          "/git/": "weekly",
          "/":     "monthly"
        },
        priorities={

### TODO

-  big sites with count of pages more then 100K will use more then 100MB
   memory. Move queue and done lists into database. Write Queue and Done
   backend classes based on
-  Lists

-  SQLite database

-  Redis

-  Write api for extending by user backends

## Changelog

    - Input (`dict`): `{ url_regex: changefreq_value, url_regex: ... }`

- Add support for <priority> tags (XML)

    - Input (`dict`): `{ url_regex: priority_value, url_regex: ... }`

- Reduce default concurrent max tasks from `100` to `10`
