+exam-n: LaTeX class file for exams, version 1.1, 2014 May 03.
+[ Mercurial revision 6f818b549982, 2014-05-03 13:42 +0100, tag 1.1 + 0 ]
+
+
+Overview
+--------
+
+The class is designed to be localised to a particular institution's
+exam layout, by a suitably skilled LaTeX hacker. There are three
+possible ways of doing this, in increasing order of sophistication:
+
+ 1. Make suitable adjustments to individual exam `.tex` files.
+
+ 2. Rename the distributed `exam-n.dtx` file to something more locally
+ suitable, and edit it with suitable changes (search for
+ `%%%CONFIGURE` for hints on where to adjust).
+
+ 3. Fork the Mercurial repository at
+ [bitbucket](https://bitbucket.org/nxg/exam-n), change the
+ value of the `EXAM-N` variable in the `Makefile`, and then
+ edit the `exam-n.dtx` file. See the comments at the top of the
+ `Makefile`. The command `make dist` will assemble a tarball
+ release of the class file.
+
+In the last two cases, if you change the `.dtx` file, you _must_ also
+change its name, to avoid confusion.
+
+For general details, talk to Norman Gray <norman@astro.gla.ac.uk>.
+
+This is free software, and you are encouraged to use and adapt it as
+you see fit. If, however, you need more substantial help with the
+customisations of option 3 above, or need continuing support, then
+[Norman can help](http://8ameter.com), on a commercial basis.
+
+With the version 1.1 release, the interface should now be regarded
+as rather stable. However version 1.1 was the first to be released
+outside Glasgow University, so there may be some changes to the
+interface which will emerge with broader use, as well as some bug
+fixes. The interface _may_, therefore, yet change. If you use
+this class to produce exams, it would be wise to include a copy of
+the class file locally, rather than relying on a central version. If
+you need an earlier version of the class, let me know.
+
+
+Documentation
+------------
+
+ * Documentation for question authors is in `notes-for-authors.pdf`.
+ * The full version of the documentation, for 'exam conveners' (or
+ equivalent) is in `exam-n.pdf`. This and the author
+ documentation are built as part of the distribution.
+ * Basic documentation for a LaTeX localiser is in this file (see
+ above), with extra remarks at the top of the `Makefile`.
+
+There are brief release notes in exam-n.html.

+\begin{document}
+\maketitle
+
+\section{I}
+
+\begin{question}{20}
+\part At various points in the development of the mathematical theory of
+General Relativity, we pick a coordinate system in which
+differentiation is simple, and do a calculation using non-covariant
+differentiation, indicated by a comma. We then immediately deduce the
+covariant result, replacing this comma with a semicolon.
+
+Separately, the strong equivalence principle is sometimes
+referred to as the `comma goes to semicolon' rule.
+
+Explain the logic of each of these replacements of a comma with a
+semicolon, putting particular stress on the distinction between
+them.\partmarks{10}
+
+\part The radial and angular coordinates, $r$ and $\phi$ respectively,
+of a test particle moving in the Schwartzschild metric exterior to a
+star of mass $M\ll r$, are related by the equation
+\[
+ r = \frac{h^2}M \left(
+ 1 + e\cos\phi + \frac{3M^2}{h^2}e\phi\sin\phi
+ \right)^{-1},
+\]
+where $h$ and $e$ are constants. Show that this equation takes the
+form of a precessing ellipse, of semi-latus rectum $l=h^2/M$, in which
+the pericentre line advances each orbit by an amount
+$\Delta=6\pi M^2/h^2$, stating clearly any assumptions that
+you make.\partmarks{6}
+
+The solar-mass star HD83443 has a 0.35 Jupiter-mass planet that
+follows a circular orbit of period 2.986 days and radius 0.038\units\au.
+Calculate the rate of precession, in arcseconds per year, of the
+pericentre line of the planet's orbit.\partmarks{4}
+
+[Schwartzschild radius of the Sun${}= 3.0\times10^3\units{m}$,
+$1\units\au=1.5\times10^{11}\units m$].
+
+\begin{solution}
+ In the first type of calculation, we do a calculation in the LIF, in
+which~$\Gamma^i_{jk}=0$, so that single partial differentiation is the
+same as covariant differentiation. If this process produces a
+geometrical object such as a scalar or a tensor, then we know that the
+result is frame-invariant. If the result involves only single partial
+differentiation -- that is, no second derivatives -- then since
+partial differentiation is the same as covariant differentiation in
+these coordinates, we cannot distinguish partial and covariant
+derivatives, and can replace the commas by semicolons. Since these
+are now manifestly covariant derivatives, so that the result is a
+tensor, and thus frame-invariant, the same expression would be true in
+any frame.
+
+The second situation is the statement that the expressions of physical
+laws in SR, such as the conservation equation
+$T^{\mu\nu}_{,\nu}=0$, must take the same \emph{form} when written
+as a covariant equation in GR, crucially without any curvature
+coupling. The slogan `comma goes to semicolon' is just a mnemonic for
+this.
+
+The distinction is that the first is a mathematical trick, of sorts,
+whereas the second is a version of the equivalence principle, and thus
+a statement with deep physical content.
+
+They don't have to explain things at this length or with this
+coherence (?) to get quite a few marks. They just have to show they
+have a clue.

