Disable FastJet banner
FastJet seems to print the following banner, which would be rather annoying if it comes from all 1000s of HLT2 instances.

/// A call to this function modifies the stream used to print
/// banners (by default cout). If a null pointer is passed, banner
/// printout is suppressed. This affects all banners, including
/// those from plugins.
///
/// Please note that if you distribute 3rd party code
/// that links with FastJet, that 3rd party code must not
/// use this call turn off the printing of FastJet banners
/// by default. This requirement reflects the spirit of
/// clause 2c of the GNU Public License (v2), under which
/// FastJet and its plugins are distributed.
static void set_fastjet_banner_stream(std::ostream * ostr) {_fastjet_banner_ostr = ostr;}We should see what exactly applies to LHCb. Worst case, we can only disable it online.
