<p>
  
  Connection to an LTPDA Repository is normally carried out as part of other processes. For example, when submitting an 
  object to the repository using the <tt>submit</tt> command, the user is prompted to login to the chosen repository.
</p>
<p>
  It is also possible to connect to a repository using a script interface. The result is a connection object which can 
  be passed to other methods (for example, <tt>submit</tt>), thus allowing the construction of more automated procedures
  for interacting with repositories.
</p>
<p>
  To connect to a repository using the script interface, us the command <tt>utils.jmysql.connect</tt>. It takes the following input arguments:

  <table border="1" cellpadding="2" width="30%" bgcolor="#DDDDDD">
    <tr valign="top">
      <td><tt>hostname</tt></td><td>A hostname for the repository</td>
    </tr>
    <tr valign="top">
      <td><tt>dbname</tt></td><td>A database name to connect to</td>
    </tr>
    <tr valign="top">
      <td><tt>username</tt></td><td>[optional] A username to connect with</td>
    </tr>
    <tr valign="top">
      <td><tt>username</tt></td><td>[optional] A password to connect with</td>
    </tr>
  </table>
  
  <br> If you don't supply them as input arguments, you will then be prompted for a 
  valid username and password.
<br>
The result is a <tt>mpipeline.repository.RepositoryConnection</tt> object which can be further used to interact with the repository.
<br>
To disconnect from the server, use the <tt>closeConnection</tt> method of the <tt>mpipeline.repository.RepositoryConnection</tt> class:

<div class="fragment"><pre>
	>> conn.closeConnection
</pre></div>
