-[ REPLACE THIS...
+You can feed the ->create method with a recursive datastructure and have the related records
+created.  Unfortunately you cannot do a similar thing with update_or_create - this module
+tries to fill that void. 
 
-  The README is used to introduce the module and provide instructions on
-  how to install the module, any machine dependencies it may have (for
-  example C compilers and installed libraries) and any other information
-  that should be understood before the module is installed.
-
-  A README file is required for CPAN modules since CPAN extracts the
-  README file from a module distribution so that people browsing the
-  archive can use it get an idea of the modules uses. It is usually a
-  good idea to provide version information here so that people can
-  decide whether fixes for the module are worth downloading.

 =head1 DESCRIPTION
-This is the first release - so treat it as experimental.
+This is still experimental. I've added a functional interface so that it can be used 
+in Form Processors and not require modification of the model.
 
 You can feed the ->create method with a recursive datastructure and have the related records
 created.  Unfortunately you cannot do a similar thing with update_or_create - this module
