=head1 NAME
dh_installzopeinstance - install a zope instance into package build directories
=cut
use strict;
use Debian::Debhelper::Dh_Lib;
=head1 SYNOPSIS
B<dh_installzopeinstance> [S<I<debhelper options>>] [B<-n>] [S<I<instance name>>]
=head1 DESCRIPTION
dh_installzopeinstance is a debhelper program that is responsible for installing
zope instances into package build directories.
The argument is interpreted as zope instance and will be created within the
first package dh_installzopeinstance is told to act on. By default, this is
the first binary package in debian/control, but if you use B<-p>, B<-i>,
or B<-a> flags, it will be the first package specified by those flags.
dh_installzopeinstance automatically install debian/dzinstance if it exists.
If dh_installzopeinstance is acting on multiple packages, debian/dzinstance file will
be installed into the first package. Use debian/package.dzinstance for
different binary packages.
The substitution variable zope:Depends is replaced by a list of the available
zope versions.
=head1 OPTIONS
=over 4
=item B<-n>, B<--noscripts>
Do not modify postinst/prerm scripts.
=item I<instance name>
This parameter will be considered as an instance name which will
be installed into the first package acted on.
=back
=head1 EXAMPLES
This is an example of a debian/package.dzinstance file:
Package: plone-site
ZopeVersion: 2.9
Name: plone-site
Addon-Mode: manual
Addon-Technique: tree-linked
Restart-Policy: end
Products: CMFPlone
Skeleton: /usr/lib/zope2.9/skel-with-magic
The Products field specify a list of comma separated products that will
be automatically installed into the instance. Obviously, it has no sense
if the Addon-Mode field contains 'all'.
The optional Skeleton field specifies a path which is used as skeleton for
the new zope instance.
=head1 NOTES
Note that this command is not idempotent. "dh_clean B<-k>" should be called
between invocations of this command. Otherwise, it may cause multiple
instances of the same text to be added to maintainer scripts.
