TileStache Cache tiles to Digital Ocean Space

Using Tilestache, i can configure tiles cache directory to Amazon S3 Bucket

http://tilestache.org/doc/TileStache.S3.html

  "cache": {
    "name": "S3",
    "bucket": "<bucket name>",
    "access": "<access key>",
    "secret": "<secret key>"
  }

But i have a digital ocean space, where my rest of data is hosted. How can i configure it to Digital Ocean space ?
