A setting represented by a boolean flag (false, unless set)
A setting represented by a string in a given set of choices,
(default unless set).

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.
A Setting that collects string-valued settings from an enumerated domain.
A Setting that collects string-valued settings from an enumerated domain.
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.
A setting that accumulates all strings supplied to it, until it encounters one starting with a '-'.
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.

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 the string
"all" can be used to represent all phases.

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

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).

Equivalent to x.hashCode except for boxed numeric types and null.
For numerics, it returns a hash value which is consistent
with value equality: if two value type instances compare
as true, then ## will produce the same hash value for each
of them.
For null returns a hashcode where null.hashCode throws a
NullPointerException.

Cast the receiver object to be of type T0.
Cast the receiver object to be of type T0.
Note that the success of a cast at runtime is modulo Scala's erasure semantics.
Therefore the expression 1.asInstanceOf[String] will throw a ClassCastException at
runtime, while the expression List(1).asInstanceOf[List[String]] will not.
In the latter example, because the type argument is erased as part of compilation it is
not possible to check whether the contents of the list are of the requested type.

The eq method implements an equivalence relation on
non-null instances of AnyRef, and has three additional properties:
x and y of type AnyRef, multiple invocations of
x.eq(y) consistently returns true or consistently returns false.x of type AnyRef, x.eq(null) and null.eq(x) returns false.null.eq(null) returns true. When overriding the equals or hashCode methods, it is important to ensure that their behavior is
consistent with reference equality. Therefore, if two objects are references to each other (o1 eq o2), they
should be equal to each other (o1 == o2) and they should hash to the same value (o1.hashCode == o2.hashCode).

Test whether the dynamic type of the receiver object is T0.
Test whether the dynamic type of the receiver object is T0.
Note that the result of the test is modulo Scala's erasure semantics.
Therefore the expression 1.isInstanceOf[String] will return false, while the
expression List(1).isInstanceOf[List[String]] will return true.
In the latter example, because the type argument is erased as part of compilation it is
not possible to check whether the contents of the list are of the specified type.

Iterates over the arguments applying them to settings where applicable.
Iterates over the arguments applying them to settings where applicable. Then verifies setting dependencies are met.
This temporarily takes a boolean indicating whether to keep processing if an argument is seen which is not a command line option. This is an expedience for the moment so that you can say
scalac -d /tmp foo.scala -optimise
while also allowing
scala Program opt opt
to get their arguments.