+
+<h2>Overview</h2>
+
+<h3>Other exam styles</h3>
+<p>There are already multiple ‘exam’ LaTeX styles on CTAN,
+including
+the (original?) <a href='http://dante.ctan.org/tex-archive/macros/latex/contrib/exam/'>exam class</a>,
+the extensive <a href='http://www.math.uakron.edu/~dpstory/webeq.html' >AcroTeX</a> bundle,
+the
+<a href='http://dante.ctan.org/tex-archive/macros/latex/contrib/examdesign/'>examdesign</a> and
+<a href='http://dante.ctan.org/tex-archive/macros/latex/contrib/exams/'>exams</a>
+classes, and
+<a href='http://www.tex.ac.uk/cgi-bin/CTANcataloguesearch.pl?CATSTRING=exam'>a variety of other packages</a>
+which mention exams in some way.
+Some of these are more focused on generating quizzes
+(even doing things like randomising answers)
+or on having a highly customisable layout.
+Several (including ‘exam-n’) have support for generating versions of
+the exam document which include answers, for the benefit of
+markers.</p>
+
+<h3>The exam-n style</h3>
+<p>What the ‘exam-n’ class can bring to this particular (rather crowded)
+party is:</p>
+<ul>
+<li>Direct support for collaborative development of an exam, using a
+model in which a departmental ‘exams convener’ or ‘exam chair’
+coordinates multiple authors writing individual questions. This
+includes various completeness checks to avoid embarrasing mistakes.
+The class file and associated process is in regular use within a
+physics and astronomy department, and this work-flow is discussed in a
+little more detail within the class file documentation.</li>
+<li>Designed to have all of the ‘traditional’ exam paper features such
+as sectioning, per-part running marks, ‘Question <em>n</em> continued’
+catchwords, and so on.</li>
+<li>Designed to be locally adaptable.</li>
+<li>The class file is freely adaptable (LPPL), but the author is
+available for <a href='http://8ameter.com'>paid support</a> if that is
+useful.</li>
+</ul>
+
+<p>The focus of the ‘exam-n’ class is on the careful collaborative
+process of assembling an exam, and many of the features are to do with
+checks to avoid mistakes. The result has, in effect, been validated
+by practice.</p>
+
+<h2>To install</h2>
+<p>Unpack the distribution tarball or zip
+file, and move the directory <code>move-to-texmf</code> to some
+location on the LaTeX search path. You're probably looking for a
+directory called <code>texmf-local</code>, or something like that.</p>
+
+<h2>Releases</h2>
+
+<p>With the version 1.1 release, the interface should now be regarded
+as rather stable. However version 1.1 was the first to be released
+outside Glasgow University, so there may be some changes to the
+interface which will emerge with broader use, as well as some bug
+fixes. The interface <em>may</em>, therefore, yet change. If you use
+this class to produce exams, you should therefore include a copy of
+the class file locally, rather than relying on a central version. If
+you need an earlier version of the class, let me know.</p>
+
+<p>The class was called <code>exam</code> until release 0.14, and
+<code>guexam</code> until release 1.1. In the first case, it was
+renamed to avoid a conflict with a pre-existing LaTeX class with the
+same name; and in the second it was renamed to make it more
+generically useful to other institutions.</p>

