-Org-Drill is an extension for <a href="http://orgmode.org/";>Org mode</a>. 
Org-Drill uses a <a 
href="http://en.wikipedia.org/wiki/Spaced_repetition";>spaced repetition</a>
-algorithm to conduct interactive "drill sessions", using org files as sources
-of facts to be memorised. Each topic is treated as a "flash card". The material
-to be remembered is presented to the student in random order. The student rates
-his or her recall of each item, and this information is used to schedule the
-item for later revision.
-</p>
-<p>
-Each drill session can be restricted to topics in the current buffer
-(default), one or several files, all agenda files, or a subtree. A single
-topic can also be drilled.
-</p>
-<p>
-Different "topic types" can be defined, which present their information to the
-student in different ways.
-</p>
-<p>
-For more on the spaced repetition algorithm, and examples of other programs
-that use it, see:
-</p><ul>
-<li><a href="http://supermemo.com/index.htm";>SuperMemo</a> (see descriptions 
of the SM2, SM5 and SM8 algorithms)

-</ul>

-<p>
-Org-Drill comes bundled with Org mode, in the "contrib" directory. Org-Drill
-also has its own repository, which is updated more regularly than the bundled
-version. The repository is at:

-<p>
-The easiest way is to customise the variable 'org-modules' (<code>M-x 
customize-variables RET org-modules</code>) and make sure 'drill' is
-ticked. Org-drill will then be loaded when you restart Emacs or restart
-Org-mode.
-</p>
-<p>
-For manual installation, put the following in your <code>.emacs</code>. You 
will also need
-to make sure that Org's "contrib/lisp" directory is in the emacs load-path.

-Load the file <a href="spanish.html">spanish.org</a>. Press <code>M-x</code> 
and run the function <code>org-drill</code>. Follow
-the prompts at the bottom of the screen.
-</p>
-<p>
-When the drill finishes, you can look at <code>spanish.org</code> to get some 
idea of how
-drill topics are written.

-<p>
-Org-Drill uses org mode topics as 'drill items'. To be used as a drill item,
-the topic must have a tag that matches the value of
-<code>org-drill-question-tag</code>. This is <code>:drill:</code> by default. 
Any other org topics
-will be ignored.
-</p>
-<p>
-Drill items can have other drill items as children. When a drill item is being
-tested, the contents of any child drill items will be hidden.
-</p>
-<p>
-You don't need to schedule the topics initially.  Unscheduled items are
-considered to be 'new' and ready for memorisation.
-</p>
-<p>
-How should 'drill topics' be structured? Any org topic is a legal drill topic
-&ndash; it will simply be shown with all subheadings collapsed, so that only 
the
-material beneath the main item heading is visible. After pressing a key, any
-hidden subheadings will be revealed, and you will be asked to rate your
-"recall" of the item.
-</p>
-<p>
-This will be adequate for some items, but usually you will want to write items
-where you have more control over what information is hidden from the user for
-recall purposes. For this reason, some other card types are defined, including:
-</p><ul>
-<li><a href="#sec-4-4">Two-sided cards</a>
-</li>
-<li><a href="#sec-4-5">Multi-sided cards</a>
-</li>
-<li><a href="#sec-4-6">Multi-cloze cards</a>
-</li>
-<li><a href="#sec-4-7">User-defined card types</a>
-</li>
-</ul>
-
-
-<p>
-<b>A note about comments:</b> In org mode, comment lines start with '#'. The 
rest of
-the line is ignored by Org (apart from some special cases). You may sometimes
-want to put material in comments which you do not want to see when you are
-being tested on the item. For this reason, comments are always rendered
-invisible while items are being tested.

-<h3 id="sec-4-1">Simple topics</h3>
-<div class="outline-text-3" id="text-4-1">
-
-
-
-<p>
-The simplest drill topic has no special structure. When such a topic is
-presented during a drill session, any subheadings are "collapsed" with their
-contents hidden. So, you could include the question as text beneath the main
-heading, and the answer within a subheading. For example:
-</p>
-
-
-
-<pre class="example">* Item                                   :drill:
-What is the capital city of Estonia?
-
-** The Answer
-Tallinn.
-</pre>
-
-
-<p>
-When this item is presented for review, the text beneath the main heading will
-be visible, but the contents of the subheading ("The Answer") will be hidden.

