+=head1 NAME
+
+FS::Conf - Read access to Freeside configuration values
+
+=head1 SYNOPSIS
+
+  use FS::Conf;
+
+  $conf = new FS::Conf;
+  $conf = new FS::Conf "/non/standard/config/directory";
+
+  $dir = $conf->dir;
+
+  $value = $conf->config('key');
+  @list  = $conf->config('key');
+  $bool  = $conf->exists('key');
+
+=head1 DESCRIPTION
+
+Read access to Freeside configuration values.  Keys currently map to filenames,
+but this may change in the future.
+
+=head1 METHODS
+
+=over 4
+
+=item new [ DIRECTORY ]
+
+Create a new configuration object.  Optionally, a non-default directory may
+be specified.
+
+=cut
+
+sub new {
+  my($proto,$dir) = @_;
+  my($class) = ref($proto) || $proto;
+  my($self) = { 'dir' => $dir || $default_dir } ;
+  bless ($self, $class);
+}
+
+=item dir
+
+Returns the directory.
+
+=cut
+
+sub dir {
+  my($self) = @_;
+  $self->{dir};
+}
+
+=item config 
+
+Returns the configuration value or values (depending on context) for key.
+
+=cut
+
+sub config {
+  my($self,$file)=@_;
+  my($dir)=$self->dir;
+  my $fh = new IO::File "<$dir/$file" or return;
+  if ( wantarray ) {
+    map {
+      /^(.*)$/ or die "Illegal line in $dir/$file:\n$_\n";
+      $1;
+    } <$fh>;
+  } else {
+    <$fh> =~ /^(.*)$/ or die "Illegal line in $dir/$file:\n$_\n";
+    $1;
+  }
+}
+
+=item exists
+
+Returns true if the specified key exists, even if the corresponding value
+is undefined.
+
+=cut
+
+sub exists {
+  my($self,$file)=@_;
+  my($dir) = $self->dir;
+  -e "$dir/$file";
+}
+
+=back
+
+=head1 BUGS
+
+The option to specify a non-default directory should probably be removed.
+
+Write access (with locking) should be implemented.
+
+=head1 SEE ALSO
+
+config.html from the base documentation contains a list of configuration files.
