--api or --index: URL to api.php or to index.php, one of them. If wiki has api.php, please, use --api instead of --index. Examples: --api=http://archiveteam.org/api.php or --index=http://archiveteam.org/index.php
And one of these at least:
--xml: it generates a XML dump. It retrieves full history of pages located in namespace = 0 (articles)
If you want more namespaces, use the parameter --namespaces=0,1,2,3... or --namespaces=all
If you want only the current versions of articles (not the full history), use --curonly option too
--images: it generates an image dump
--logs: it generates a log 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 time sleep (in seconds, adding 5 seconds between requests: --delay:5)
Write --help for help."""
