        <title>Build script structure</title>
        <para>A build script is made up of zero or more statements and script blocks. Statements can include method calls,
            property assignments, and local variable definitions. A script block is a method call which takes a closure
            as a parameter. The closure is treated as a <firstterm>configuration closure</firstterm> which configures

An assignment statement may assign a single value to a single variable, or multiple values to a
