# importrel
#
# Shell script to import a release in the 
# the BaBar code system from another site
#
# Bob Jacobsen Mar 1995
#
# (Test releases are not yet supported)
#
# Options:
#   -p  Reference a production release. (required)
#   -a  don't copy the contents of the bin, lib, tmp subdirectories
#        (i.e. allow user to use individual importarch commands)
#   -g  use gtar instead if tar (useful for AIX4.1)
# Arguments:
#   <release name>       Number of release
#
# Note that the directory structure is assumed to exist.
# 
# Note that the BFDISTr environment variable should
# contain an access route (similar to CVSROOTr), for
# example "jake@unixhub.slac.stanford.edu:/nfs/juno/u5/dist"
#
# It would be very useful to only tar and transmit "interesting"
# subdirectories based on which BFARCH values a site wants to
# receive.
