Maybe I'll finish my git-depot proof of concept script someday. Here's the configuration reader method I use (please note git-depot doesn't use repositories -- yet):

sub readConfig
{
	my $self = shift;
	my ($cfg, @cfg, $cat, $key, $val);

	$cfg = Git::command(qw/config -z -l/);
	@cfg = split(/\000/m, $cfg);
	%{$self->{cfg}} = ();
	foreach (@cfg) {
		if (($cat, $key, $val) = (/\A(\S+)\.(\S+)[\n\r]+^(.+)\Z/ms)) {
			next unless $cat eq 'depot';
			$self->{cfg}->{$key} = $val;
		}
	}
	return 1;
}

Works like a charm.
