As asked on SO: 
http://stackoverflow.com/questions/26505229/how-to-log-boost-test-output-to-both-stdout-in-hrf-and-to-a-file-in-xml

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?

-----------
Rationale:

When running tests on or [Jenkins][4] server, the [xUnit plugin][5] 
[requires][6] the **log** XML output (as opposed to the *report* XML 
output -- `log_level` vs. `report_level`).

However, the in-progress log output (in HRF) is highly valuable *while* 
the tests are running on the server, to detect hanging tests or to a 
quick manual check of where the tests currently are. So I want an 
in-progress HRF log for the tests and at the end I need an XML file 
containing the `<TestLog>...</TestLog>` output of Boost.Test (not the 
`<TestResult>` output).

Do note that we run both unit as well as integration tests via 
Boost.Test, so some of them are quite long-running.
