Using Ant to rebuild runtime css files

When building applications or tools that need to be skinnable at runtime, using Ant to rebuild your runtime CSS files is a huge timesaver.

Naturally, you need to install Ant in Flex Builder 3 first.

As a sidenote, when building skinnable apps, a CSS might not be sufficient to create highly graphical skins, for example when you want to make a completely skinnable mediaplayer in Flex (having skinning options comparable to the Winamp player for instance). This can be achieved by loading a (transparent) SWF on top of your application and have your player communicate with the "dynamically loaded view" via a common Interface for user control and visualization. This works well, but if anyone knows of a better way to build a skinnable mediaplayer, please let me know...
