Hi,

All vendors recommend that you use their tuned routines :-)

There's nothing wrong with that per se, but when it's not performance- 
sensitive we prefer not to rely on too many external libraries since  
it makes debugging a nightmare. Still, we will make sure it works as  
an option.


Cheers,

Erik
