[CM] snd svn at sourceforge

[bil at ccrma.Stanford.EDU]

sourceforge is ending its support of CVS, so (after screwing
up once or twice...) I have created what I think is a working
SVN repository there, accessible via:

svn checkout svn://svn.code.sf.net/p/snd/svn1/trunk snd

(There's a broken snd/svn directory -- I don't know how to delete it,
but use svn1, and the cvs directory now has only historical interest).

Now to figure out how to commit updates...
