For compatibility and reusability of your code, PSR1 recommends that a file should introduce either new symbols (like classes, functions, etc.) or have side-effects (like outputting something, or including other files), but not both at the same time. The first symbol is defined on line 30 and the first side effect is on line 28.

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

WARNING: this is not a full database dump! It is merely for public export
         of your wiki. For full backup, see our online help at:
