Manage schema.xml via Solrj?

[Bob Lawson]

I want to programmatically make changes to schema.xml using java to do it.  
Should I use Solrj to do this or is there a better way?  Can I use Solrj to 
make the rest calls that make up the schema API?  Whatever the answer, can 
anyone point me to an example showing how to do it?  Thanks!
