As you have seen, it's pretty easy to write Awasu plugins, whether they be channel plugins that dynamically generate a feed or application plugins that extend Awasu itself.
One of the key features of Awasu's plugin architecture is that not only can you write a plugin in any language you choose, you can also write it outside of Awasu in whatever development environment you may have. All you have to do is set up an INI file containing the appropriate parameters and pass it to your script as the command-line argument. Once everything is working, simply plug it in!
Finally, if you write a plugin that might be useful to others, please send it in and we'll put it up on the web site for everyone to use. Thanks!