+
+
+PREAMBLE
+========
+
+The LaTeX Project Public License (LPPL) is the primary license under
+which the LaTeX kernel and the base LaTeX packages are distributed.
+
+You may use this license for any work of which you hold the copyright
+and which you wish to distribute. This license may be particularly
+suitable if your work is TeX-related (such as a LaTeX package), but
+it is written in such a way that you can use it even if your work is
+unrelated to TeX.
+
+The section `WHETHER AND HOW TO DISTRIBUTE WORKS UNDER THIS LICENSE',
+below, gives instructions, examples, and recommendations for authors
+who are considering distributing their works under this license.
+
+This license gives conditions under which a work may be distributed
+and modified, as well as conditions under which modified versions of
+that work may be distributed.
+
+We, the LaTeX3 Project, believe that the conditions below give you
+the freedom to make and distribute modified versions of your work
+that conform with whatever technical specifications you wish while
+maintaining the availability, integrity, and reliability of
+that work. If you do not see how to achieve your goal while
+meeting these conditions, then read the document `cfgguide.tex'
+and `modguide.tex' in the base LaTeX distribution for suggestions.
+
+
+DEFINITIONS
+===========
+
+In this license document the following terms are used:
+
+ `Work'
+ Any work being distributed under this License.
+
+ `Derived Work'
+ Any work that under any applicable law is derived from the Work.
+
+ `Modification'
+ Any procedure that produces a Derived Work under any applicable
+ law -- for example, the production of a file containing an
+ original file associated with the Work or a significant portion of
+ such a file, either verbatim or with modifications and/or
+ translated into another language.
+
+ `Modify'
+ To apply any procedure that produces a Derived Work under any
+ applicable law.
+
+ `Distribution'
+ Making copies of the Work available from one person to another, in
+ whole or in part. Distribution includes (but is not limited to)
+ making any electronic components of the Work accessible by
+ file transfer protocols such as FTP or HTTP or by shared file
+ systems such as Sun's Network File System (NFS).
+
+ `Compiled Work'
+ A version of the Work that has been processed into a form where it
+ is directly usable on a computer system. This processing may
+ include using installation facilities provided by the Work,
+ transformations of the Work, copying of components of the Work, or
+ other activities. Note that modification of any installation
+ facilities provided by the Work constitutes modification of the Work.
+
+ `Current Maintainer'
+ A person or persons nominated as such within the Work. If there is
+ no such explicit nomination then it is the `Copyright Holder' under
+ any applicable law.
+
+ `Base Interpreter'
+ A program or process that is normally needed for running or
+ interpreting a part or the whole of the Work.
+
+ A Base Interpreter may depend on external components but these
+ are not considered part of the Base Interpreter provided that each
+ external component clearly identifies itself whenever it is used
+ interactively. Unless explicitly specified when applying the
+ license to the Work, the only applicable Base Interpreter is a
+ `LaTeX-Format' or in the case of files belonging to the
+ `LaTeX-format' a program implementing the `TeX language'.
+
+
+
+CONDITIONS ON DISTRIBUTION AND MODIFICATION
+===========================================
+
+1. Activities other than distribution and/or modification of the Work
+are not covered by this license; they are outside its scope. In
+particular, the act of running the Work is not restricted and no
+requirements are made concerning any offers of support for the Work.
+
+2. You may distribute a complete, unmodified copy of the Work as you
+received it. Distribution of only part of the Work is considered
+modification of the Work, and no right to distribute such a Derived
+Work may be assumed under the terms of this clause.
+
+3. You may distribute a Compiled Work that has been generated from a
+complete, unmodified copy of the Work as distributed under Clause 2
+above, as long as that Compiled Work is distributed in such a way that
+the recipients may install the Compiled Work on their system exactly
+as it would have been installed if they generated a Compiled Work
+directly from the Work.
+
+4. If you are the Current Maintainer of the Work, you may, without
+restriction, modify the Work, thus creating a Derived Work. You may
+also distribute the Derived Work without restriction, including
