 --skip FOO     Do not test the FOO component.
 --only FOO     Do not test anything except the FOO component.
+--temp DIR     Install components and dependencies under DIR instead of
+               making a new temporary directory. Implies --leave-temp.
 --leave-temp   Do not remove GOPATH, virtualenv, and other temp dirs at exit.
-               Instead, show which directories were used this time so they
-               can be reused in subsequent invocations.
+               Instead, show the path to give as --temp to reuse them in
+               subsequent invocations.
 --skip-install Do not run any install steps. Just run tests.
                You should provide GOPATH, GEMHOME, and VENVDIR options
                from a previous invocation if you use this option.
