        <title>Introduction</title>
        <para>This reference guide describes the various types which make up the Gradle build language, or DSL.</para>
    </section>

    <section>
        <title>Some basics</title>
        <para>There are a few basic concepts that you should understand, which will help you write Gradle scripts.</para>

        <para>First, Gradle scripts are <firstterm>configuration scripts</firstterm>. As the script executes, it
            configures an object of a particular type. For example, as a build script executes, it configures an
            object of type <apilink class="org.gradle.api.Project"/>. This object is called the <firstterm>delegate object</firstterm>
            of the script. The following table shows the delegate for each type of Gradle script.
        </para>

        <table>
            <title>Script delegates</title>
            <thead>
                <tr>
                    <td>Type of script</td>
                    <td>Delegates to instance of</td>
                </tr>
            </thead>
            <tr>
                <td>Build script</td>
                <td>
                    <apilink class="org.gradle.api.Project"/>
                </td>
            </tr>
            <tr>
                <td>Init script</td>
                <td>
                    <apilink class="org.gradle.api.invocation.Gradle"/>
                </td>
            </tr>
            <tr>
                <td>Settings script</td>
                <td>
                    <apilink class="org.gradle.api.initialization.Settings"/>
                </td>
            </tr>
        </table>

        <para>The properties and methods of the delegate object are available for you to use in the script.</para>

        <para>Second, each Gradle script implements the <apilink class="org.gradle.api.Script"/> interface. This
            interface defines a number of properties and methods which you can use in the script.
        </para>

      -
      - 1. Adding new types:
      - There are 2 ways to include a new types to this guide:
      -     * Types referenced by a property are automatically included, if there is a corresponding ${typename}.xml in the DSL source directory.
      -     * Types listed in one of the following tables are included. There must be a corresponding ${typename}.xml in the DSL source directory.
      -
      - 2. Adding new sections:
      - The section title should end with 'types' (see AssembleDslDocTask.mergeContent)
      -->

    <section>
        <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
            some delegate object as it executes. The top level script blocks are listed below.</para>
        <table>
            <title>Build script blocks</title>
            <tr>
                <td>allprojects</td>
            </tr>
            <tr>
                <td>artifacts</td>
            </tr>
            <tr>
                <td>buildscript</td>
            </tr>
            <tr>
                <td>configurations</td>
            </tr>
            <tr>
                <td>dependencies</td>
            </tr>
            <tr>
                <td>repositories</td>
            </tr>
            <tr>

            </tr>
            <tr>
                <td>publishing</td>
            </tr>
        </table>
        <para>A build script is also a Groovy script, and so can contain those elements allowed in a Groovy script,
            such as method definitions and class definitions.
