 # Script to test NSS SSL - distributed stresstest - this script needs to
 # source the regular ssl.sh (for shellfunctions, certs and variables
 # initialisation)
 # create certs
 # start server
 # start itself via rsh on different systems to connect back to the server
 #
 #
 # needs to work on all Unix and Windows platforms

 # special strings
