This means that once the database has been set up, +each year you can easily create a new problem sheet that is sufficiently +different from the previous year, thus preventing the temptation of current +students seeking out the previous year’s students, and checking out their +answers. There is also an option that can be passed to the package +to determine whether or not the solutions should be printed. In this +way, one file can either produce the student’s version or the teacher’s version. </p><!--l. 56--><p class="noindent" > </p> <!--l. 56--><p class="noindent" ><a -href="#top">Top</a></p><h3 class="sectionHead"><span class="titlemark">2 </span> <a +href="#top">Top</a></p><h3 class="sectionHead"><span class="titlemark">2 </span> <a id="x1-30002"></a>Package Options</h3> <!--l. 57--><p class="noindent" >The following options may be passed to this package: </p><dl class="description"><dt class="description"> <span -class="ec-lmssbx-10">answers</span><a +class="ec-lmssbx-10x-x-109">answers</span><a id="dx1-3001"></a> </dt><dd class="description">Show the answers </dd><dt class="description"> <span -class="ec-lmssbx-10">noanswers</span><a +class="ec-lmssbx-10x-x-109">noanswers</span><a id="dx1-3002"></a> </dt><dd class="description">Don’t show the answers (default) </dd><dt class="description"> <span -class="ec-lmssbx-10">draft</span><a +class="ec-lmssbx-10x-x-109">draft</span><a id="dx1-3003"></a> </dt><dd class="description">Display the label and dataset name when a problem is used </dd><dt class="description"> <span -class="ec-lmssbx-10">final</span><a +class="ec-lmssbx-10x-x-109">final</span><a id="dx1-3004"></a> </dt><dd class="description">Don’t display label and dataset name when a problem is used </dd><dt class="description"> <span -class="ec-lmssbx-10">usedefaultargs</span><a +class="ec-lmssbx-10x-x-109">usedefaultargs</span><a id="dx1-3005"></a> </dt><dd class="description">Make <span -class="ec-lmtt-10">\thisproblem</span><a - id="dx1-3006"></a> use the default arguments supplied in the - problem definition. +class="ec-lmtt-10x-x-109">\thisproblem</span><a + id="dx1-3006"></a> use the default arguments supplied in + the problem definition. + + </dd><dt class="description"> <span -class="ec-lmssbx-10">nousedefaultargs</span><a +class="ec-lmssbx-10x-x-109">nousedefaultargs</span><a id="dx1-3007"></a> </dt><dd -class="description">Make <span -class="ec-lmtt-10">\thisproblem</span><a - id="dx1-3008"></a> prompt for problem arguments (default).</dd></dl> +class="description">Make <span +class="ec-lmtt-10x-x-109">\thisproblem</span><a + id="dx1-3008"></a> prompt for problem arguments + (default).</dd></dl> <!--l. 69--><p class="noindent" > </p> <!--l. 69--><p class="noindent" ><a -href="#top">Top</a></p><h3 class="sectionHead"><span class="titlemark">3 </span> <a +href="#top">Top</a></p><h3 class="sectionHead"><span class="titlemark">3 </span> <a id="x1-40003"></a>Verbatim</h3> -<!--l. 71--><p class="noindent" >As from version 3.02, problems and solutions may contain verbatim text, but you must -use the <a +<!--l. 71--><p class="noindent" >As from version 3.02, problems and solutions may contain verbatim text, but +you must use the <a id="dx1-4001"></a><span -class="ec-lmtt-10">fragile </span>(or <span -class="ec-lmtt-10">fragile=true</span>) option for the associated environments. -</p><!--l. 75--><p class="indent" > Alternatively, if most of your problems contain verbatim, you can globally set this -option using: +class="ec-lmtt-10x-x-109">fragile </span>(or <span +class="ec-lmtt-10x-x-109">fragile=true</span>) option for the associated +environments. +</p><!--l. 75--><p class="indent" > Alternatively, if most of your problems contain verbatim, you can globally set +this option using: - </p> - <div class="verbatim" id="verbatim-1"> + <div class="verbatim" id="verbatim-1"> \setkeys{probsoln}{fragile} </div> <!--l. 79--><p class="nopar" > You can switch off this option using <span -class="ec-lmtt-10">fragile=false</span>. -</p><!--l. 82--><p class="indent" > The <span -class="ec-lmtt-10">fragile </span>option writes information to a temporary file.
