# This is a default configuration file which will operate correctly in

# uncomplicated installations. Please see the manual for a complete list

# of all the runtime configuration options that can be included in a

# configuration file.
|
|
|
|
|
|
# This file is divided into several parts, all but the last of which are
|
|
# terminated by a line containing the word "end". The parts must appear
|
|
