+      <h1>UCD Writer</h1>
+      
+      The UCD Writer stores finite-element cell-connectivity data.
+      The UCD format is used by popular FEM simulation packages like
+      ABAQUS and by visualization systems like AVS and Explorer.  It
+      is also a useful format to store AMR data into for visualization
+      systems since virtually no visualization system understands
+      heirarchial grids.<p>
+
+	The writer API has a lot of <b>beginSomething()</b> and
+	<b>endSomething()</b> statements.  This is because there may
+	be several independent lists of nodes and cells at a given
+	timestep in a completely arbitrary UCD dataset.  This
+	interface allows this to be dealt with in pieces.<p>

+	<DT><i>constructor</i> <b>UCDwriter::UCDWriter(
+	    IObase &iofile,
+	    IObase::DataType defaultnodetype=IObase::Float32,
+	    IObase::DataType defaultcelltype=IObase::Int32
+	    )</b>
+	<DD>The <i>filehandle</i> is an already open IEEEIO or HDFIO
+	  file.  This initializes the reader and attaches it to that
+	  datafile. You can optionally set the datatype for the
+	  node/vertex coordinates and the cell indices.  Normally
+	  these would be Float32 and Int32 respectively. 
+	<DT><i>destructor</i> <b>UCDwriter::~UCDwriter()</b>
+	<DD>This flushes all of the necessary file buffers and
+	  destroys the UCDwriter object.
+	  The filehandle that the writer was bound to must be
+	  closed separately though.
