 # Programmatic Code Manipulation
 
-In this article, we will present some code snippets that demonstrate how we can manipulate the source code (packages, classes, methods, variables, traits, pragmas, etc.) programmatically, without using the SystemBrowser. Those techniques can be very useful for reflective operations, code generation, testing, etc.

+This article explains only those operations that **modify** the code. We will write a separate article on **querrying code** (looking for method senders, class references, pragma usages, etc.).
