This script reads pages from an XML file as produced from Special:Export or
dumpBackup.php, and saves them into the current wiki.
Compressed XML files may be read directly:
.gz $gz
.bz2 $bz2
.7z (if 7za executable is in PATH)
Note that for very large data sets, importDump.php may be slow; there are
alternate methods which can be much faster for full site restoration:
