cleanup SVN-files

I copied folder from SVN. And it include svn-files. I deleted it with follow script:

import os

from subprocess import call

d = os.walk$'my directory with SVN-tails'$

for i in d:

print i # about folder

if i $$0$$ $$-4:$$ == '.svn':

print i $$0$$

# delete SVN-files

call$['rm', '-R', i[0]]$