+Compiled Works generated from the Derived Work. Derived Works
+distributed in this manner by the Current Maintainer are considered to
+be updated versions of the Work.
+
+5. If you are not the Current Maintainer of the Work, you may modify
+your copy of the Work, thus creating a Derived Work based on the Work,
+and compile this Derived Work, thus creating a Compiled Work based on
+the Derived Work.
+
+6. If you are not the Current Maintainer of the Work, you may
+distribute a Derived Work provided the following conditions are met
+for every component of the Work unless that component clearly states
+in the copyright notice that it is exempt from that condition. Only
+the Current Maintainer is allowed to add such statements of exemption
+to a component of the Work.
+
+ a. If a component of this Derived Work can be a direct replacement
+ for a component of the Work when that component is used with the
+ Base Interpreter, then, wherever this component of the Work
+ identifies itself to the user when used interactively with that
+ Base Interpreter, the replacement component of this Derived Work
+ clearly and unambiguously identifies itself as a modified version
+ of this component to the user when used interactively with that
+ Base Interpreter.
+
+ b. Every component of the Derived Work contains prominent notices
+ detailing the nature of the changes to that component, or a
+ prominent reference to another file that is distributed as part
+ of the Derived Work and that contains a complete and accurate log
+ of the changes.
+
+ c. No information in the Derived Work implies that any persons,
+ including (but not limited to) the authors of the original version
+ of the Work, provide any support, including (but not limited to)
+ the reporting and handling of errors, to recipients of the
+ Derived Work unless those persons have stated explicitly that
+ they do provide such support for the Derived Work.
+
+ d. You distribute at least one of the following with the Derived Work:
+
+ 1. A complete, unmodified copy of the Work;
+ if your distribution of a modified component is made by
+ offering access to copy the modified component from a
+ designated place, then offering equivalent access to copy
+ the Work from the same or some similar place meets this
+ condition, even though third parties are not compelled to
+ copy the Work along with the modified component;
+
+ 2. Information that is sufficient to obtain a complete,
+ unmodified copy of the Work.
+
+7. If you are not the Current Maintainer of the Work, you may
+distribute a Compiled Work generated from a Derived Work, as long as
+the Derived Work is distributed to all recipients of the Compiled
+Work, and as long as the conditions of Clause 6, above, are met with
+regard to the Derived Work.
+
+8. The conditions above are not intended to prohibit, and hence do not
+apply to, the modification, by any method, of any component so that it
+becomes identical to an updated version of that component of the Work as
+it is distributed by the Current Maintainer under Clause 4, above.
+
+9. Distribution of the Work or any Derived Work in an alternative
+format, where the Work or that Derived Work (in whole or in part) is
+then produced by applying some process to that format, does not relax or
+nullify any sections of this license as they pertain to the results of
+applying that process.
+
+10. a. A Derived Work may be distributed under a different license
+ provided that license itself honors the conditions listed in
+ Clause 6 above, in regard to the Work, though it does not have
+ to honor the rest of the conditions in this license.
+
+ b. If a Derived Work is distributed under a different license, that
+ Derived Work must provide sufficient documentation as part of
+ itself to allow each recipient of that Derived Work to honor the
+ restrictions in Clause 6 above, concerning changes from the Work.
+
+11. This license places no restrictions on works that are unrelated to
+the Work, nor does this license place any restrictions on aggregating
+such works with the Work by any means.
+
+12. Nothing in this license is intended to, or may be used to, prevent
+complete compliance by all parties with all applicable laws.
+
+
+NO WARRANTY
+===========
+
+There is no warranty for the Work. Except when otherwise stated in
+writing, the Copyright Holder provides the Work `as is', without
+warranty of any kind, either expressed or implied, including, but not
+limited to, the implied warranties of merchantability and fitness for a
+particular purpose. The entire risk as to the quality and performance
+of the Work is with you. Should the Work prove defective, you assume
