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.
See my answer on so: http://stackoverflow.com/a/26718189/321013
