How to Install AspectJ
=======================

1. Download a stable version of AspectJ distribution from
   http://www.eclipse.org/aspectj, e.g., aspectj-1.6.10.jar for Java
   1.6 and aspectj-1.5.4.jar for Java 1.5.

   If you use Eclipse, you may want to install AJDT, an Eclipse plugin
   containing the AspectJ compiler, instead. For this, refer to
   www.eclipse.org/ajdt.

2. To install the jar file, say, aspectj-1.6.10.jar, do the following
   on the command prompt:

   java -jar aspectj-1.6.10.jar

   You will see an installation window; simply follow the
   instructions. It will ask you where you want to install AspectJ
   and where your current JDK installation is located.

3. Finalize the installation by:
 
   (1) adding INSTALL_DIR/lib/aspectjrt.jar to your CLASSPATH and
   (2) modifying your PATH to include INSTALL_DIR/bin,

   where INSTALL_DIR is the directory where you installed AspectJ.
   The AspectJ compiler, ajc, and other tools such as ajdoc and
   ajbrowser are found in the directory INSTALL_DIR/bin.

   On Windows, right-click on "My Computer", click "Properties", and
   select the "Advanced" tab. Then, click the "Environment Variables"
   button. From there you can edit or create environment variables
   such as CLASSPATH and PATH. On Unix systems, you may need to modify
   the login or shell startup files appropriate for your shell, e.g.,
   .bashrc and .cshrc.
