# Configuration Definition Data
#
# Contains the defines for options: which commands the option can/cannot be specified, for which commands it is required, default
# settings, types, ranges, whether the option is negatable, whether it has dependencies, etc. The initial section is the global
# section meaning the defines defined there apply to all commands listed for the option.
#
# CFGDEF_INHERIT:
#     Inherit all definitions for the referenced option.  Any definitions can be overridden.
#
# CFGDEF_COMMAND:
#     List of commands the option can be used with this option.  An empty hash signifies that the command does not deviate from the
#     option defaults.  Otherwise, overrides can be specified.
#
# NOTE: If the option (A) has a dependency on another option (B) then the CFGCMD_ must also be specified in the other option
#         (B), else it will still error on the option (A).
#
# CFGDEF_REQUIRED:
#   In global section:
#       true - if the option does not have a default, then setting CFGDEF_REQUIRED in the global section means all commands
#              listed in CFGDEF_COMMAND require the user to set it.
#       false - no commands listed require it as an option but it can be set. This can be overridden for individual commands by
#               setting CFGDEF_REQUIRED in the CFGDEF_COMMAND section.
#   In CFGDEF_COMMAND section:
#       true - the option must be set somehow for the command, either by default (CFGDEF_DEFAULT) or by the user.
#           &CFGCMD_CHECK =>
#           {
#               &CFGDEF_REQUIRED => true
#           },
#       false - mainly used for overriding the CFGDEF_REQUIRED in the global section.
#
# CFGDEF_DEFAULT:
#   Sets a default for the option for all commands if listed in the global section, or for specific commands if listed in the
#   CFGDEF_COMMAND section. All boolean types require a default.
#
# CFGDEF_NEGATE:
#   The option can be negated with "no" e.g. --no-compress.  This applies to options that are only valid on the command line (i.e.
#   no config section defined) and if not specifically defined, the default is false.  All config file boolean options are
#   automatically negatable.
#
# CFGDEF_RESET:
#   The option can be reset to default even if the default is undefined.
#
# CFGDEF_DEPEND:
#   Specify the dependencies this option has on another option. All commands listed for this option must also be listed in the
#   dependent option(s).
#   CFGDEF_DEPEND_LIST further defines the allowable settings for the depended option.
#
# CFGDEF_ALLOW_LIST:
#   Lists the allowable settings for the option.
#
# CFGDEF_INTERNAL:
#   Option is used by the command internally but is not exposed in the documentation.  This is useful for commands that need to know
#   where they are running by looking at other options in the config.  Also good for test options.
