+NCBI Entrez ELink
+=================
+
+Responds to a list of UIDs in a given database with either a list of related
+UIDs (and relevancy scores) in the same database or a list of linked UIDs in
+another Entrez database; checks for the existence of a specified link from a
+list of one or more UIDs; creates a hyperlink to the primary LinkOut provider
+for a specific UID and database, or lists LinkOut URLs and attributes for
+multiple UIDs.
