+The AmbientTalk/2 interpreter is written in pure Java and requires a regular J2SE Java Virtual Machine supporting version 1.3 or higher.
 == Installation and Usage ==
-To run the interactive shell, it suffices to launch the included **iat** shell script. IAT is a simple read-eval-print loop: statements are typed at the command line, evaluated and the result is printed to standard output. Note that the log and error traces are piped to the console.

 For an overview of the iat shell options, execute:
 <code>iat --help</code>
-<note>We advise you to add **iat** to the **$PATH** environment variable, such that **iat** can be invoked from any directory. Note also that **iat** assumes that the **java** executable is available on the **$PATH**</note>
+The system library shipped with the build can be found in the ''at/'' directory. It includes, among others, some demo applications and additional language constructs (most notably future-type asynchronous message sends). Also, the file ''at/init/init.at'' is loaded by default in each actor created at runtime to intialize that actor's global scope.
