If the builder is in the same package as the record and the record
is package-private, make the builder package-private too.

+
+# Customizing RecordBuilder
+
+RecordBuilder can be customized in a number of ways. The types of customizations will change over time. See
+[@RecordBuilder.Options](record-builder-core/src/main/java/io/soabase/recordbuilder/core/RecordBuilder.java)
+for the current set of customizations and their default values. 
+
+You can:
+
+- [Customize an entire build](#customize-an-entire-build) - all uses of `@RecordBuilder` in your project
+- [Customize a single record](#customize-a-single-record) annotated with `@RecordBuilder`
+- [Create a custom annotation](#create-a-custom-annotation) that specifies your options and use that instead of `@RecordBuilder`
+
+## Customize an entire build
+
+To customize an entire build, use javac's annotation processor options via `-A` on the command line.
+The options available are the same as the attributes in [@RecordBuilder.Options](record-builder-core/src/main/java/io/soabase/recordbuilder/core/RecordBuilder.java).
+i.e. to disable "prefixing enclosing class names", compile with:
+
+```shell
+javac -AprefixEnclosingClassNames=false ...
+```
+
+_Note: use a separate `-A` for each option._
+
+#### Maven
+
+If you are using Maven, specify the options in the compiler plugin:
+
+```xml
+<plugin>
+    <groupId>org.apache.maven.plugins</groupId>
+    <artifactId>maven-compiler-plugin</artifactId>
+    <version>${maven-compiler-plugin-version}</version>
+    <configuration>
+        <compilerArgs>
+            <arg>-AprefixEnclosingClassNames=false</arg>
+            <arg>-AfileComment="something different"</arg>
+        </compilerArgs>
+    </configuration>
+</plugin>
+```
+
+#### Gradle
+
+For Gradle, specify the options:
+
+```groovy
+compilerArgs.addAll(['-AprefixEnclosingClassNames=false', '-AfileComment="something different"'])
+```
+
+## Customize a single record
+
+To customize a single record, add `@RecordBuilder.Options` in addition to
+`@RecordBuilder`.
+
+E.g.
+
+```java
+@RecordBuilder.Options(withClassName = "Wither")
+@RecordBuilder
+public record MyRecord(String s){}
+```
+
+## Create a custom annotation
+
+Using `@RecordBuilder.Template` you can create your own RecordBuilder annotation
+that uses the set of options you want. E.g. to create a custom annotation that
+uses an alternate file comment and an alternate With classname:
+
+```java
+@RecordBuilder.Template(options = @RecordBuilder.Options(
+        fileComment = "MyCo license",
+        withClassName = "Wither"
+))
+@Retention(RetentionPolicy.SOURCE)
+@Target(ElementType.TYPE)
+@Inherited
+public @interface MyCoRecordBuilder {
+}
+```
+
+Now, you can use `@MyCoRecordBuilder` instead of `@RecordBuilder` and the record
+will be built with options as specified.
