You can now write plugins for FLIR and use them in your own projects.
Download the latest version of FLIR and look in the plugins directory.
Two plugins are now included with facelift that you can use as the basis for creating your own plugins. (Better documentation is coming...)
If you want to use a plugin, simply assign the FLIRStyle Object's mode to the name of the plugin.
For example, a plugin included with the latest version of FLIR is FancyFonts.php. So, to use this plugin, you would assign the mode to fancyfonts. If the plugin requires any options to be set you can simply set them inside the FLIRStyle Object like so... FLIRStyle.whatever the plugin option.
