# Configuration options:

# * <tt>:in</tt> - An enumerable object of available items. This can be
|
|
# supplied as a proc, lambda or symbol which returns an enumerable. If the
|
|
# enumerable is a numerical range the test is performed with <tt>Range#cover?</tt>,
|
|
# otherwise with <tt>include?</tt>. When using a proc or lambda the instance
|
|
# under validation is passed as an argument.
|
|
# * <tt>:within</tt> - A synonym(or alias) for <tt>:in</tt>
|
|
# * <tt>:message</tt> - Specifies a custom error message (default is: "is
|
|
# not included in the list").

# There is also a list of default options supported by every validator:

# +:if+, +:unless+, +:on+, +:allow_nil+, +:allow_blank+, and +:strict+.
