I think tree is now redundant ?

It was on my list of stuff to remove. I just forgot to create a ticket for it. As far as I can tell udev was the only package that used it, and the new build system doesn't have any test suites yet.

The book does not ask the reader to perform any tests. Running "make test-install" returns:

test -z "/etc/udev" || /bin/mkdir -p "/home/nate/src/udev-128/udev-test-install/etc/udev"
 /usr/bin/install -c -m 644 'udev.conf' '/home/nate/src/udev-128/udev-test-install/etc/udev/udev.conf'
make[3]: Leaving directory `/home/nate/src/udev-128'
make[2]: Leaving directory `/home/nate/src/udev-128'
make[1]: Leaving directory `/home/nate/src/udev-128'
tree /home/nate/src/udev-128/udev-test-install/
make: tree: Command not found
make: *** [test-install] Error 127

The code from Makefile

716 test-install:
717         rm -rf $(PWD)/udev-test-install/
718         make DESTDIR=$(PWD)/udev-test-install install
719         tree $(PWD)/udev-test-install/

Tree was not installed on my system but we do not run any tests so in this sense Tree has become redundant. If you'd like me to remove it from the book just assign ticket to me.

This is the output once tree is installed. At present Tree is redundant so I think it should either be removed from the book, OR udev's "make test-install" should be added to the udev final page if the reader wants to run the test.
