      This text is a tutorial for people interested in using our
      Java$^{\rm (TM)}$-based implementation of Guaraná, a reflective architecture
      that aims at flexibility, security and reuse of meta-level code.  It
      shows what kind of operations can be intercepted with Guaraná and how
      meta-objects can monitor and modify base-level behavior.  It also
      introduces composition of meta-objects, and discusses dynamic
      reconfiguration and management of meta-configurations.  Several tricks
      and internal details of the implementation are exposed, through the
      use of numerous examples and detailed explanations.
