=head1 NAME

Acme::Pi - Mmm, pie

=head1 VERSION

version 3.14159265358979

=head1 SYNOPSIS

    use Acme::Pi;

    my $area = $Ï€ * $radius**2;
    my $volume = 4 * π / 3 * $radius**3;

=head1 DESCRIPTION

=for Pod::Coverage 𝝿 π

This distribution was created to celebrate L<Pi Day|http://www.piday.org/> 2014,
as well as to demonstrate yet another example of a pathological C<$VERSION>.

Additionally, it exports two variables: C<$π> and C<$𝝿>,
and two constants, C<π> and C<𝝿>, defined as:

    atan2(1,1) * 4;

This module also defines its own C<$VERSION> as a fixed-point value approximating
Ï€ (using as many digits as is supported on the local machine).
It is intended that version parsers in the toolchain (L<Module::Metadata>,
L<ExtUtils::MakeMaker>'s C<< MM->parse_version >>, L<Parse::PMFile>) should
be capable of statically parsing this package's C<$VERSION>.
