 * `touch .zshrc`
 * Copy urchin and tests
 
+
+Fixtures
+------------
+I want to change the way that fixtures are done.
+
+Instead of using setup, teardown, &c., use ordinary programs from within
+your tests. For example.
+
+    # tests/.fixtures/tmp-dir
+    tmp=$(mktemp -d)
+    cd $tmp
+    @$
+    code=$?
+    cd /
+    rm -Rf $tmp
+    exit $code
+
+    # tests/blah
+    ../.fixtures/tmp-dir 'blah blah blah'
+
+It's best if I can wrap a bunch of commands in braces or paratheses
+rather than just one command. Is there a nice way to do that?
+
+Once I have this new way, I guess I might as well keep the old way.
+I think the setup, teardown thing can be easier if you only have simple
+fixtures. And since I'm going to keep it, I'm going to add another one.
+
+* setup_dir runs once for the present directory.
+* setup_children runs once for each child.
+* setup_file runs once for each file descendent.
+
+The present `setup` is renamed to `setup_children`, and the new
+`setup_file` runs on each file (not directory) that is a child,
+grandchild, great-grandchild, and so on.
+
+Dependency checking
+----------------------
+You might want to skip tests based on dependencies. Currently you can
+conditionally skip tests one at a time by exiting with code 3. I want to
+be able to skip an entire directory.
+
+So we add a new magic file called `dep`. If it exists, it is run before
+everything else in the directory.
+
+* If it exits with code 0, tests continue as if dep did not exist.
+* If it exits with code 3, all tests in the directory are marked as
+  skipped.
+* If it exits with code 1, all tests in the directory are marked as
+  failed. To make the implementation easier, I'll probably treat the
+  directory as a single test in this case.
+
+A note on magic files
+-------------------------
+It is nice to have access to things like setup and dep (magic files)
+once in a while, but you need to be doing rather substantial testing
+before they make your test suite simpler; the documentation should
+strongly recommend writing your tests without magic files and then
+refactoring and only then considering moving things to magic files.
+
+Remote testing
+----------------
+In order to test Urchin across multiple operating systems, I have
+already added tests in Urchin's test suite that run Urchin tests in
+remote servers. I would like to move this to Urchin itself so that
+Urchin can test other things on remote servers.
+
+Urchin's output presently looks like this.
+
+    Cycling with the following shells: sh bash dash mksh zsh 
+    Running tests at 2016-04-07T12:33:49
+
+    Flags/
+    > --timeout output
+    . bash (0 seconds)
+    . dash (0 seconds)
+    . mksh (0 seconds)
+    . sh (0 seconds)
+    . zsh (0 seconds)
+
+    Done, took 1 second.
+    5 tests passed.
+    0 tests skipped.
+    0 tests failed.
+
+After the change, the output should look like this.
+
+    Cycling with the following shells: sh dash mksh
+    Running tests at 2016-04-07T12:33:49
+

+    . sh on localhost (0 seconds)
+    . sh on localhost:8080 (0 seconds)
+    . sh on tlevine@hpux.polarhome.com (0 seconds)
+
+    Done, took 1 second.
+    8 tests passed.
+    0 tests skipped.
+    0 tests failed.
+
+This is just how the output should look; the tests run in whatever order
+makes sense.