-<h3 id="sec-4-2">Cloze deletion</h3>
-<div class="outline-text-3" id="text-4-2">
-
-
-
-<p>
-Cloze deletion can be used in any drill topic regardless of whether it is
-otherwise 'simple', or is one of the specialised topic types discussed
-below. To use cloze deletion, one or more parts of the body of the topic is
-marked as <i>cloze text</i> by surrounding it with single square brackets, 
[like
-so]. When the topic is presented for review, the text within square brackets
-will be obscured. The text is then revealed after the user presses a key. For
-example:
-</p>
-
-
-
-
-<pre class="example">* Item                                   :drill:
-The capital city of Estonia is [Tallinn].
-</pre>
-
-
-<p>
-During review, the user will see:
-</p>
-<blockquote>
-
-<p>The capital city of Estonia is <font style="background-color: blue;" 
color="cyan">
-<tt>[&hellip;]</tt></font>.
-</p>
-</blockquote>
-
-
-<p>
-When the user presses a key, the text "Tallinn" will become visible.
-</p>
-

-
-<div id="outline-container-4-3" class="outline-3">
-<h3 id="sec-4-3">Clozed text hints</h3>
-<div class="outline-text-3" id="text-4-3">
-
-
-
-<p>
-Clozed text can contain a "hint" about the answer. If the text surrounded
-by single square brackets contains `||' (two vertical bars), all text
-after that character is treated as a hint. During testing, the hint text will
-be visible when the rest of the text is hidden, and invisible when the rest of
-the text is visible.
-</p>
-<p>
-Example:
-</p>
-
-
-
-<pre class="example">Type 1 hypersensitivity reactions are mediated by 
[immunoglobulin E||molecule]
-and [mast cells||cell type].
-</pre>
-
-
-<blockquote>
-
-<p>Type 1 hypersensitivity reactions are mediated by
-<font style="background-color: blue;" color="cyan">
-<tt>[molecule&hellip;]</tt></font>
-and <font style="background-color: blue;" color="cyan">

-<div class="outline-text-3" id="text-4-4">
-
-
-<p>
-The remaining topic types all use the topic property, 
<code>DRILL_CARD_TYPE</code>. This
-property tells <code>org-drill</code> which function to use to present the 
topic during
-review. If this property has the value <code>twosided</code> then the topic is 
treated as
-a "two sided card". When a two sided card is reviewed, <i>one of the first 
two</i>
-subheadings within the topic will be visible &ndash; all other
-subheadings will be hidden.
-</p>
-<p>
-Two-sided cards are meant to emulate the type of flipcard where either side is
-useful as test material (for example, a card with a word in a foreign language
-on one side, and its translation on the other).
-</p>
-<p>
-A two sided card can have more than 2 subheadings, but all subheadings after
-the first two are considered as "notes" and will always be hidden during topic
-review.

