[Proj] Geotrans, PCTrans and cs2cs - different angle signs?

Hello List,

It came to my attention that 7-parameters values should be different for 
cs2cs and
programs like Geotrans  and PCTrans. It seems all 3 angles should have 
sign to match cs2cs results. Shifts stay the same, as well as scaling 
(well, for
geotrans it is not in ppm).  I wonder if it is something well known or 
am I missing

Thank you,
