# The first command line argument is a non-empty relative path
# specifying the "from" directory.
# Each other argument is a file name not containing / and
# names a file in the current directory.
#
# For each of these files, we create in the "from" directory a link
# of the same name pointing to the local file.
#
# We assume that the directory structure is a tree, i.e. that it does
# not contain symbolic links and that the parent of / is never referenced.
# Apart from this, this script should be able to handle even the most
# pathological cases.
