+    MAPPING
+
+    The mapping  feature is a  new addition.  It  allows you to  provide a
+    simple <tab>-delimited file containing mapping information.  Currently
+    mappings may be of the following types:
+
+        * simple
+            A  simple  mapping of  a  user-requested  ID into  one  or
+            several  other IDs  is performed  before querying  the DAS
+            server.  The IDs  in the result are then  mapped back into
+            the user-requested ID.
+
+          Format of map data file:
+
+            queryID,targetID
+
+          The  "queryID" is  what the  user requests  and need  not be
+          unique.  The file needs to be sorted.
+
+
+        * align (not implemented)
+            Like the  simpe mapping, but  the mapping is  dependent on
+            alignment information.   This depends on  the availability
+            of the  Bio::EnsEMBL::Mapper module  which is not  part of
+            Bioperl.
+
+          Format of map data file:
+
+            queryID,targetID,qAlignStart,tAlignStart,cigarLine
+
+          The  "queryID" is  what the  user requests  and need  not be
+          unique.  The cigar line is  on the Ensembl Cigar format, see
+          [5] (at  the end  of the  document).  The  file needs  to be
+          sorted.
