# postinst script for erlang-base-hipe
#
# see: dh_installdeb(1)
set -e
# summary of how this script can be called:
# * <postinst> configure <most-recently-configured-version>
# * <old-postinst> abort-upgrade <new-version>
# * <conflictor's-postinst> abort-remove in-favour <package> <new-version>
# * <postinst> abort-remove
# * <deconfigured's-postinst> abort-deconfigure in-favour <failed-install-package> <version> \
# removing <conflicting-package> <version>
# for details, see /usr/doc/packaging-manual/
#
# quoting from the policy:
# Any necessary prompting should almost always be confined to the
# post-installation script, and should be protected with a conditional
# so that unnecessary prompting doesn't happen if a package's
# installation fails and the <postinst> is called with abort-upgrade,
# abort-remove or abort-deconfigure.
