[boost] Adding a --log_level="message" runtime option to a Boost.test test-suite

Can anyone tell me how to add a --log_level="message" runtime option to a Boost.Test test-suite. Running using VS project I have a Custom Build Step command line "$(TargetDir)$(TargetName).exe" --log_level="message" I'd like to replicate this in a jamfile : ... test-suite "multiprecision EFX numerical test" : [ run numerical_test.cpp ] ; but adding --log_level="message" (and perhaps other Boost.test options as well). (I want this for all compilers of course, so placing in compile options doesn't seem right.) Suggestions most welcome. Thanks Paul --- Paul A.
