+	<title>Description</title>
+	<para>This generic function implements the main part of the
+	  database type initialization performed by
+	  <function>initialize-database-type</function>.  After
+	  <function>initialize-database-type</function> has checked
+	  that the given database type has not been initialized
+	  before, as indicated by
+	  <symbol>*initialized-database-types*</symbol>, it will call
+	  this function with the database type as it's sole
+	  parameter.  Database back-ends are required to define a
+	  method on this generic function which is specialized via an
+	  eql-specializer to the keyword representing their database
+	  type.</para>
+	<para>Database back-ends shall indicate successful
+	  initialization by returning <symbol>t</symbol> from their
+	  method, and <symbol>nil</symbol> otherwise.  Methods for
+	  this generic function are allowed to signal errors of type
+	  <errortype>clsql-error</errortype> or subtypes thereof.
+	  They may also signal other types of conditions, if
+	  appropriate, but have to document this.</para>
