config.cf Format

The format of "config.cf" is "variable = value syntax". If plural values are required, space or "\n\s" is a separator.

variable = value

valiable = value1 value2 value3

variable = value1
           value2
           value3

The syntax of files with the suffix .cf e.g. /etc/fml/main.cf , default_config.cf, is same.

$variable at the right hand is expanded. For example,

a = value1
b = $a/value2

is expanded to

a = value1
b = value1/value2

.

The variable expansion is done at the last. So, the following definitions

a = value1
b = $a/value2/$c
c = value3
a = value4

are expaned to

b = valu4/value2/value3

since the last $a overwrites the previous one.
