# usage: tarscp <host> [remote-dir [local-file ...]]
#
# Uses tar, bzip2, and ssh to transfer files to a remote host. It's
# faster than scp -Cr with many small files.
#
# If no files are specified the current directory is copied to
# remote-dir on host. If remote-dir is not specified the name of the
# current directory is used as the remote directory.
#
# You may want to use gzip instead of bzip2 on slower machines,
# bzip2's runtime can be longer than transfer times with fast
# connections.
