The Macintosh operating system (versions System 7.1 and later) has a system-level extension called AppleScript. AppleScript is an automation tool, and is a method by which you can control the behavior and functionality of specific programs. Application developers make their programs AppleScript-Savvy by adding an "AETE Resource." The AETE Resource for an application tells AppleScript what kinds of things it can do in that particular application.
There are three general levels of compatibility with Apple System resources like AppleScript: "Savvy," "Aware," and "Incompatible." If an application is described as AppleScript Savvy, it means that it has an "AETE Resource," which is the list of commands, or "Dictionary" for that application. It serves as the list of commands that AppleScript can execute in that program. If an application is described as AppleScript Aware, it means that it is fully compatible with AppleScript, and although it does not have an AETE Resource, it may support AppleScript or Apple events in a very limited way. If an application is described as being incompatible with AppleScript, it means that for some reason that program may exhibit crashes or other undesirable behavior when AppleScript is installed.
AppleScript-savvy applications like ClarisWorks 4.0 are described in three ways: "Scriptable," "Recordable," and "Attachable."  ClarisWorks 4.0 contains an AETE Resource, so it is AppleScript Savvy, but it is only Scriptable, meaning that its commands must be accessed through scripting applications like Frontier, AppleScript, or even FileMaker Pro. 
For an application to be Recordable, that application has to be able to send Apple events to describe what it's doing as it does things - those events can be stored by AppleScript as scripts, because AppleScript was able to "watch" them being done in the application where they were executed. Recordable applications are relatively uncommon due to the amount of programming that is required. Attachable applications  allow you to attach scripts to menu selections, buttons, or other controls within the Attachable application itself.
Here is how the ClarisWorks 4.0 event dictionary appears in the AppleScript Script Editor.
