Do you want a Unix-style distribution?
In this distribution mode files go into different directories according
to Unix conventions. A "racket-uninstall" script will be generated
to be used when you want to remove the installation. If you say 'no',
the whole Racket directory is kept in a single installation directory
(movable and erasable), possibly with external links into it -- this is
often more convenient, especially if you want to install multiple
versions or keep it in your home directory.
*** This is a nightly build: such a unix-style distribution is *not*
*** recommended because it cannot be used to install multiple versions.

Where do you want to install the "racket-@N" directory tree?
1 - /usr/racket-@N [default]
2 - /usr/local/racket-@N
3 - ~/racket-@N (@|testdir|/racket-@N)
4 - ./racket-@N (here)
Or enter a different "racket" directory to install in.

Done.

If you want to install new system links within the "bin" and
"man" subdirectories of a common directory prefix (for example,
"/usr/local") then enter the prefix of an existing directory
that you want to use. This might overwrite existing symlinks,
but not files.
