There is something I don't understand in chapter 21 "Slony-I Administration
Scripts" from Slony 2.0.2 Documentation. I have listed my questions within
the content at below. 


21.1. altperl Scripts

There is a set of scripts to simplify administeration of set of Slony-I
instances. The scripts support having arbitrary numbers of nodes. They may
be installed as part of the installation process:
Where are the scripts that its talking about?
./configure --with-perltools

This will produce a number of scripts with the prefix slonik_. They
eliminate tedium by always referring to a central configuration file for the
details of your site configuration. A documented sample of this file is
provided in altperl/slon_tools.conf-sample. where is this "altperl" it is
talking about? and this slon_tools.conf file is used to set what? Most also
include some command line help with the "--help" option, making them easier
to learn and use.

Most generate Slonik scripts that are printed to STDOUT. At one time, the
commands were passed directly to slonik for execution. Unfortunately, this
turned out to be a pretty large calibre "foot gun", as minor typos on the
command line led, on a couple of occasions, to pretty calamitous actions.
The savvy administrator should review the script before piping it to slonik.
