038     <p>IndexShapeFile is an application that can be used to index an ESRI ShapeFiles(tm).
039     It indexes both the geometry and the alphanumeric attributes</p>
040    
041     <p>The application shows a file chooser with which the user can select a file. When a file
042     is choosen the application opens it and shows the attributes. The user can now select the
043     attributes that has to be indexed. Already indexed attributes are already selected and can
044     be deselected. For alphanumeric attributes the user can indicate if the attribute is unique or not.</p>
045    
046     <p>After selecting the attributes the application creates the needed indexes and loops over all the
047     features in the shape file. For every feature the application inserts the attributes in the right index.
048     After looping over the features the application closes the shapefile and the created indexes and removes the indexes
049     that are no longer needed (eg. the index for the attributes that are deselected).</p>
050    
051     <p>It is not possible to transform a unique index to a non-unique index or back.</p>
