+	  <title>Log options</title>
+	  <p>With the <c>logopts</c> start flag, it's possible to specify
+	  options that modify some aspects of the logging behaviour.
+	  Currently, the following options are available:</p>
+	  <list>
+	    <item><c>no_src</c></item>
+	    <item><c>no_nl</c></item>
+	  </list>
+	  <p>With <c>no_src</c>, the html version of the test suite source
+	  code will not be generated during the test run (and consequently
+	  not be available in the log file system).</p>
+	  <p>With <c>no_nl</c>, Common Test will not add a newline character
+	  (\n) to the end of an output string that it receives from a call to e.g.
+	  <c>io:format/2</c>, and which it prints to the test case log.</p>
+	  <p>For example, if a test is started with:</p>
+	  <p><c>$ ct_run -suite my_SUITE -logopts no_src</c></p>
+	  <p>then printouts during the test made by successive calls to <c>io:format("x")</c>,
+	  will appear in the test case log as:</p>
+	  <p><c>xxx</c></p>
+	  <p>instead of each <c>x</c> printed on a new line, which is the default behaviour.</p>
