Also dump the requested file descriptor activity in any new child
processes that are created.

tty with echo, you might want this.

Display a version string.

FILES
/proc/*/fd

Not used but useful for the user to look at to get good file descriptor
numbers.

The following diagnostics may be issued on stderr:
- Error attaching to pid ...
-
An unknown error occurred while attempted to attach to a process.. you
may need to be root.
BUGS

dies.
