+\033[1mUsage:\033[m
+
+   $(basename $0) [OPTION [OPTION ..
+
+
+\033[1mDescription\033[m
+
+   Script restores a database from a database dump file.
+
+
+\033[1mNotice\033[m
+
+   This script was created to restore large databases. The recovery of such databases often takes 
+   a lot of time (often several hours). For a more performant but above all faster recovery, 
+   global variables are changed for the recovery time. This requires extensive rights on the 
+   database server. Please take this into account when specifying the MySQL login information.
+
+
+\033[1mOptions\033[m
+
+   -b
+      Sets batch mode to true - no interaction will be made.
+
+   -c <database credentials>
+      A string containing credentials to establish a database connection. This character string 
+      can consist of username and password, but also of login information stored in the file system 
+      or the database itself.
+
+      Example:
+
+         -c "u root -p '<password>'"
+         -c "--login-path=local"
+         -c "--defaults-file=/usr/local/mysql/sys-maint.cnf"
+         -c "-u root -S /run/mysqld/mysqld.sock"
+
+      If this Parameter is omitted, the script tries to detect the right credentials.
+      
+
+   -d <db-name>
+      The name of the database to restore.
+
+   -f <dqpn-to-db-dump-file>
+      Full qualified Path Name (FQPN) to the Dump file from which the database is to be restored.
+
+   -h
+      Prints this help.
+
+
+   -s <db-server>
+      The database server to restore the database to. It is possible to enter an IP address or a host name.
+
+
