% Written by Nick Urbanik, 14-10-94

% Latest requirements by Dennis for his newer (probably not newest)
% lab sheet format:
% Put a Huge version box at the bottom of the front page.
% Leave a large empty space above this (poor trees!)
% Remove the subject name (this is sensible from the production point
% of view, but less so from the student's and lab manager's point of
% view).  Perhaps put the subject number in tiny writing under the
% revision number.
% Remove the lab sheet number (similar to above).
% There are three parts: A. Background, B. Procedure C. Discussion.
% Each part has a big font, bold header in small caps.
% Other headings are bold italic, 12pt, with a small space before the
% text.
% Headings outside of part B are not numbered.
% Headings in part B are numbered; these numbers are not bold.
% Each step of the procedure is numbered under the numbering of the
% header.
% Wherever the student needs to write or draw something, a symbol is
% shown at the margin on the left.
% Headers and footers are quite changed:
% the header has a rule, above which is the name of the College in bold
% capitals, about 10pt. 
% The footer has EE Department on the left, Page Xn, where X is A, B
% or C, and n is the pagenumber within that part, in the centre of the
% footer, and on the right is the Departmental reference number.
% These are all in bold 10pt.  I propose to add the subject code in
% tiny font under the reference number.
% Use boxes for the student to put drawings in.
% OTHER CHANGES:
% I need to change the result.sty command: the lines need to be
% indented.  Perhaps write a new style file for this.
% I need to change my numbers to being not bold.

% NOTE: the department requires a reference number for each lab sheet.
% They have been allocated by Angela as 15 codes:
%
% EE/27/LA/06/95
% EE/27/LA/07/95
% EE/27/LA/07/95
%           .
%           .
% EE/27/LA/21/95
% The first is the department; the second is the subject code; the 3rd means
% lab; the fourth is the lab number; the last is the year.

% Also, a revision box is needed at the end of each lab sheet, with the
% headings Compiled by, Issue, Date, Remark.
% Here is the one from workshop 1:
% \vfill
% 
% \begin{center}
% \tiny
% \begin{tabular}{|l|c|c|p{4cm}|}
% \hline
% \multicolumn{1}{|c|}{Compiled by} & Issue & Date &
% \multicolumn{1}{c|}{Remark} \\
% \hline
% Nick Urbanik & 1 & 4-10-95 & This is a totally new lab, written
% from scratch.  It is suitable as an introduction for all
% microprocessor courses, though it is initially targetted at a 2 hour
% workshop. \\

% $Log: lab.cls $
% Revision 1.13  2000/03/24 01:38:42  nicku
% Added support for using the Solutions environment that is activated when
% select the solutions option.
%
% Revision 1.12  1999/10/19 02:37:06  nicku
% Updated to IVE, IVE logo.
% Got rid of the silly Departmental page numbering system.
%
% Revision 1.10  1998/04/20 02:19:20  Nick
% 1. Made the section headings more compact.
% 2. Updated the revision number ot 1998.
%
% Revision 1.9  1998/01/12 02:27:58  Nick
% Removed many comments.
% Minor changes.
%
% Revision 1.8  1997/09/04 04:03:53  Nick
% This version was made last year.
% I think the aim was to use the postscript logo, and to make it
% work with the labs I wrote last year.
% Now Dennis has given us yet _another_ format for the lab sheets.
% So to change it yet _again_.
%
% Revision 1.7  1996/11/11 10:06:38  Nick
% Have added support for solutions.
% Have also used the resultan.sty package instead of result.sty.
% This introduces compatibility problems that require change in the source
% before a lab can be compiled.  I hope that this is not a mistake!
%
% Revision 1.6  1996/10/23 15:32:13  Nick
% Major revisions.
% Have added embedded and other options.
% Used to print up to 23-10-96
%
% Revision 1.5  1996/10/14 03:14:59  Nick
% This is the work I did on lab.cls in the microprocessor lab.
%
% Revision 1.4  1996/10/03 19:42:46  Nick
% This is a major revision: it now works with the "correct" Departmental
% logo style.
% There is minor cheating: the subject is shown in small letters
% to avoid the massive confusion that would otherwise result.
%
% Revision 1.3  1996/10/03 01:00:46  Nick
% Huge changes since last check in at home.
%
% Revision 1.1  1996/01/03  13:06:09  Nick
% Initial revision
%
% Revision 1.9  1995/02/19 12:45:35  Nick
% Major revision.
% Changed the headers and footers.
% Added revision control support for printing version numbers in lab sheets.
%
% Revision 1.8  1994/11/05  18:50:42  Nick
% Fixed missing comments.
% Moved \eemph into nick.sty.
% Fixed the overful box warning that got each page with fancyheadings
% Added Group field on front of lab sheet.
%
% Revision 1.7  1994/10/23  21:59:43  Nick
% Added varioref to list of packages used (it's indespensible!).
% Also fixed definition of eemph.
%
% Revision 1.6  1994/10/22  17:40:27  Nick
% 1. Have added an example of use of this class.
% 2. Have added some shorthand commands.
%
% Revision 1.5  1994/10/22  16:34:17  Nick
% Have added a subject number, and the mechEng option.

% Latest change, 19-4-96: Have added the support for float pages to be
% without the right mark, as explained in fancyheadings.tex.  Have
% also ensured that ``References'' doesn't come out in capitals.
