title: How to install a package in LaTeX
body: <p>I'm fairly new to LaTeX, but have been using my own document template for a couple of years now to do basic typesetting. What I want to do is to add the <a href="http://tug.org/PSTricks/main.cgi?file=packages" rel="noreferrer">pst-gantt</a> package from PSTricks. </p>
  
  <p>I have never installed a new package before, but want it available to all of my projects. For the sake of completeness, I am running OSX10.6 and use TeXShop to edit text, however am slowly switching over to TextEdit.</p>
  
  <p>Anyway, I have googled and the results all say to use .dtx and .ins files (which I cannot find). If someone can give me some pointers as to what I need to install (do I need <a href="http://tug.org/PSTricks/main.cgi" rel="noreferrer">PSTricks</a> first?) and how to go about doing it, that would be great.</p>
  
  <p>Thanks</p>
