trev - opening trace files (part of staden package)

       Trace files can be opened either on the command line or from within Trev. In both cases it is possible to
       open several traces at once. In this case trev will add Next File, Previous File and Goto File buttons to
       allow quick navigation between traces.  On the command line, this is simply done  by  specifying  several
       files.   With  the  "Open"  dialogue from within trev multiple files may be selected by dragging with the
       left mouse button or using shift+left button and control+left button  to  extend  regions  or  to  toggle
       loading of individual files.