-In this example, the user will be shown the main text &ndash; "Translate this

-&ndash; and either 'la mujer', <i>or</i> 'the woman', at random. The section

-<div class="outline-text-3" id="text-4-6">
-
-
-
-<p>
-Often, you will wish to create cards out of sentences that express several
-facts, such as the following:
-</p>
-
-
-
-<pre class="example">The capital city of New Zealand is Wellington, which is 
located in the
-North Island and has a population of about 400,000.
-</pre>
-
-
-<p>
-There is more than one fact in this statement &ndash; you could create a single
-'simple' card with all the facts marked as cloze text, like so:
-</p>
-
-
-
-<pre class="example">The capital city of [New Zealand] is [Wellington], which 
is located in
-the [North||North/South] Island and has a population of about [400,000].
-</pre>
-
-
-<p>
-But this card will be difficult to remember. If you get just one of the 4
-hidden facts wrong, you will fail the card. A card like this is likely to
-become a <a href="#sec-8">leech</a>.
-</p>
-<p>
-A better way to express all these facts using 'simple' cards is to create
-several cards, with one fact per card. You might end up with something
-like this:
-</p>
-
-
-
-<pre class="example">* Fact
-The capital city of [New Zealand] is Wellington, which has a population of
-about 400,000.
-
-* Fact
-The capital city of New Zealand is [Wellington], which has a population of
-about 400,000.
-
-* Fact
-The capital city of New Zealand is Wellington, which has a population of
-about [400,000].
-
-* Fact
-The capital city of [New Zealand] is Wellington, which is located in the
-the North Island.
-
-* Fact
-The capital city of New Zealand is [Wellington], which is located in
-the North Island.
-
-* Fact
-The capital city of New Zealand is Wellington, which is located in
-the [North||North/South] Island.
-</pre>
-
-
-<p>
-However, this is really cumbersome. Multicloze card types exist for this
-situation. Multicloze cards behave like 'simple' cards, except that when there
-is more than one area marked as cloze text, some but not all of the areas
-can be hidden. There are several types of predefined multicloze card:
-</p>
-<ol>
-<li><code>hide1cloze</code> &ndash; one of the marked areas is hidden during 
review; the others
-   all remain visible. The hidden text area is chosen randomly at each review.
-   (Note: this type used to be called 'multicloze', and that card type is
-   retained as a synonym for 'hide1cloze'.)
-</li>
-<li><code>show1cloze</code> &ndash; only one of the marked areas is visible 
during review; all
-   the others are hidden. The hidden text area is chosen randomly at each
-   review.
-</li>
-<li><code>hide2cloze</code> &ndash; like hide1cloze, but 2 marked pieces of 
text will be hidden,
-   and the rest will be visible.
-</li>
-<li><code>show2cloze</code> &ndash; like show1cloze, but 2 marked pieces of 
text will be visible,
-   the rest are hidden.
-</li>
-</ol>
-
-
-<p>
-There are also some types of multicloze card where some pieces have an
-increased or decreased chance of being hidden. These are intended for use when
-studying languages: generally it is easy to translate a foreign-language
-sentence into your own language if you have met it before, but it is much
-harder to translate in the other direction. Therefore, you will want to test
-the harder direction more often.
-</p><ol>
-<li><code>hide1_firstmore</code> &ndash; only one of the marked pieces of text 
will be
-   hidden. 75% of the time (guaranteed), the <i>first</i> piece is hidden; the 
rest
-   of the time, one of the other pieces is randomly hidden.
-</li>
-<li><code>show1_firstless</code> &ndash; only one of the marked pieces of text 
will be
-   visible. Only 25% of the time (guaranteed) will the <i>first</i> piece will 
be
-   visible; the rest of the time, one of the other pieces is randomly visible.
-</li>
-<li><code>show1_lastmore</code> &ndash; only one of the marked pieces of text 
will be

-Finally, you can write your own emacs lisp functions to define new kinds of
-topics. Any new topic type will need to be added to
-<code>org-drill-card-type-alist</code>, and cards using that topic type will 
need to have
-it as the value of their <code>DRILL_CARD_TYPE</code> property. For examples, 
see the
-functions at the end of org-drill.el &ndash; these include:
-</p><ul>
-<li><code>org-drill-present-verb-conjugation</code>, which implements the 
'conjugate'
-  card type. This asks the user to conjugate a verb in a particular tense. It
-  demonstrates how the appearance of an entry can be completely altered during
-  a drill session, both during testing and during the display of the answer.
-</li>
-<li><code>org-drill-present-translate-number</code>, which uses a third-party 
emacs lisp
-  library (<a 
href="http://www.emacswiki.org/emacs/spell-number.el";>spell-number.el</a>) to 
prompt the user to translate random numbers
-  to and from any language recognised by that library.
-</li>
-<li><code>org-drill-present-spanish-verb</code>, which defines the new topic 
type
-  <code>spanish_verb</code>. This illustrates how a function can control which 
of an
-  item's subheadings are visible during the drill session.

-If the body of a drill item is completely empty (ignoring properties and child
-items), then the item will be skipped during drill sessions. The purpose of
-this behaviour is to allow you to paste in 'skeletons' of complex items, then
-fill in missing information later. For example, you may wish to include an
-empty drill item for each tense of a newly learned verb, then paste in the
-actual conjugation later as you learn each tense.
-</p>

-Note that if an item is empty, any child drill items will <b>not</b> be 
ignored,
-unless they are empty as well.

-<p>
-If you have an item with an empty body, but still want it to be included in a

-</p><ol>
-<li>Put a brief comment ('# &hellip;')  in the item body.

