Automating CSS in a plugin

Hi, I'm looking for advice on how best to implement a plugin that
contains some CSS. I would like the CSS to be automatically added to any
layout so that the only action I need to perform is installation of the
plugin.

Is this possible?

The reason for this is that the plugin includes some view partials and I
want to provide default stylesheets so the partial's contents look
reasonable by default.

If application-specific styling is then required the styles would be
customised by overriding in a controller's style sheet outside the
plugin.

I assume I will need a stylesheets folder in the plugin and have the
plugin installer copy any stylesheets into the application's public
folder. What I don't know is how I can have that stylesheet applied
automatically. They way I do this now is to use a helper in the layout
to include the stylesheet but I'd like to avoid that.

I have used the Styler plugin to help manage css before and it's quite
good. I could customise that to include plugin css in its search.

But is there a better way to achieve this?

Thanks!

Would anyone be able to help with my query?

I'd say monkey patch the view helpers to inject your own code (css, js,
whatever) in it.
