# Generic SSH target.  Don't rename this target to `ssh`, that name is too
# useful elsewhere (site specific) and would probably get overridden confusingly.
# This target requires many `SSH_*` environment variables to be passed in, but
# we do use a global (makefile) variable for SSH_OPTS.  Makefiles including this
# file may wish to override
#
# usage example: see main Makefile for demo

# 	$(call _announce_target, $@)
# 	$(eval SSH_CMD ?= ${SSH_CMD:-bash})
# 	@echo 'set SSH_CMD: ${SSH_CMD}'
