When I used a script file including my Buckminster commands instead of entering the commands directly into the Buckminster command text area variable substitution does not appear to be respected.

Thus, if I use something like ${WORKSPACE}/pathToSomething in the command enterted directly in the Buckminster text area , then the ${WORKSPACE} variable is substituted correctly to the Hudson workspace for the current job. However, if I use the same variable within my Buckminster script file, then a blank string is substituted instead when the command is run.
