DateTime::Format::Natural::Lang::EN - English language metadata

=head1 DESCRIPTION

C<DateTime::Format::Natural::Lang::EN> provides the english specific grammar
and variables. This class is loaded if the user either specifies the english
language or implicitly.

=head1 EXAMPLES

Below are some examples of natural language date/time input in english (be aware
that the parser does usually not distinguish between lower/upper case; furthermore,
many expressions allow for additional leading/trailing time and all times are
also parsable with precision in seconds):
