+=head1 EXAMPLE
+
+Here's C<modrm>, a little utility to cleanly remove an installed module.
+
+    #!/usr/local/bin/perl -w
+
+    use strict;
+    use IO::Dir;
+    use ExtUtils::Packlist;
+    use ExtUtils::Installed;
+
+    sub emptydir($) {
+	my ($dir) = @_;
+	my $dh = IO::Dir->new($dir) || return(0);
+	my @count = $dh->read();
+	$dh->close();
+	return(@count == 2 ? 1 : 0);
+    }
+
+    # Find all the installed packages
+    print("Finding all installed modules...\n");
+    my $installed = ExtUtils::Installed->new();
+
+    foreach my $module (grep(!/^Perl$/, $installed->modules())) {
+       my $version = $installed->version($module) || "???";
+       print("Found module $module Version $version\n");
+       print("Do you want to delete $module? [n] ");
+       my $r = <STDIN>; chomp($r);
+       if ($r && $r =~ /^y/i) {
+	  # Remove all the files
+	  foreach my $file (sort($installed->files($module))) {
+	     print("rm $file\n");
+	     unlink($file);
+	  }
+	  my $pf = $installed->packlist($module)->packlist_file();
+	  print("rm $pf\n");
+	  unlink($pf);
+	  foreach my $dir (sort($installed->directory_tree($module))) {
