+##
+############################################################################
+## History
+##
+## 1.0 first start of the program
+## 1.1 some changes from monty and after that
+## initial release in mysql 3.22.10 (nov 1998)
+## 1.2 begin screen now in a loop + quit is using 0 instead of 9
+## after ideas of Paul DuBois.
+## 1.2a Add Grant, References, Index and Alter privilege handling (Monty)
+## 1.3 Applied patch provided by Martin Mokrejs <mmokrejs@natur.cuni.cz>
+## (General code cleanup, use the GRANT statement instead of updating
+## the privilege tables directly, added option to revoke privileges)
+## 1.4 Remove option 6 which attempted to erroneously grant global privileges

+ The permission setter for MariaDB.
+ version: $version
+
+ made by: Luuk de Boer <luuk\@wxs.nl>
+----------------------------------------------------------------------
+
+The permission setter is a little program which can help you add users
+or databases or change passwords in MariaDB. Keep in mind that we don't
+check permissions which already been set in MariaDB. So if you can't
+connect to MariaDB using the permission you just added, take a look at
+the permissions which have already been set in MariaDB.
+
+The permission setter first reads your .my.cnf file in your Home
+directory if it exists.
+
+Options for the permission setter:
+
+--help : print this help message and exit.
+
+The options shown below are used for making the connection to the MariaDB
+server. Keep in mind that the permissions for the user specified via
+these options must be sufficient to add users / create databases / set
+passwords.
+
+--user : is the username to connect with.
+--password : the password of the username.
+--host : the host to connect to.
+--socket : the socket to connect to.
+--port : the port number of the host to connect to.
+
+If you don't give a password and no password is set in your .my.cnf
+file, then the permission setter will ask for a password.
