 On the criteria for ordering
 ==============================
-
-I was confused by the documentation for sort's "-d" flag. This confusion
-relates to GNU coreutil's locale-specific sort. [^]
-
-Below I discuss sort order differences between different implementations
-of sort and of sh "*" for my particular environments.
-
-Sorting with sort
-------------
-Consider the following two sort commands.
-
-    printf '@ b\n- d\n? a\n~ c\n! e\n' | sort
-    printf '@ b\n- d\n? a\n~ c\n! e\n' | sort -d
-
-With BusyBox v1.23.2 on NixOS 15.09, the first of these commands returns
-ASCIIbetical order,
-
-    ! e
-    - d
-    ? a
-    @ b
-    ~ c
-
-and the second returns dictionary order.
-
-    ? a
-    @ b
-    ~ c
-    - d
-    ! e
-
-With GNU coreutils version 8.24 on NixOS, both commands return
-dictionary order. The same is true for GNU coreutils version 8.23 on
-Debian Wheezy.
-
-    ? a
-    @ b
-    ~ c
-    - d
-    ! e
-
-IEEE Std 1003.1, 2013 Edition [^^] specifies that the "-d" flag should
-enable dictionary order. All of these versions of sort have clear
-documentation about the order that should be returned when the "-d" flag
-is set, (See --help, man, or info.) and the implementations match the
-documentation as far as I can tell.
-
-I have found no explicit documentation from any relevant source as to
-what the default sort order should be. On the other hand, they all
-suggest that "-d" produces an order different from the default order.
-
-In GNU coreutils 8.24, for example, "-d" is a direction to "consider
-only blanks and alphanumeric characters". It lacks any mention that the
-"-d" flag has no effect or that it is the default. Furthermore, on my
-first reading, I took it to mean that the default is to consider all
-characters and that "-d" limits the considered characters to blanks and
-alphanumeric characters.

-Running in multiple environments
------------------------------------
-Setup for other environments includes the following.
-
-* Installing packages
-* `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.
