=head1 NAME

Dist::Zilla::Plugin::UseUnsafeInc - Indicates the value of PERL_USE_UNSAFE_INC to use during installation

=head1 VERSION

version 0.001

=head1 SYNOPSIS

In your F<dist.ini>:

    ; this distribution still requires . to be in @INC
    [UseUnsafeInc]
    dot_in_INC = 1

or:

    ; this distribution does not need . to be in @INC
    [UseUnsafeInc]
    dot_in_INC = 0

=head1 DESCRIPTION

=for Pod::Coverage metadata after_build before_release

This is a L<Dist::Zilla> plugin that populates the C<x_use_unsafe_inc> key in your distribution metadata. This
indicates to components of the toolchain that C<PERL_USE_UNSAFE_INC> should be set to a certain value during
installation and testing, overriding any previous setting e.g. from the environment or from other tools.

The environment variable is also set in L<Dist::Zilla> while building and testing the distribution, to ensure
that local testing behaves in an expected fashion.

Additionally, the release must be performed using a Perl version that supports C<PERL_USE_UNSAFE_INC>, to further
guarantee test integrity.

=head1 CONFIGURATION OPTIONS

=head2 C<use_unsafe_inc>

This configuration value must be set in your F<dist.ini>, to either 0 or 1.  C<PERL_USE_UNSAFE_INC> will be set to
the same value by tools that support it.

=head2 C<DZIL_ANY_PERL>

When this environment variable is true, the Perl version check at release time (see above) is skipped.
