How to express 'svn add' in cfengine

[Andreas J. Koenig]

Does anybody have a compact/elegant way of doing 'svn add' in
cfengine? That is a command to be done only once per file per machine?

I'd like to maintain a list of files that should be added to
subversion. The preparations for subversion are already in place, the
missing piece is the infrastructure for 'add' on a single file.

Bonus point for a solution that helps me to do 'svn delete', too.

Thanks,
