Application
    foamList

Description
    Print the table of contents of selectable switches, classes etc. in the
    OpenFOAM libraries

Usage
    \b foamList [OPTION]

    Options:
      - \par -switches
        Print the DebugSwitches, InfoSwitches and OptimisationSwitches

      - \par -registeredSwitches
        Print the registered DebugSwitches, InfoSwitches and
        OptimisationSwitches supporting run-time modification

      - \par -unset
        print switches declared in libraries but not set in etc/controlDict
