      To test the results, issue: <command>make -k check</command>. Note that you
      must run the tests from a session with X Window Display capability (i.e.,
      not a text-based terminal/console) as the tests attempt to open an X
      window, and the tests can take an excessively long time. Using an X
      Window, the tests should take less than 0.1 SBU. One test,
      aliasfilescheck.sh, is known to fail.
