Override configuration resources
Options to override resources defined in the GAS configuration file can be implemented at the command line when starting the dispatcher.
Dispatcher override option (-E)
The dispatcher has an option that allows you to override a resource defined in the configuration file (as.xcf) at the command line. For example:
httpdispatch -E res.dvm.wa=$FGLDIR/bin/myrun
The value set by the override option (-E) takes precedence over the value
set by the configuration file.