+the cost of all necessary servicing, repair, or correction.
+
+In no event unless required by applicable law or agreed to in writing
+will The Copyright Holder, or any author named in the components of the
+Work, or any other party who may distribute and/or modify the Work as
+permitted above, be liable to you for damages, including any general,
+special, incidental or consequential damages arising out of any use of
+the Work or out of inability to use the Work (including, but not limited
+to, loss of data, data being rendered inaccurate, or losses sustained by
+anyone as a result of any failure of the Work to operate with any other
+programs), even if the Copyright Holder or said author or said other
+party has been advised of the possibility of such damages.
+
+
+MAINTENANCE OF THE WORK
+=======================
+
+The Work has the status `author-maintained' if the Copyright Holder
+explicitly and prominently states near the primary copyright notice in
+the Work that the Work can only be maintained by the Copyright Holder
+or simply that it is `author-maintained'.
+
+The Work has the status `maintained' if there is a Current Maintainer
+who has indicated in the Work that they are willing to receive error
+reports for the Work (for example, by supplying a valid e-mail
+address). It is not required for the Current Maintainer to acknowledge
+or act upon these error reports.
+
+The Work changes from status `maintained' to `unmaintained' if there
+is no Current Maintainer, or the person stated to be Current
+Maintainer of the work cannot be reached through the indicated means
+of communication for a period of six months, and there are no other
+significant signs of active maintenance.
+
+You can become the Current Maintainer of the Work by agreement with
+any existing Current Maintainer to take over this role.
+
+If the Work is unmaintained, you can become the Current Maintainer of
+the Work through the following steps:
+
+ 1. Make a reasonable attempt to trace the Current Maintainer (and
+ the Copyright Holder, if the two differ) through the means of
+ an Internet or similar search.
+
+ 2. If this search is successful, then enquire whether the Work
+ is still maintained.
+
+ a. If it is being maintained, then ask the Current Maintainer
+ to update their communication data within one month.
+
+ b. If the search is unsuccessful or no action to resume active
+ maintenance is taken by the Current Maintainer, then announce
+ within the pertinent community your intention to take over
+ maintenance. (If the Work is a LaTeX work, this could be
+ done, for example, by posting to comp.text.tex.)
+
+ 3a. If the Current Maintainer is reachable and agrees to pass
+ maintenance of the Work to you, then this takes effect
+ immediately upon announcement.
+
+ b. If the Current Maintainer is not reachable and the Copyright
+ Holder agrees that maintenance of the Work be passed to you,
+ then this takes effect immediately upon announcement.
+
+ 4. If you make an `intention announcement' as described in 2b. above
+ and after three months your intention is challenged neither by
+ the Current Maintainer nor by the Copyright Holder nor by other
+ people, then you may arrange for the Work to be changed so as
+ to name you as the (new) Current Maintainer.
+
+ 5. If the previously unreachable Current Maintainer becomes
+ reachable once more within three months of a change completed
+ under the terms of 3b) or 4), then that Current Maintainer must
+ become or remain the Current Maintainer upon request provided
+ they then update their communication data within one month.
+
+A change in the Current Maintainer does not, of itself, alter the fact
+that the Work is distributed under the LPPL license.
+
+If you become the Current Maintainer of the Work, you should
+immediately provide, within the Work, a prominent and unambiguous
+statement of your status as Current Maintainer. You should also
+announce your new status to the same pertinent community as
+in 2b) above.
+
+
+WHETHER AND HOW TO DISTRIBUTE WORKS UNDER THIS LICENSE
+======================================================
+
+This section contains important instructions, examples, and
+recommendations for authors who are considering distributing their
+works under this license. These authors are addressed as `you' in
+this section.
+
+Choosing This License or Another License
+----------------------------------------
+
+If for any part of your work you want or need to use *distribution*
+conditions that differ significantly from those in this license, then
+do not refer to this license anywhere in your work but, instead,
+distribute your work under a different license. You may use the text
