 * There are two ways of running tests. As a "user", if psutil is already
   installed and you just want to test it works::
 
-    python -m psutil.tests --install-deps  # install test deps
     python -m psutil.tests
 
   As a "developer", if you have a copy of the source code and you wish to hack
   on psutil::
 
-    make setup-dev-env  # install test deps (+ other things)

     make test
 
 * To run tests on all supported Python versions install tox
