<h4 class="subsection">14.3.1 Not Ending a Sentence</h4>

<p><a name="index-Not-ending-a-sentence-662"></a><a name="index-Sentence-non_002dending-punctuation-663"></a><a name="index-Periods_002c-inserting-664"></a>Depending on whether a period or exclamation point or question mark is
inside or at the end of a sentence, less or more space is inserted after
a period in a typeset manual.  Since it is not always possible
to determine when a period ends a sentence and when it is used
in an abbreviation, special commands are needed in some circumstances. 
Usually, Texinfo can guess how to handle periods, so you do not need to
use the special commands; you just enter a period as you would if you
were using a typewriter, which means you put two spaces after the
period, question mark, or exclamation mark that ends a sentence.

  <p><a name="index-g_t_003ccolon_003e-_0040r_007b_0028suppress-end_002dof_002dsentence-space_0029_007d-665"></a>Use the <code>@:</code> command after a period, question mark,
exclamation mark, or colon that should not be followed by extra space. 
For example, use <code>@:</code> after periods that end abbreviations
which are not at the ends of sentences.

  <p>For example,

<pre class="example">     foo vs.@: bar
     foo vs. bar
</pre>
  <p class="noindent">produces

  <blockquote>
foo vs. bar <br>
foo vs. bar
</blockquote>

<p class="noindent"><code>@:</code> has no effect on the Info and HTML output.  In Docbook and
XML, the previous punctuation character (.?!:) is output as an entity
instead of as the normal character: &lsquo;<samp><span class="samp">&amp;period; &amp;quest; &amp;excl;
&amp;colon;</span></samp>&rsquo;.  This gives further processors a chance to notice and not
add the usual extra space.

  <p>Do not put braces after <code>@:</code> (or any non-alphabetic command).
