*******************************************
* Welcome to the Koha Installation Guide  *
*******************************************

This installer will guide you through the process of installing Koha.
It is not a completely automated installation, but a guide for further 
information please read the documentation or visit the Koha website at
http://www.koha.org

To successfully use Koha you need some additional software:

* A webserver (It was built to work with Apache, but there is no reason
it should not work with any other webserver). 
 
* Mysql (You could intead use postgres, or another sql based database) 

* Perl

Are you ready to go through the installation process now? (Y/[N]):

my $answer = <STDIN>;
chomp $answer;

if ($answer eq "Y" || $answer eq "y") {
	print "Beginning setup... \n";
    } else {
    print qq|
When you are ready to complete the installation just run this installer again.

    exit;

#KOHA conf
#
print qq|
Koha uses a small configuration file that is usually placed in your
/etc/ files directory (note: if you wish to place the koha.conf in 
another location you will need to manually edit additional files).

We will help you to now create your koha.conf file, once this file 
has been created, please copy it to your destination folder
(note: this may need to be done by your systems administrator).

*******************************************
* Koha Installation Guide - Continued     *
*******************************************

In order to finish the installation of Koha, there is still a couple 
of steps that you will need to complete.

  * Setup mysql
	1. Create a new mysql database called for example Koha
	   From command line: mysqladmin -uroot -ppassword create Koha 

	2. Set up a koha user and password in mysql
           Log in to mysql: mysql -uroot -ppassword 

	   To create a user called "koha" who has full administrative 
	   rights to the "Koha" database when authenticating from 
	   "localhost", enter the following on mysql command line: 

	    grant all privileges on Koha.* to koha\@localhost identified by 'kohapassword'\;

	   Press ENTER, and if you see no errors then enter \q to quit mysql.


	3. Use the mysql script to create the tables
	   mysql -uusername -ppassword Koha < koha.mysql 

	4. Update your database tables
	   perl updatedatabase -I /pathtoC4 


  * Koha.conf
	1. Copy Koha.conf to /etc/
	   If you wish to locate the file in another location please read 
	   the INSTALL and Hints files.

#
# It is completed
#
print "\nCongratulations ... your Koha installation is complete!\n";
print "\nYou will need to restart your webserver before using Koha!\n";
