#   scheduling.cf - Command Execution Scheduling
#
#   NOTE: Commands can be executed based on any class expression.
#         Examples include execution of other commands (sequencing), 
#         time, OS, hostname or the outcome of another promise.
#         If a shell wrapper is not needed, removing it will increase
#         security and performance.
