deleting managed content using svn

[Robert Huff]

	I have a system that uses svn to track src+ports+doc.
	For reasons I won't get into, I want to scrub all svn-managed
material under src in preparation for grabbing a completely clean
copy.
	Neither on-system documentation nor the deeper documentation
listed therein show how to do this.  Or at least not in a way my
brain is currently processing.  :-)
	Is there a better way than "rm -rf"?

	Respectfully,
