And one of these at least:
    --xml: It generates a XML dump. It retrieves full history of all pages (if you want only the current version use --xml --curonly)
           If you want filter by namespace, use the parameter --namespaces=0,1,2,3...
    --images: It generates an image dump

You can resume previous incomplete dumps:
    --resume: It resumes previous incomplete dump. When using --resume, --path is mandatory (path to directory where incomplete dump is).

You can exclude namespaces:
    --exnamespaces: Write the number of the namespaces you want to exclude, split by commas.

You can be nice with servers using a delay:
    --delay: It adds a delay (in seconds, adding 5 seconds between requests: --delay:5)

Write --help for help."""
