7.  class IntSetting extends Setting

   A setting represented by an integer.

8.  abstract class MultiChoiceEnumeration extends Enumeration

   Each MultiChoiceSetting takes a MultiChoiceEnumeration as domain.

   Each MultiChoiceSetting takes a MultiChoiceEnumeration as domain. The enumeration may use the Choice class to define values, or simply use the default `Value` constructor:

   object SettingDomain extends MultiChoiceEnumeration { val arg1, arg2 = Value }

   Or

   object SettingDomain extends MultiChoiceEnumeration { val arg1 = Choice("arg1", "help") val arg2 = Choice("arg2", "help") }

   Choices with a non-empty `expandsTo` enable other options. Note that expanding choices are not present in the multiChoiceSetting.value set, only their expansion.

9.  class MultiChoiceSetting[E <: MultiChoiceEnumeration] extends Setting with Clearable

   A Setting that collects string-valued settings from an enumerated domain.

   A Setting that collects string-valued settings from an enumerated domain.

   - These choices can be turned on or off: "-option:on,-off"
   - If an option is set both on and off, then the option is on
   - The choice "_" enables all choices that have not been explicitly disabled

   Arguments can be provided in colonated or non-colonated mode, i.e. "-option a b" or "-option:a,b". Note that arguments starting with a "-" can only be provided in colonated mode, otherwise they are interpreted as a new option.

   In non-colonated mode, the setting stops consuming arguments at the first non-choice, i.e. "-option a b c" only consumes "a" and "b" if "c" is not a valid choice.

10.  class MultiStringSetting extends Setting with Clearable

    A setting that accumulates all strings supplied to it, until it encounters one starting with a '-'.

11.  class OutputDirs extends AnyRef

    A class for holding mappings from source directories to their output location.

    A class for holding mappings from source directories to their output location. This functionality can be accessed only programmatically. The command line compiler uses a single output location, but tools may use this functionality to set output location per source directory.

12.  class OutputSetting extends StringSetting

    Set the output directory for all sources.

13.  class PathSetting extends StringSetting
14.  class PhasesSetting extends Setting with Clearable

    A setting represented by a list of strings which should be prefixes of phase names.

    A setting represented by a list of strings which should be prefixes of phase names. This is not checked here, however. Alternatively, underscore can be used to indicate all phases.

15.  class PrefixSetting extends Setting

    A special setting for accumulating arguments like -Dfoo=bar.

17.  class ScalaVersionSetting extends Setting

    A setting represented by a Scala version.

    A setting represented by a Scala version. The `initial` value is used if the setting is not specified. The `default` value is used if the option is specified without argument (e.g., `-Xmigration`).

18.  abstract class Setting extends AbsSetting with SettingValue

    A base class for settings of all types.

    A base class for settings of all types. Subclasses each define a `value` field of the appropriate type.
