# by the startup.sh, shutdown.sh files).  This file is also invoked
# by the deploy.sh file.
#
# It is preferable (to simplify migration to future Geronimo releases) 
# to set any environment variables you need in the setenv.sh file
# rather than modifying Geronimo's script files.  See the documentation
# in the geronimo.sh file for further information.

# (Based upon Apache Tomcat 5.5.12's setclasspath.sh)