-To do this, run a <i>cram session</i> with the <code>org-drill-cram</code>

-From the Anki website, <a 
href="http://ichi2.net/anki/wiki/Leeches";>http://ichi2.net/anki/wiki/Leeches</a>:
-</p>
-<blockquote>
-
-<p>Leeches are cards that you keep on forgetting. Because they require so many
-reviews, they take up a lot more of your time than other cards.
-</p>
-</blockquote>
-
-
-<p>
-Like Anki, Org-Drill defines leeches as cards that you have "failed" many
-times. The number of times an item must be failed before it is considered a
-leech is set by the variable <code>org-drill-leech-failure-threshold</code> 
(15 by
-default). When you fail to remember an item more than this many times, the item
-will be given the <code>:leech:</code> tag.
-</p>
-<p>
-Leech items can be handled in one of three ways. You can choose how Org-Drill
-handles leeches by setting the variable <code>org-drill-leech-method</code> to 
one of the
-following values:
-</p><dl>
-<dt>nil</dt><dd>Leech items are tagged with the <code>leech</code> tag, but 
otherwise treated the
-         same as normal items.
-</dd>
-<dt>skip</dt><dd>Leech items are not included in drill sessions.
-</dd>
-<dt>warn</dt><dd>Leech items are still included in drill sessions, but a 
warning
-  message is printed when each leech item is presented.
-</dd>
-</dl>
-
-
-<p>
-The best way to deal with a leech is either to delete it, or reformulate it so
-that it is easier to remember, for example by splitting it into more than one
-card.

early algorithm, used in SuperMemo 2.0 (1988), which remains very

-<dt><a href="http://www.supermemo.com/english/ol/sm5.htm";>SM5</a> 
(default)</dt><dd>used in SuperMemo 5.0 (1989). This algorithm uses 'ease
-     factors' but also uses a persistent, per-user 'matrix of optimal factors'
-     which is also modified after each item repetition.
-</dd>
-<dt>Simple8</dt><dd>an experimental algorithm based on the <a 
href="http://www.supermemo.com/english/algsm8.htm";>SM8</a> algorithm. SM8 is 
used
-             in SuperMemo 8.0 (1998) and is almost identical to SM11 which is
-             used in SuperMemo 2002. Like SM5, it uses a matrix of optimal
-             factors. Simple8 differs from SM8 in that it does not adapt the
-             matrix to the individual user, though it does adapt each item's
-             'ease factor'.

-<div class="outline-text-4" id="text-9-6-2">
-
-
-
-<p>
-The intervals generated by the SM2 and SM5 algorithms are pretty
-deterministic. If you tend to add items in large, infrequent batches, the lack
-of variation in interval scheduling can lead to the problem of "lumpiness" --
-one day a large batch of items are due for review, the next there is almost
-nothing, a few days later another big pile of items is due, and so on.
-</p>
-<p>
-This problem can be ameliorated by adding some random "noise" to the interval
-scheduling algorithm. The author of SuperMemo actually recommends this approach
-for the SM5 algorithm, and Org-Drill's implementation uses <a 
href="http://www.supermemo.com/english/ol/sm5.htm";>his code</a>.
-</p>
-<p>
-To enable random "noise" for item intervals, set the variable

-The <code>learn fraction</code> is a global value which affects how quickly 
the intervals
-(times between each retest of an item) increase with successive repetitions,
-for <i>all</i> items. The default value is 0.5, and this is the value used in
-SuperMemo. For some collections of information, you may find that you are
-reviewing items too often (they are too easy and the workload is too high), or
-too seldom (you are failing them too often). In these situations, it is
-possible to alter the learn fraction from its default in order to increase or
-decrease the frequency of repetition of items over time. Increasing the value
-will make the time intervals grow faster, and lowering it will make them grow
-more slowly. The table below shows the growth in intervals (in days) with some

-To alter the learn fraction, put the following in your .emacs:

-<div class="outline-text-3" id="text-9-7">
-
-
-<p>
-Most of Org-Drill's customisation settings are safe as file-local
-variables. This means you can include a commented section like this at the end
-of your .org file to apply special settings when running a Drill session using
-that file:
-</p>
-
-
-
-<pre class="example"># Local Variables:
-# org-drill-maximum-items-per-session:    50
-# org-drill-spaced-repetition-algorithm:  simple8
-# End:
-</pre>
-
-
-<p>
-You can achieve the same effect by including the settings in the 'mode line'
-(this must be the <b>first line</b> in the file), like so:
-</p>
-
-
-
-<pre class="example"># -*- org-drill-maximum-items-per-session: 50; 
org-drill-spaced-repetition-algorithm: simple8 -*-
-</pre>
-
-
-<p>
-In either case you will need to reload the file for the changes to take effect.