+of this license as a model for your own license, but your license
+should not refer to the LPPL or otherwise give the impression that
+your work is distributed under the LPPL.
+
+The document `modguide.tex' in the base LaTeX distribution explains
+the motivation behind the conditions of this license. It explains,
+for example, why distributing LaTeX under the GNU General Public
+License (GPL) was considered inappropriate. Even if your work is
+unrelated to LaTeX, the discussion in `modguide.tex' may still be
+relevant, and authors intending to distribute their works under any
+license are encouraged to read it.
+
+A Recommendation on Modification Without Distribution
+-----------------------------------------------------
+
+It is wise never to modify a component of the Work, even for your own
+personal use, without also meeting the above conditions for
+distributing the modified component. While you might intend that such
+modifications will never be distributed, often this will happen by
+accident -- you may forget that you have modified that component; or
+it may not occur to you when allowing others to access the modified
+version that you are thus distributing it and violating the conditions
+of this license in ways that could have legal implications and, worse,
+cause problems for the community. It is therefore usually in your
+best interest to keep your copy of the Work identical with the public
+one. Many works provide ways to control the behavior of that work
+without altering any of its licensed components.
+
+How to Use This License
+-----------------------
+
+To use this license, place in each of the components of your work both
+an explicit copyright notice including your name and the year the work
+was authored and/or last substantially modified. Include also a
+statement that the distribution and/or modification of that
+component is constrained by the conditions in this license.
+
+Here is an example of such a notice and statement:
+
+ %% pig.dtx
+ %% Copyright 2005 M. Y. Name
+ %
+ % This work may be distributed and/or modified under the
+ % conditions of the LaTeX Project Public License, either version 1.3
+ % of this license or (at your option) any later version.
+ % The latest version of this license is in
+ % http://www.latex-project.org/lppl.txt
+ % and version 1.3 or later is part of all distributions of LaTeX
+ % version 2005/12/01 or later.
+ %
+ % This work has the LPPL maintenance status `maintained'.
+ %
+ % The Current Maintainer of this work is M. Y. Name.
+ %
+ % This work consists of the files pig.dtx and pig.ins
+ % and the derived file pig.sty.
+
+Given such a notice and statement in a file, the conditions
+given in this license document would apply, with the `Work' referring
+to the three files `pig.dtx', `pig.ins', and `pig.sty' (the last being
+generated from `pig.dtx' using `pig.ins'), the `Base Interpreter'
+referring to any `LaTeX-Format', and both `Copyright Holder' and
+`Current Maintainer' referring to the person `M. Y. Name'.
+
+If you do not want the Maintenance section of LPPL to apply to your
+Work, change `maintained' above into `author-maintained'.
+However, we recommend that you use `maintained', as the Maintenance
+section was added in order to ensure that your Work remains useful to
+the community even when you can no longer maintain and support it
+yourself.
+
+Derived Works That Are Not Replacements
+---------------------------------------
+
+Several clauses of the LPPL specify means to provide reliability and
+stability for the user community. They therefore concern themselves
+with the case that a Derived Work is intended to be used as a
+(compatible or incompatible) replacement of the original Work. If
+this is not the case (e.g., if a few lines of code are reused for a
+completely different task), then clauses 6b and 6d shall not apply.
+
+
+Important Recommendations
+-------------------------
+
+ Defining What Constitutes the Work
+
+ The LPPL requires that distributions of the Work contain all the
+ files of the Work. It is therefore important that you provide a
+ way for the licensee to determine which files constitute the Work.
+ This could, for example, be achieved by explicitly listing all the
+ files of the Work near the copyright notice of each file or by
+ using a line such as:
+
+ % This work consists of all files listed in manifest.txt.
+
+ in that place. In the absence of an unequivocal list it might be
+ impossible for the licensee to determine what is considered by you
+ to comprise the Work and, in such a case, the licensee would be
+ entitled to make reasonable conjectures as to which files comprise
+ the Work.

