Components specific to the page - How?

[Timbow]

Okay, so I make a page with the slug sheep
Then I make a component with the slug sidebar-sheep
Likewise I make a page with the slug goats
Then I make a component with the slug sidebar-goats

Then in my template I call the sidebar with something like
<?php get_component('sidebar-get_page_slug()'); ?>
But I have to do something with the brackets or quotes don't I?

I found Mvlcek's instructions here:
http://mvlcek.bplaced.net/how-to/sidebars/
but he has an if else thing (which is good) to use the default sidebar and he gets an i18n_component which I don't understand. also an extra .(full stop / period) .
