=head1 NAME

SmokeRunner::Multi::TestSet::SVN - Represents a set of test based on an SVN checkout

=head1 VERSION

version 0.21

=head1 SYNOPSIS

  my $set = SmokeRunner::Multi::TestSet->new( set_dir => 'path/to/set' );

=head1 DESCRIPTION

This test set subclass will be used when a test set is an SVN
checkout, which is determined by looking for a F<.svn> directory in
the set directory.

=head1 METHODS

This class provides the following methods:

=head2 $set->last_mod_time()

This subclass will run F<svn info> on the checkout's URI to get the
last modified time for the whole set, not just test files.

=head2 $set->update_files()

This calls F<svn up> to update the test set.
