Soft link names are used to map synonyms to their respective node
 names.

 The normal default value for the synonym mapping directory in the
 DECdns directory service is:

   .DNA_NodeSynonym

 The default directory name can be changed using the preferences form.

 This directory contains the actual soft link names.  The name
 structure is:

   .DNA_NodeSynonym.<synonym>

 Where:

   <synonym>   is the Phase IV synonym name.

 For example, for the synonym "MYSYN", the fully specified soft link
 name is:

   .DNA_NodeSynonym.MYSYN
