  Introduction
    The =Uize.Build.FileBuilders.CompiledCss= module defines a file builder for CSS files compiled from =.csst= files.

    *DEVELOPERS:* `Chris van Rensburg`

    Functions defined in the file builder are called as instance methods on an instance of a subclass of the =Uize.Services.FileBuilderAdapter= class, so the functions can access instance methods implemented in this class.
