 886 <p>The <em>compound</em> directive is used to create a &quot;compound paragraph&quot;, which
 887 is a single logical paragraph containing multiple physical body

 889 <div class="compound">
 890 <p>The 'rm' command is very dangerous.  If you are logged
 891 in as root and enter</p>
 892 <pre class="literal-block">cd /
 893 rm -rf *</pre>
 894 <p>you will erase the entire contents of your file system.</p>
 895 </div>
 896 <p>Test the handling and display of compound paragraphs:</p>
 897 <div class="some-class compound">
 898 <p>Compound 2, paragraph 1,</p>
 899 <p>compound 2, paragraph 2,</p>
 900 <ul class="simple">

1005 is turned off using the <span class="docutils literal"><span class="pre">syntax-highlight</span></span> config setting in the test
1006 conversions in order to get identical results with/without installed
1007 Pygments highlighter.)</p>

1009 <p>The <span class="docutils literal"><span class="pre">:number-lines:</span></span> option (with optional start value) generates line

1014 <p>For inline code snippets, there is the <cite>code</cite> role, which can be used
1015 directly (the code will not be parsed/tagged, as the language is not known)
1016 or as base for special code roles, e.g. the LaTeX code in the next
