+/**
+ * Unique Field module for Drupal (unique_field)
+ * Compatible with Drupal 7.x
+ *
+ * By Joe Turgeon [http://arithmetric.com]

+
+The Unique Field module provides a way to require that specified fields
+or characteristics of a node are unique. This includes the node's title,
+author, language, taxonomy terms, and other fields.
+
+Without this module, Drupal and CCK do not prevent multiple nodes from
+having the same title or the same value in a given field.
+
+For example, if you have a content type with a Date field and there
+should only be one node per date, you could use this module to prevent a
+node from being saved with a date already used in another node.
+
+This module adds additional options to the administration page for each
+content type (i.e. admin/structure/types/manage/<content type>) for
+specifying which fields must be unique. The administrator may specify
+whether each field must be unique or whether the fields in combination must
+be unique. Also, the administrator can choose whether the fields must be
+unique among all other nodes or only among nodes from the given node's
+content type.
+
+Alternatively, you can select the 'single node' scope, which allows you
+to require that the specified fields are each unique on that node. For
+example, if a node has multiple, separate user reference fields, this
+setting will require that no user is selected more than once on one node.