+work as expected).</li>
+<li>Blank lines after a <code>\begin{question}</code> no longer
+result in extra space.</li>
+<li>Adjust spacing and layout of front page (again); various other
+cosmetic changes.</li>
+<li>A document identifier appears at the bottom of each page,
+corroborating the exam the page is for (to avoid photocopier collation
+accidents), and giving a numeric identifier which increases with time
+(allowing you to identify which of two printouts is later).</li>
+</ul></dd>
+
+<dt>1.0.4, 2013 March 6</dt>

+option was present. Fixed, by special-casing, specifically disabling the

+space, since <code>\partmarks</code> is now fully in the margin).</li>

+</ul></dd>
+
+<dt>1.0.1, 2013 January 18</dt>
+<dd><ul>
+<li><code>{figure}</code> now works, because it's explicitly

+before). The contents don't float.</li>
+<li>Layout adjustments.</li>
+<li>Graphics now appear in draft mode.</li>
+</ul>
+</dd>
+
+<dt>1.0, 2012 December 11</dt>
+<dd>This is the nominal version 1.0 release, and will be used for the
+2012-13 Honours Astronomy exams (it might get further tweaks along the
+way, but we believe this is a complete distribution set).<ul>
+<li>More adjustments to notes-for-authors, now showing example LaTeX results.</li>
+<li>Addition of template-question.tex</li>
+<li>Adjustments to base rubric.</li>
+</ul></dd>
+
+<dt>1.0b5, 2012 December 3</dt>
+<dd><ul>

+<li>Add macro <code>\shout</code>, for highlighted `FIXME' comments.</li>
+<li>Add showmarktotals option.</li>
+<li>Permit <code>\partmarks</code> in solutions, without it adding to
+the marks added up for the question (at the same time, forbid having a
+solution within a solution).</li>
+<li>Various formatting adjustments.</li>
+</ul>
+</dd>
+
+<dt>1.0b3, 2012 November 8</dt>
+<dd><ul>
+<li>Add [A345] option.</li>

+<li>Some packaging changes and bugfixes.</li>

+<dt>1.0b2, 2012 November 6</dt>
+<dd>Mild formatting adjustments.</dd>
+
+<dt>1.0rc1, 2012 November 2</dt>
+<dd><ul>
+<li>Significant rewrite of formatting, producing a consensus
+AandA/PhysHons style, and renaming some confusingly named
+commands.</li>
+<li>Consequently, the AandA.clo and PhysHons.clo options have
+disappeared.</li>
+<li>The <code>\constantssheet</code> macro has appeared, and setting
+this is now the principal function of per-class <code>.clo</code>
+files.
+See the new <code>A1.clo</code> and modified <code>P2.clo</code> option files.</li>
+</ul>
+</dd>
+
+<dt>0.17.1, 2012 September 21</dt>
+<dd>Fix packaging infelicity</dd>
+
+<dt>0.17, 2012 September 21</dt>
+<dd><ul>
+<li>Rework <code>solutions</code> environment to make it a little more robust.</li>
+<li>Add <code>\MSc</code> degree shorthand.</li>
+<li>Bugfix: continuation headers now appear if a question starts on page 1.</li>
+<li>Bugfix: fix wrong syntax in draft+showsolutions mode -- now works again</li>
+</ul>
+</dd>
+
+<dt>0.16, 2012 July 26</dt>
+<dd><ul>
+<li>Renamed the [showmarks] option to more rational [perquestionmarks]
+(because the option doesn't control whether per-question marks are
+<em>displayed</em>, but whether they're tracked at all). Slightly
+improved the documentation of this at the same time.</li>
+<li>Added <code>\lambdabar</code> macro</li>
+<li>Fix long-standing problem with continuation lines -- these should now be robust.</li>
+</ul></dd>
+<dt>0.15, 2011 November 23</dt>
+<dd>Avoid conflict with <code>ifpdf</code> package.
+Now <em>depends</em> on <code>ifpdf</code>.</dd>
+<dt>0.14, 2010 August 6</dt>
+<dd><ul>
+<li>Fixed the problem where the question-continuation marks would be
+messed up by the presence of floats.</li>
+<li>Added P2.clo; adjust 'showing solutions' banner
+to avoid collision with other headers (thanks to Morag Casey for the .clo
+file and the report).</li>
+<li>Changed the name of the class to 'guexam', from potentially confusing 'exam'.
+Support guexam.config for forcing options (for example).</li>
+</ul></dd>
+
+<dt>0.13-1, 2008 November 21</dt>
+<dd>Make the gulogo style optional, so that question authors don't
+have to download and install that before they can draft a question.
+Also adjust the logo size.</dd>
+
+<dt>0.13, 2008 November 11</dt>
+<dd>Add university logo, and slightly rearrange the header.
+Add <code>{questiondata}</code> environment.</dd>
+
+<dt>0.12-2, 2008 April 14</dt>
+<dd>...keep on truckin'. Further changes to the
+<code>\partmarks*</code> spacing code, still largely unprincipled, but
+looking closer to what's required.</dd>
+
+<dt>0.12-1, 2008 April 3</dt>
+<dd>...and again. This time, I think I actually see what the problem
+was. Macro <code>\partmarks</code> now forces a new paragraph (it was
+documented to be usable at the end of a paragraph, so this is again
+forced, and the documentation made more explicit), this makes what I
+thought was the solution actually work. Which is nice. Redefined
+<code>enumerate</code> and <code>itemize</code> environments, to
+improve spacing somewhat.</dd>
+
+<dt>0.12, 2008 April 3</dt>
+<dd>Further adjustments to <code>\partmarks</code>: again, it should
+be more consistent without necessarily being more principled, alas.</dd>
+
+<dt>0.11, 2008 March 30</dt>
+<dd>Minor fixes: Adjust display of partmarks -- should now be more
+consistent; option [showsolutions] no longer defaults
+[{no,}pageperquestion]; add macro <code>\e</code> to format roman
+exponential.</dd>
+
+<dt>0.10, 2008 January 17</dt>
+<dd>Fix <code>\vec</code> when it appears in sub- or superscript
+position. Add <code>\paperident</code> command.</dd>
+
+<dt>0.9, 2007 December 10</dt>
+<dd>Various formatting changes. Added optional argument to
+<code>\includequestion</code> overriding question number.</dd>
+
+<dt>0.8, 2007 November 25</dt>
+<dd>You can now use <code>\usepackage</code> within
+<code>[compose]</code> mode.</dd>
+
+<dt>0.7, 2007 November 20</dt>
+<dd>Make changes to the display of the 'University of Glasgow' banner
+at the top: resolves some font problems. Other minor layout tweaks.</dd>
+
+<dt>0.6, 2007 November 18</dt>
+<dd>Fixed bold maths problems: <code>\vec</code> now works with greek
+letters, too. Support MTpro2 (mathtime maths fonts) with the new
+<code>[mtpro2]</code> class option. The <code>{solution}</code>
+environment can appear multiple times within a question. Question
+numbers now appear correctly in 'final' mode.</dd>
+
+<dt>0.5, 2007 October 30</dt>
+<dd>Fix collision with LaTeX internal: a <code>\comment</code> at the
+start of a <code>{question}</code> now works.</dd>

