# Issue595
#
# A test for running "darcs get" when the parent directory has restrictive
# permissions.  The bug is that darcs trys to "chdir" to the current directory
# using the full path.  The permissions on the parent directory prevent this
# from working, even though the current repo and the remote have sufficient
# permissions.
#
# The real-world case where this would happen would be a web-server with
# restrictive permissions on "/home", with a user running darcs within that.
