My file content like this 

cell	AND2 {
area = 20
pin Z (
type = output
function = A.B
outpit_capacitance =  2 )
pin Z1 (
type = output
function = !(A.B)
output_capacitance =  2 )
pin A (
type = input
capacitance = 5
)
pin B (
type = input
capacitance = 6
)
}

cell	NAND2 {
area = 10
pin Z (
type = output
function = !(A.B)
output_capacitance =  2 )
pin A (
type = input
capacitance = 4
)
pin B (
type = input
capacitance = 4
)
}


and would like to write output in the format as given below:

cell AND2
area = 20
output
Z = A.B
Z1 = (!A.B)
input
A capacitance = 5
B capacitance = 6


cell NAND2
area = 10
output
Z = A.B
input
A capacitance = 4
B capacitance = 4