-If you keep all your items in a single file, it may eventually get very
-large. The file will be slow to load, and Emacs may have trouble
-syntax-highlighting the file contents correctly.
-</p>
-<p>
-The easiest way to solve this problem is:
-</p><ol>
-<li>Move your file into its own dedicated directory.
-</li>
-<li>Divide the file into two or more smaller files.
-</li>
-<li>Within each file, set <code>org-drill-scope</code> to 'directory'. See
-   <a href="#sec-9-7">per-file settings</a> above for instructions about how 
to do this.

-<div class="outline-text-2" id="text-11">
-
-
-
-<p>
-Every drill item is automatically given a persistent unique "ID" the first time
-it is seen by Org-Drill. This means that if two different people subsequently
-edit or reschedule that item, Org-Drill can still tell that it is the same
-item. This in turn means that collections of items can be shared and edited in
-a collaborative manner.
-</p>
-<p>
-There are two commands that are useful in this regard:
-</p><ol>
-<li><code>org-drill-strip-all-data</code> - this command deletes all 
user-specific
-   scheduling data from every item in the current collection. (It takes the
-   same optional 'scope' argument as <code>org-drill</code> to define which 
items will
-   be processed by the command). User-specific data includes scheduling dates,
-   ease factors, number of failures and repetitions, and so on. All items are
-   reset to 'new' status. This command is useful if you want to share your
-   item collection with someone else.
-</li>
-<li><code>org-drill-merge-buffers</code> - When called from buffer A, it 
prompts you for
-   another buffer (B), which must also be loaded into Emacs. This command
-   imports all the user-specific scheduling data from buffer B into buffer A,
-   and deletes any such information in A. Matching items are identified by
-   their ID. Any items in B that do not exist in A are copied to A, in
-   the same hierarchical location if all the parent headings exist, otherwise
-   at the end of the buffer.
-</li>
-</ol>
-
-
-<p>
-An example scenario:
-</p>
-<p>
-Tim decides to learn Swedish using an item collection (<code>.org</code> file) 
made
-publically available by Jane.  (Before publishing it Jane used
-'org-drill-strip-all-data' to remove her personal scheduling data from the
-collection.)  A few weeks later, Jane updates her collection, adding new items
-and revising some old ones. Tim downloads the new collection and imports his
-progress from his copy of the old collection, using 'org-drill-merge-buffers',
-using the new collection as buffer A and the old one as buffer B. He can then
-discard the old copy. Any items HE added to HIS copy of the old collection
-(buffer B) will not be lost &ndash; they will be appended to his copy of the 
new
-collection.
-</p>
-<p>
-Of course the sharing does not need to be 'public'. You and a friend might be
-learning a language or some other topic together. You each maintain a card
-collection. Periodically your friend sends you a copy of their collection --
-you run <code>org-drill-merge-buffers</code> on it, always using your own 
collection as
-buffer B so that your own scheduling progress is carried over. Other times you
-send your friend a copy of your collection, and he or she follows the same
-procedure.

