As asked on SO: http://stackoverflow.com/questions/26505229/how-to-log-boost-test-output-to-...

I would like to enable logging of Boost.Test output to *both* the stdout/sterr and to a logfile.

However, I would also like to have the stdout logging be in HumanReadableFormat and only the file output be in XML format.

Generating a report file seems to be addressed [here][1]. ([official docs][2])

Choosing the format can be done in [various ways][3], but it seems one is stuck with either HRF or XML?

I managed to get this working.
