foo}{bar}, just like \newthe\orem.

%  Dangerous bend environments, stolen from TeXbook and slightly
%  massaged.
%
%  Invoke as \begin{[d]danger}...\end{[d]danger}.  The enclosed text
%  is offset just like any other list (theorem, proof, etc.)  Puts
%  sign[s] in front of first two lines of first paragraph, which are
%  (supposedly) never split by a page boundary.  Does NOT shrink or
%  otherwise modify the text.
% ----------------------------------------------------------------------
%  The dangerous bend signs are the correct size to match two lines of
%  Computer Modern 9pt type.   We really ought to scale them up to
%  fit whatever size we're using, but we don't.  Unfortunately, manfnt
%  is actually a 10pt font, so if we want to match 11pt Computer
%  Modern, we have to scale manfnt to 12.222222pt!  Thanks, Don.
