title: gnuplot arguments in a Homebrew installation
body: <p>Upon installing <em>gnuplot</em> on my Mac with <em>Homebrew</em> I noticed that it passes many arguments to the <code>configure</code> file. More precisely, this is the output I was getting on the terminal</p>
  
  <pre><code>$ brew install gnuplot

  Already downloaded: /Library/Caches/Homebrew/gnuplot-4.6.3.tar.gz
  ==&gt; ./configure --prefix=/usr/local/Cellar/gnuplot/4.6.3 --with-readline=/usr/local/opt/readline --with-gd=/usr/local/opt/gd --disable-wxwidgets --without-cairo --without-latex --without-tutorial
  </code></pre>
  
  <p>Then I understood why what I had on my <em>Mac</em> was such a <em>poorer</em> version of what I have on my <em>Ubuntu</em>. Therefore, browsing the net I found that for being able to use the <code>wxt</code> terminal I need to add the <code>--wx</code> flag for the installation. Moreover it was suggested to use also <code>--pdf</code> and <code>--with-x</code>. Visually parsing the output I had on screen (which I pasted above), I made up other flags, such as <code>--cairo</code> and <code>--tutorial</code>, and I got the following output</p>
  
  <pre><code>$ brew install gnuplot --wx --cairo --pdf --with-x --tutorial

  ==&gt; make
  ==&gt; make install

  <p>Now my question is: where the heck could I find a list of acceptable arguments to use for a <em>Homebrew</em> installation, such as the one here for <em>gnupot</em>? Moreover, somehow it didn't accept my <code>--tutorial</code> :(</p>
