            5 Configuration parameters
            6 ========================
            7 
            8 Every parameter corresponds to a command-line option; some options map to a combination of
            9 parameters.
           10 
           11 There are five kinds of options and parameters:
           12 
           13 #. Strings (mostly file names),
           14 #. Scalars (a number representing a physical quantify, usually with units),
           15 #. Integers (an integer number, usually corresponding to a count),
           16 #. Flags (True/False, on/off, yes/no),
           17 #. Keywords (one of a given set of strings).
           18 
           19 Each parameter can be set using the command-line option consisting of a dash followed by
           20 the parameter name. For example,
           21 
           22 .. code-block:: none
           23 
           24    -constants.standard_gravity 10
           25 
           26 sets the acceleration due to gravity (parameter :config:`constants.standard_gravity`) to
           27 `10`. Options listed below are *shortcuts*, added for convenience.
           28 
           29 The following are equivalent and choose the temperature-based (as opposed to
           30 enthalpy-based) energy balance model:
           31 
           32 .. code-block:: none
           33 
           34    -energy.temperature_based
           35    -energy.temperature_based on
           36    -energy.temperature_based yes
           37    -energy.temperature_based true
           38    -energy.temperature_based True
           39 
           40 The following are also equivalent: they disable updating geometry by performing a step of
           41 the mass-continuity equation:
           42 
           43 .. code-block:: none
           44 
           45    -geometry.update.enabled off
           46    -geometry.update.enabled no
           47    -geometry.update.enabled false
           48    -geometry.update.enabled False
           49    -no_geometry.update.enabled
           50 
           51 The ``-no_`` prefix is still supported for compatibility with older scripts, but will be
           52 removed in a later PISM version.
