Clarify the specification of the renameTo method to say that its operation is
inherently system-dependent and that, in particular, it may or may not be
atomic and it may or may not succeed if a file or directory already exists
under the target name. -- mr@eng 8/18/1998
From a licensee :
# I think in the short term it would be good to add to the spec and javadoc
# output for renameTo, a note warning users of the difference between the
# unix and Win32 platforms.
# Would this be possible?
