One thing you could do, as I did for the 'gcore' command, is to
make the official command eg. "static-trace", and then make strace
be an abbreviation for it.  Just a small thing to draw attention
to the distinction between this and the other strace.

Similarly, "fast-trace" could be that official command, and ftrace
an abbreviation.
