### Set store-auth-creds to 'no' to avoid storing any subversion ### credentials in the auth/ area of your config directory. ### It defaults to 'yes'. Note that this option only prevents ### saving of *new* credentials; it doesn't invalidate existing ### caches. (To do that, remove the cache files by hand.) store-auth-creds = no即可
