Instrumentation in Scripting Languages - Linux Embedded systems

The same theory used for Java instrumentation can be used for any language, the primary difference being that scripting languages don’t have C’s notion of preprocessing or Java’s compilation step to remove unwanted code. This has some advantages in that the instrumentation can be turned on in the field easily for debugging, but it has the disadvantage of consuming space with messages and other information that is essentially dead weight. Most systems that use scripting languages aren’t economizing for space and can afford the few extra KB of text.
