 It would be cool to run Nagios plugins with Urchin. This is already possible,
 actually, but it might be worth giving some special thought to it.

+Source setup and teardown
+--------------------
+If setup and teardown are sourced instead of executed, maybe we can more
+cleanly create and teardown temporary files.
+
+    (
+      . ./setup
+      ./$thetestfile
+      . ./teardown
+    )
+
+On the other hand, this could just be sourced explicitly in the test file,
+without the special setup and teardown feature.
+
+Run on a file
+----------------
+Presently you can run urchin only on a directory.
+It would be neat if you could run it on a file as well.
+
+This occurred to me when I wanted to run
+
+    urchin test/fast/Unit\ tests/nvm_ls_current
+
+on the nvm tests. I wound up running this instead.
+
+    urchin test/fast/Unit\ tests/ | grep nvm_ls_current
+
+The Molly guard would be assessed, and the corresponding setup, setup_dir,
+teardown, and teardown_dir files would be run in the appropriate order.
+
+Running automated tasks
+-------------------------
+Urchin might be appropriate for if you have lots of tasks that you want to run
+periodically; add an urchin call to your crontab, and call all of your other
+tasks with urchin. Here are some features that might make urchin better for
+this sort of thing.
+                                                      
+* Time how long each test/job takes
+* Optionally kill tests/jobs after a specific timeout threshold
+* Send output of different tests/jobs to different files for each file
