 ==== Object Inspector ====
+The module ''/.at.support.inspector'' implements a graphical object inspector. The module requires ''java.awt'' and ''javax.swing'' support from the underlying JVM running AmbientTalk. To inspect an object ''o'', execute:
+<code>
+import /.at.support.inspector;
+inspect(o);
+</code>
+This will pop up a graphical inspector on the object, listing the object's fields and methods. The object's fields and methods can recursively be inspected through the graphical user interface of the object inspector.
 ==== Symbiosis Utilities ====
+The module ''/.at.support.symbiosis'' defines a number of utility functions with respect to the symbiosis with the JVM. It defines the following functions which can be used to quickly create a wrapped Java value of the given primitive type:
+<code>
+long(anAmbientTalkNumber) -> aJavaLong
+short(anAmbientTalkNumber) -> aJavaShort
+float(anAmbientTalkFraction) -> aJavaFloat
+byte(anAmbientTalkNumber) -> aJavaByte
+</code>
+The module also defines the following function:
+<code>
+cast: obj into: Interface
+</code>
+The ''Interface'' argument should be a Java class wrapper for an interface type. The function returns a Java proxy object implementing the given interface, wrapping the given AmbientTalk object. If this proxy is subsequently passed to Java code, it will hold that ''proxy instanceof Interface''.
