Thanks to artist for the help to my earlier problem, but I am now stumped again. The grammar worked just fine, but now I need to figure out the actions to create the hash structure that gets passed back (actually a reference to a hash). My test script looks like: 
#!/opt/perl5/bin/perl -w
use strict;
use Parse::RecDescent;
use vars qw ($grammar);
$::RD_HINT=1;
use Data::Dumper;

$grammar = q(
        file: section(s)
        section: header assign(s?)
        header:   '[' /\w+/ ']' { $item[2] }
        assign:   pair comment(?)
        pair:     /\w+/ '=' /\w+/  { [$item[1],$item[3]] }
        comment:  /[\#\;]/ /.*/  { $item[2] }
        );
my $parser= Parse::RecDescent->new($grammar);

my $text;

{
 $/=undef;
 $text=<DATA>;
}
my $tree=$parser->file($text);

print Dumper($tree);

__DATA__
[Section1]
key1=value1
key2=value2   #Comment2
key3=value3

[Section2]
key4=value4
key5=value5
key6=value6   ;Comment 6

The end result that I would like to achieve, when I dump it out with Data::Dumper, would be:
$VAR1 = bless( {
                 'Section2' => {
                                 'key4' => 'value4',
                                 'key5' => 'value5',
                                 'key6' => [
                                             'value6',
                                             'Comment 6'
                                           ]
                               },
                 'INI' => 'test.ini',
                 'Section1' => {
                                 'key1' => 'value1',
                                 'key2' => [
                                             'value2',
                                             'Comment2'
                                           ],
                                 'key3' => 'value3'
                               }
               }, 'Config::Yacp' );

As you can see from my test script, I've got the values I need for the header, pair, and comments, but I'm missing the file and section. When I run the test script, it basically prints out an AoAoA, with only the comments inside. All I need is just a pointer in the general direction
