Matthew Flatt 2b9c0c4689 avoid using directory-exists? as part of a contract 
Although a `directory-exists?` check is useful for providing better
error messages, it's fundentally a race condition, since an external
process can always remove a directory between the check and a use of
the directory. Because of that limitation of `directory-exists?`, we
normally avoid making it part of a contract. This commit adjust
937aa3cdb1 to follow that convention while preserving the helpful
check and documentation improvements.

This is the source code for the core of Racket. See "INSTALL.txt" for full information on building Racket.

To build the full Racket distribution from this repository, run make in the top-level directory. To build minimal Racket, run make base.

The rest of the Racket distribution source code is in other repositories, mostly under the Racket GitHub organization.
