#
# REDIRECT	-	Redirect all output to a logfile
# CHECKOUT	-	Fill the sandbox with a fresh cvs checkout
# BUILD		-	Build everything
# GENERATE	-	Generate a new world
# SERVERSTART	-	Start the server
# TESTSCRIPT	-	Run the testscript
# SERVERSTOP	-	Stop the server if it was started by this script
# CLEANUP	-	Remove the contents of the sandbox

# For some reason, solaris sh exits as soon as both stderr and stdout
# are redirected to file at the exec, so if we run on solaris, use ksh
