+=head1 NAME
+
+RT::Condition::CustomFieldTransaction
+
+=head1 DESCRIPTION
+
+Returns true if a transaction changed the value of a custom field.  Unlike 
+CustomFieldChange, this condition doesn't care what the value was, only that 
+it changed.
+
+=head2 Parameters
+
+=over 4
+
+=item field (string)
+
+Only return true if the transaction changed a custom field with this name.  
+If empty, returns true for any CustomField-type transaction.
+
+=item include_create (boolean) - Also return true for Create-type transactions.
+If 'field' is specified, return true if that field is non-empty in the newly 
+created object.
+
+=back
+
+=head2 IsApplicable
+
+If the transaction has changed the value of a custom field.
+
+=head1 BUGS
+
+Probably interacts badly with multiple custom fields with the same name.