+\begin{question}{30} \comment{by Andrew Davies}

+\Diffl {}t (\rho c^2R^3)=-p\Diffl {R^3}t,
+\end{gather*}
+Discuss briefly the meaning of each of $H$, $\rho$ , $k$ and
+$\Lambda$. \partmarks{4}
+
+Suppose the Universe consists of a single substance with equation
+of state $p=w\rho c^2$, where $ w=$constant. Consider the
+following cases, with $k=\Lambda=0$:
+
+\part For $w = 0$, find the relation between $R$ and $\rho$. Hence
+show that $H=\frac{2}{3t}$. What is the physical interpretation of
+this case?
+\partmarks{8}
+
+\part In the case $w=-1$ , show that $H = $constant and $R = A \exp(Ht)$,
+with $A$ constant.
+\partmarks{4}

+\part Explain how the case, $w=-1$, $k=\Lambda=0$, $\rho=0$ is
+equivalent to an empty, flat, Universe with a non-zero $\Lambda$.
+\partmarks{2}
+
+\part Consider a model Universe which contained matter with equation
+of state with $w = 0$ for $0 < t < t_0$, but which changes to
+$W=0$ for $t\ge t_0$ without any discontinuity in $H(t)$.
+Regarding this second stage as driven by a non-zero $\Lambda$ what
+is the value of $\Lambda$ if $t_0 = 10^{24}$\units{\mu s}? Define the
+dimensionless deceleration parameter, $q$, and find its value
+before and after $t_0$.
+\shout{Shout it loud: I'm a geek and I'm proud}
+\partmarks{8}
+
+Note: that's
+\[
+t_0=10^{24}\units{\mu s}\qquad\text{with a letter mu: $\mu$}.

+ \langle n_i(n_i-1) \rangle = \lambda^2.

+The pixels values are summed in columns. Show that these sums,
+$S_j$, will be drawn from a parent probability distribution that is
+approximately
+\begin{equation*} p(S_j|\lambda)=\frac{1}{\sqrt{2\pi

+clearly stating any theorems you use.

+$\lambda$, justifying any assumptions you make.
