## 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 <[e-mail]>
##     (General code cleanup, use the GRANT statement instead of updating
##     the privilege tables directly, added option to revoke privileges)
