    perl Makefile.PL PREFIX=~
    make test
    make install UNINST=1

You can install into the same location with Module::Build using this:

    perl Build.PL --prefix ~
    ./Build test
    ./Build install --uninst 1

=head3 C<prefix> vs C<install_base>

The behavior of C<prefix> is complicated and depends on
how your Perl is configured.  The resulting installation locations
will vary from machine to machine and even different installations of
Perl on the same machine.  Because of this, it's difficult to document
where C<prefix> will place your modules.

In contrast, C<install_base> has predictable, easy to explain
installation locations.  Now that C<Module::Build> and C<MakeMaker> both
have C<install_base> there is little reason to use C<prefix> other
than to preserve your existing installation locations.  If you are
starting a fresh Perl installation we encourage you to use
C<install_base>.  If you have an existing installation installed via
C<prefix>, consider moving it to an installation structure matching
C<install_base> and using that instead.


=head2 Running a single test file

C<Module::Build> supports running a single test, which enables you to
track down errors more quickly.  Use the following format:

  ./Build test --test_files t/mytest.t

In addition, you may want to run the test in verbose mode to get more
informative output:

  ./Build test --test_files t/mytest.t --verbose 1

I run this so frequently that I define the following shell alias:

  alias t './Build test --verbose 1 --test_files'

So then I can just execute C<t t/mytest.t> to run a single test.


=head1 ADVANCED RECIPES


=head2 Making a CPAN.pm-compatible distribution

New versions of CPAN.pm understand how to use a F<Build.PL> script,
but old versions don't.  If authors want to help users who have old
versions, some form of F<Makefile.PL> should be supplied.  The easiest
way to accomplish this is to use the C<create_makefile_pl> parameter to
C<< Module::Build->new() >> in the C<Build.PL> script, which can
create various flavors of F<Makefile.PL> during the C<dist> action.

As a best practice, we recommend using the "traditional" style of
F<Makefile.PL> unless your distribution has needs that can't be
accomplished that way.

The C<Module::Build::Compat> module, which is part of
C<Module::Build>'s distribution, is responsible for creating these
F<Makefile.PL>s.  Please see L<Module::Build::Compat> for the details.


=head2 Changing the order of the build process

The C<build_elements> property specifies the steps C<Module::Build>
will take when building a distribution.  To change the build order,
change the order of the entries in that property:

  # Process pod files first
  my @e = @{$build->build_elements};
  my ($i) = grep {$e[$_] eq 'pod'} 0..$#e;
  unshift @e, splice @e, $i, 1;

Currently, C<build_elements> has the following default value:

  [qw( PL support pm xs pod script )]

Do take care when altering this property, since there may be
non-obvious (and non-documented!) ordering dependencies in the
C<Module::Build> code.


=head2 Adding new file types to the build process

Sometimes you might have extra types of files that you want to install
alongside the standard types like F<.pm> and F<.pod> files.  For
instance, you might have a F<Bar.dat> file containing some data
related to the C<Foo::Bar> module and you'd like for it to end up as
F<Foo/Bar.dat> somewhere in perl's C<@INC> path so C<Foo::Bar> can
access it easily at runtime.  The following code from a sample
C<Build.PL> file demonstrates how to accomplish this:

  use Module::Build;
  my $build = Module::Build->new
    (
     module_name => 'Foo::Bar',
     ...other stuff here...
    );
  $build->add_build_element('dat');
  $build->create_build_script;

This will find all F<.dat> files in the F<lib/> directory, copy them
to the F<blib/lib/> directory during the C<build> action, and install
them during the C<install> action.

If your extra files aren't located in the C<lib/> directory in your
distribution, you can explicitly say where they are, just as you'd do
with F<.pm> or F<.pod> files:

  use Module::Build;
  my $build = new Module::Build
    (
     module_name => 'Foo::Bar',
     dat_files => {'some/dir/Bar.dat' => 'lib/Foo/Bar.dat'},
