# This script is called as the last step of the installation of the
# package.  All the package's files are in place, dpkg has already done
# its automatic conffile handling, and all the packages we depend of
# are already fully installed and configured.
# 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>
#        * <deconfigured's-postinst> `abort-deconfigure' `in-favour'
#          <failed-install-package> <version> `removing'
#          <conflicting-package> <version>
# for details, see http://www.debian.org/doc/debian-policy/ or
# the debian-policy package
#
# 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'.

# The following idempotent stuff doesn't generally need protecting
# against being run in the abort-* cases.

# Install info files into the dir file
##: install-info --quiet --section "section pattern" "Section Title" \
##:              --description="Name of the document" /usr/info/${package_name}.info

	Please type the name of your organization as you want it to
	appear on the Organization line of outgoing articles/patches.
	This information is stored in the configuration file
	/etc/news/organization. (It is nice if this also specifies
	your location.  Your city name is probably sufficient if well
	known.) For example:

	    University of Southern North Dakota, Hoople
         type in "--none--" if you do not want to specify one.
         However, you shall be asked again on the next upgrade if
         /etc/news/organization does not exist.
