 *  Display and Manage BOINC Application Versions
 * 
 * This page presents a form with information about application versions.
 * Some of the fields can be changed.   An application version can be deleted
 * by entering the word "DELETE" (all caps required) in the provided field.   
 * It is better to deprecate a version first than to delete it, but it is also 
 * good to remove old versions after they have been unused for a while,
 * lest you over-fill the feeder (which results in new versions not being
 * used by clients).
