This script dumps the wiki page database into an XML interchange wrapper
format for export or backup.

XML output is sent to stdout; progress reports are sent to stderr.

Usage: php dumpBackup.php <action> [<options>]
Actions:
  --full      Dump complete history of every page.
  --current   Includes only the latest revision of each page.

Options:
  --quiet     Don't dump status reports to stderr.
  --report=n  Report position and speed after every n pages processed.
              (Default: 100)
  --server=h  Force reading from MySQL server h
  --start=n   Start from page_id n
  --end=n     Stop before page_id n (exclusive)
  --skip-header Don't output the <mediawiki> header
  --skip-footer Don't output the </mediawiki> footer
  --stub      Don't perform old_text lookups; for 2-pass dump

Fancy stuff:
  --plugin=<class>[:<file>]   Load a dump plugin class
  --output=<type>:<file>      Begin a filtered output stream;
                              <type>s: file, gzip, bzip2, 7zip
  --filter=<type>[:<options>] Add a filter on an output branch
