This class provides you with a boolean object which can accept many forms of input and output itself in many forms. The idea is for this class to hold only the boolean value in a pure form (either 0 or 1) and be able to do boolean arithmetic on that value while the input (at construction or at arithmetic time) and the output could have many forms like y/n, 0/1, yes/no, true/false, t/f etc... The versions currently supported are :

	new($)
	new_value($$)
	set_value($$)
	get_value($)
	new_version($$$)
	set_version($$$)
	get_version($$)
	not($)
	TEST($)

new($)

This is a constructor for the Meta::Types::Bool object. By default the value of it is 1 (true).

new_value($$)

This is a value constructor for the Meta::Types::Bool object. If the value you passed evaluates to true then the type will have a 1 (true) value.

set_value($$)

Give this method a value and it will set the internal value of the boolean according to whether your value evaluates to true.

get_value($)

This method retrieves the current value of the boolean.

new_version($$$)

Pass a value and a version to this constructor and it will give you an object with the internal value stored accordingly.

set_version($$$)

Pass a version and value to this method and it will set the internal boolean value accordingly.

get_version($$)

Pass a version to this method and you will get the boolean value converted to this version.

not($)

This method will perform a boolean NOT operation on the value stored.

TEST($)

This is a testing suite for the Meta::Types::Bool module. This test is should be run by a higher level management system at integration or release time or just as a regular routine to check that all is well. Currently this test just produces an object with one version and prints it out with another.
