Enabling or disabling settings
If you have an unmodified dtx.ini file, the default value of the settings is listed on the commented-out line. To change the setting, first uncomment the line and then change the value.
A commented-out line is indicated by a semicolon (;) in front of the line. Uncommenting a line without changing the value does not change anything. Therefore, the following two lines are equal:
KeepDB=0
;KeepDB=0
