+=head1 WHERE'S THE REST?
+
+A drink leaked in my bag on the way back from LPW. My laptop is finally
+alive again though so I'll try and turn my slides into a vague attempt
+at documentation while I'm traveling to/from christmas things.
+
+=head1 Example
+
+$ cat Takfile
+package Tak::MyScript;
+
+use strict;
+use warnings;
+
+use Tak::Takfile;
+use Tak::ObjectClient;
+use lib "./lib";
+
+sub each_host {
+    my ($self, $remote) = @_;
+
+    my $oc = Tak::ObjectClient->new(remote => $remote);
+    my $name = $oc->new_object('My::Hostname');
+    print "Connected to hostname: " . $name . "\n";
+    }
+

+

+
+$cat ./lib/My/Hostname
+package My::Hostname;
