040 <p>IndexShapeFile is an application that can be used to index an ESRI ShapeFiles(tm).
041 It indexes both the geometry and the alphanumeric attributes</p>
042
043 <p>The application shows a file chooser with which the user can select a file. When a file
044 is choosen the application opens it and shows the attributes. The user can now select the
045 attributes that has to be indexed. Already indexed attributes are already selected and can
046 be deselected. For alphanumeric attributes the user can indicate if the attribute is unique or not.</p>
047
048 <p>After selecting the attributes the application creates the needed indexes and loops over all the
049 features in the shape file. For every feature the application inserts the attributes in the right index.
050 After looping over the features the application closes the shapefile and the created indexes and removes the indexes
051 that are no longer needed (eg. the index for the attributes that are deselected).</p>
052
053 <p>It is not possible to transform a unique index to a non-unique index or back.</p>
