# Kauri Runtime startup script for use during Kauri development
#  meaning: there is no KAURI_HOME, Kauri artifacts are in dev's local Maven repo
#

# You can use the following environment variables to customize the startup
#
# KAURI_CLI_CLASSPATH
#    additional entries to be added to the classpath
#
# KAURI_JAVA_ARGS
#    additional options to be passed to the java executable
#
# KAURI_DEBUG_ARGS
#    can be used to define alternative Java debug arguments
#
# KAURI_DEBUG_SUSPEND_ARGS
#    can be used to define alternative Java debug arguments for suspended mode
#

#
# Disclaimer: this script is based on stuff from Apache Cocoon's 'cocoon.sh' script
