# 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 /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'.

#########################
## Syntax of this file ##
#########################
# - It is read by grepping
# That mean you can write everything you want to in it. Just, if you want a variable set
# in the launcher, follow this syntax:
#
# '<no space><name of the variable>=<value>'
#
# Every other lines are ignored, but I still mark my comments with '#'.
# - Don't quote the values. You can't even put $name parts, and ${name} parts :)
# - If you want a particular value to be different for a set of machines, write :
#
# '<no space><name of the variable>(<name of the machines>)=<value>'
#
# (name of the machine is: hostname.domainname if domainname is set.
# hostname if not)
# You can set the variable my_name, too, but only if hostname is broken, since
# it's an internal value, too.
#
# different machines can even share the same value. Example:
# sensor_cpu(fulbert,toto,gabuzomeu)=yes
#
#
# Values used:
# Here are the ones mandatory:
# part_to_run=list of the parts of nws to run on this host
# authorized part name are : "nameserver memory sensor forecaster"
# order is not important. I manage this :)
# skills=list of the skills of the server to manage
