  The user must enter the IDs of the objects he/she wishes to retrieve. The IDs
  can be entered using standard MATLAB numerical notation. Collections can be 
  retrieved by prefixing the collection ID with a 'c', for example, 'c12' retrieves
  collection 12.

  The objects can be directly saved to disk in XML format by clicking the 'Save' button.
</p>
<p>
  You can select a prefix for the objects by typing in the 'prefix' edit box.
</p>
<p>
  If the 'Append object type' check-box is checked, each object name (or filename) will
  have the object type (class) appended.
