=head1 NAME

Module::Install::ExtraTests - contextual tests that the harness can ignore

=head1 VERSION

0.008

=head1 COMMANDS

This plugin adds one Module::Install command:

=head2 extra_tests

  extra_tests;

This declares that the test files found in the directory F<./xt> should be run
only in certain instances:

  ./xt/author  - run when the tests are being run in an author's working copy
  ./xt/smoke   - run when the dist is being smoked (AUTOMATED_TESTING=1)
  ./xt/release - run during "make disttest"

These directories are recurisvely scanned for *.t files.  If any directories or
files exist in F<./xt> that are not recognized, the Makefile.PL will die.

B<Achtung!>  This is pretty scary, experimental code, mostly because it relies
on the pretty scary, non-experimental-but-seriously-sketchy underlying
customization system for ExtUtils::MakeMaker.  I may remove this warning when
I've decided that this is stable enough, but until then:

  HIC SUNT DRACONES

=head1 AUTHOR TESTS

"Is this being run by an author?" is determined internally by Module::Install,
but at the time of the writing of this version it's determined by the existence
of a directory called F<.author> in F<./inc>.  (On VMS, it's F<_author>.)  This
directory is created when Module::Install's F<Makefile.PL> is run in a
directory where no F<./inc> directory exists.

=head1 BUGS

Please report any bugs or feature requests through the web interface at
L<http://rt.cpan.org>. I will be notified, and then you'll automatically be
notified of progress on your bug as I make changes.
