I would like to have an easy-to-use stand-alone parameter file parser. Presumably, this utility would be build as a Cactus utility in the flesh. I would take a parameter file as input, and would output parameter values as output (probably either in some ASCII format or in xml). It would also know about default values of parameters.
This utility could answer the following questions: - which parameters are set in a parameter file? - what is the value of parameter X (which may have its default value)? - list all parameters that are set in the parameter file - list all parameters and their values
Bonus points if it also knows about which thorns are active; this is non-trivial since some thorns are activated automatically.
