You could also do this.. Your text.conf:

---
A:
 - B
 - C
D:

And in your readin.pl:

#!/usr/bin/perl -w
use YAML;
use Smart::Comments '###';
my $data = YAML::LoadFile('text.conf');
### $data
[download]

Your output:

### $data: {
###          A => [
###                 'B',
###                 'C'
###               ],
###          D => [
###                 'E',
###                 'F'
###               ],
###          G => [
###                 'H',
###                 'I'
###               ]
###        }
