It should be possible to generate reports with text & translation statistics in batch mode. I'd expect an additional command line argument, e.g. /statistics. It'd be used together with /generate, /update, /batch and other commands.
It should create reports, similar to those generated by /report command, but - very important! - statistics reports should be programmatically readable, i.e. XML or JSON.
Content-wise, statistic reports should contain the same data as we can see in the Translation Statistics window (Statistics button in Home ribbon).
