--- Generate DB restore script using SQL Backup
--- Author : Jerome Duquène
--- Last review : 2008/04/09
---
--- Description :
--- As first step, this script will create the procedure SYS_getDatabaseFileNames.
--- Then based on the configured value for the target server and the list of DB to restore
--- it will generate the restore script.
--- Finally it will remove the stored procedure.
--- This script works if the server name is 14 char long and if it exists a share called like 'Backups_XXXXX'
--- where XXXXX is last 5 characters of the servername
---
--- Usage :
--- Configure the data, log and index paths
--- Configure the list of DB to restore
--- Configure the backup date
--- Configure the backup instance name
--- Run this script on the source server
--- Run the output script on the target server
----------------------------------------------------
