Open a shell.

Ensure that your CLASSPATH environment variable contains the base Java runtime package ($JDKHOME/jre/lib/rt.jar for JDK 1.4 or higher).

Change to the KODOHOME directory.

Type 'chmod a+x bin/*'. This will give you execute permissions on all packaged shell scripts.

Type 'source bin/envsetup' (On Windows with Cygwin, type 'source bin/cygsetup'). This will modify your CLASSPATH and PATH environment variables to add in the libraries in KODOHOME/lib and the executables in KODOHOME/bin.
