## This small script takes as first argument a test indicator
## and the rest of the arguments are a command to run, with its
## command-line arguments.
## The script runs the command and then if the first argument is
## (1) -any -- returns success, ignoring the exit code of the command
## (2) -z  -- returns success iff the exit code is non-zero
## (3) some integer literal -- return success iff the exit code 
##     matches the given integer
## (4) -skip -- does not run the command and just exits with success
