+=head1 NAME
+
+complete-run.pl - Run the i3 testsuite
+
+=head1 SYNOPSIS
+
+complete-run.pl [files...]
+
+=head1 EXAMPLE
+
+To run the whole testsuite on a reasonable number of Xdummy instances (your
+running X11 will not be touched), run:
+ ./complete-run.pl
+
+To run only a specific test (useful when developing a new feature), run:
+ ./complete-run t/100-fullscreen.t
+
+=head1 OPTIONS
+
+=over 8
+
+=item B<--display>
+
+Specifies which X11 display should be used. Can be specified multiple times and
+will parallelize the tests:
+
+ # Run tests on the second X server
+ ./complete-run.pl -d :1
+
+ # Run four tests in parallel on some Xdummy servers
+ ./complete-run.pl -d :1,:2,:3,:4
+
+Note that it is not necessary to specify this anymore. If omitted,
+complete-run.pl will start (num_cores * 2) Xdummy instances.
+
+=item B<--valgrind>
+
+Runs i3 under valgrind to find memory problems. The output will be available in
+C<latest/valgrind-for-$test.log>.
+
+=item B<--strace>
+
+Runs i3 under strace to trace system calls. The output will be available in
+C<latest/strace-for-$test.log>.
+
+=item B<--coverage-testing>
+
+Exits i3 cleanly (instead of kill -9) to make coverage testing work properly.
+
+=item B<--parallel>
+
+Number of Xdummy instances to start (if you don’t want to start num_cores * 2
+instances for some reason).
+
+ # Run all tests on a single Xdummy instance
+ ./complete-run.pl -p 1
