Actually they are set but only within the environment of the script 
itself. Unix scripts, unlike Windows batch files, cannot change the 
environment of their parent process. Once the script terminates, so does 
the shell running it and you're back with the environment you started 
with. However, this should not be a problem in your application, since 
you'll be starting up resin within your script and it will inherit the 
right environment. If you want to convince yourself of this, put an 
"env" command at the end of your script to print out the environment.
