title: How to add comments to an Exuberant Ctags config file?
body: <p>What character can I use to put comments in an Exuberant Ctags <code>.ctags</code> file?</p>
  
  <p>I would like to add comments with explanations, and perhaps to disable some regexps.</p>
  
  <p>But I can't find any comment character which ctags-exuberant accepts!<br>
  I keep getting the warning:</p>
  
  <pre><code>ctags: Warning: Ignoring non-option in /home/joey/.ctags
  </code></pre>
  
  <p>which is better than an error, but still a little annoying.</p>
  
  <p>I have tried <code>#</code> <code>//</code> <code>/* ... */</code> and <code>;</code> as comments, but ctags tries to parse them all!</p>
  
  <p>Here is an example file with some comments which ctags will complain about:</p>
  
  <pre><code># Add some more rules for Javascript
  --langmap=javascript:+.jpp