-<div class="outline-text-2" id="text-12">

-<p>
-An innovative feature of the program SuperMemo is so-called "incremental
-reading". This refers to the ability to quickly and easily make drill items
-from selected portions of text as you read an article (a web page for
-example). See <a href="http://www.supermemo.com/help/read.htm";>the SuperMemo 
website</a> for more on incremental reading.
-</p>
-<p>
-Much of the infrastructure for incremental reading is already provided by Org
-Mode, with the help of some other emacs packages. You can provide yourself with
-an incremental reading facility by using 'org-capture' alongside a package that
-allows you to browse web pages either in emacs (w3 or <a 
href="http://www.emacswiki.org/emacs/emacs-w3m";>emacs-w3m</a>) or in the
-external browser of your choice (<a 
href="http://orgmode.org/worg/org-contrib/org-protocol.php";>org-protocol</a>).
-</p>
-<p>
-Another important component of incremental reading is the ability to save your
-exact place in a document, so you can read it <i>incrementally</i> rather than 
all
-at once. There is a large variety of bookmarking packages for emacs which
-provide advanced bookmarking functionality: see the <a 
href="http://www.emacswiki.org/emacs/BookMarks";>Emacs Wiki</a> for details.
-Bookmarking exact webpage locations in an external browser seems to be a bit
-more difficult. For Firefox, the <a href="http://www.wired-marker.org/";>Wired 
Marker</a> addon works well.
-</p>
-<p>
-An example of using Org-Drill for incremental reading is given below. First,
-and most importantly, we need to define a couple of <code>org-capture</code> 
templates for
-captured facts.
-</p>
-
-
-
-<pre class="example">(setq org-capture-templates
-       `(("u"
-         "Task: Read this URL"
-         entry
-         (file+headline "tasks.org" "Articles To Read")
-         ,(concat "* TODO Read article: '%:description'\nURL: %c\n\n")
-         :empty-lines 1
-         :immediate-finish t)
-
-        ("w"
-         "Capture web snippet"
-         entry
-         (file+headline "my-facts.org" "Inbox")
-         ,(concat "* Fact: '%:description'        :"
-                  (format "%s" org-drill-question-tag)
-                  ":\n:PROPERTIES:\n:DATE_ADDED: %u\n:SOURCE_URL: 
%c\n:END:\n\n%i\n%?\n")
-         :empty-lines 1
-         :immediate-finish t)
-        ;; ...other capture templates...
-    ))
-</pre>
-
-
-<p>
-Using these templates and <code>org-protocol</code>, you can set up buttons in 
your web
-browser to:
-</p><ul>
-<li>Create a task telling you to read the URL of the currently viewed webpage
-</li>
-<li>Turn a region of selected text on a webpage, into a new fact which is saved
-  to whichever file and heading you nominate in the template. The fact will
-  contain a timestamp, and a hyperlink back to the webpage where you created
-  it.
-</li>
-</ul>
-
-
-<p>
-For example, suppose you are reading the Wikipedia entry on tuberculosis <a 
href="http://en.wikipedia.org/wiki/Tuberculosis";>here</a>.
-</p>
-<p>
-You read the following:
-</p>
-<blockquote>
-
-<p>The classic symptoms of tuberculosis are a chronic cough with blood-tinged
-sputum, fever, night sweats, and weight loss. Infection of other organs causes
-a wide range of symptoms. Treatment is difficult and requires long courses of
-multiple antibiotics. Antibiotic resistance is a growing problem in
-(extensively) multi-drug-resistant tuberculosis. Prevention relies on screening
-programs and vaccination, usually with Bacillus Calmette-Guérin vaccine.
-</p>
-</blockquote>
-
-
-<p>
-You decide you want to remember that "Bacillus Calmette-Guérin vaccine" is the
-name of the vaccine against tuberculosis. First, you select the `interesting'
-portion of the text with the mouse:
-</p>
-<blockquote>
-
-<p>The classic symptoms of tuberculosis are a chronic cough with blood-tinged
-sputum, fever, night sweats, and weight loss. Infection of other organs causes
-a wide range of symptoms. Treatment is difficult and requires long courses of
-multiple antibiotics. Antibiotic resistance is a growing problem in
-(extensively) multi-drug-resistant tuberculosis.
-<font style="background-color: yellow;">Prevention relies
-on screening programs and vaccination, usually with Bacillus Calmette-Guérin
-vaccine.</font>
-</p>
-</blockquote>
-
-
-<p>
-Then you press the button you created when setting up 
<code>org-protocol</code>, which is
-configured to activate the capture template "w: Capture web snippet". The
-selected text will be sent to Emacs, turned into a new fact using the template,
-and filed away for your later attention.
-</p>
-<p>
-(Note that it might be more efficient to turn the entire paragraph into a drill
-item &ndash; since it contains several important facts &ndash; then split it 
up into
-multiple items when you edit it later in Emacs.)
-</p>
-<p>
-Once you have had enough of reading the article, save your place, then go to
-your "fact" file in Emacs. You should see that each piece of text you selected
-has been turned into a drill item. Continuing the above example, you would see
-something like:
-</p>
-
-
-
-<pre class="example">** Fact: 'Tuberculosis - Wikipedia, the Free 
Encyclopedia'        :drill:
-
-Prevention relies on screening programs and vaccination, usually with Bacillus
-Calmette-Guérin vaccine.
-</pre>
-
-
-<p>
-You need to edit this fact so it makes sense independent of its context, as
-that is how it will be presented to you in future. The easiest way to turn the
-text into a 'question' is by cloze deletion. All you need to do is surround the
-'hidden' parts of the text with square brackets.
-</p>
-<pre class="example">
-Prevention of tuberculosis relies on screening programs and vaccination,
-usually with [Bacillus Calmette-Guérin vaccine].
-</pre>
-
-
-
-<p>
-You can of course define browser buttons that use several different "fact"
-templates, each of which might send its fact to a different file or subheading,
-or give it different tags or properties, for example.
