Merge multiple text files line by line using ANT

How do I merge multiple text files into one file. I want to read text line by line from each file and then merged text into the final output file. Sample text in my files are:

File 1 : 

  aaa  
  bbb  
  ccc

File 2 : 

  ddd  
  eee  
  fff

File 3 : 

  ggg  
  hhh  
  iii

Expected Output: 

  aaa  -->from file 1
  ddd  -->from file 2
  ggg  -->from file 3
  bbb  
  eee  
  hhh  
  ccc  
  fff  
  iii

I have tried the target below 

<target name="mergeappvars" >  
    <concat destfile="${out.dir}/ApplicationGV.txt" force="no">  
        <fileset dir="${work.dir}/application"  
     includes="*.txt"/>  
    </concat>  
</target>

My logic is appending one file after another and I got the output as

aaa
bbb
ccc
ddd
eee
fff
ggg
hhh
iii
