+=head1 DESCRIPTION
+
+I list here some of the most important methods in C<Module::Build>.
+Normally you won't need to deal with these methods unless you want to
+subclass C<Module::Build>.  But since one of the reasons I created
+this module in the first place was so that subclassing is possible
+(and easy), I will certainly write more docs as the interface
+stabilizes.
+
+
+=head2 CONSTRUCTORS
+
+=over 4
+
+=item current()
+
+[version 0.20]
+
+This method returns a reasonable facsimile of the currently-executing
+C<Module::Build> object representing the current build.  You can use
+this object to query its L</notes()> method, inquire about installed
+modules, and so on.  This is a great way to share information between
+different parts of your build process.  For instance, you can ask
+the user a question during C<perl Build.PL>, then use their answer
+during a regression test:
+
+  # In Build.PL:
+  my $color = $build->prompt("What is your favorite color?");
+  $build->notes(color => $color);
+
+  # In t/colortest.t:
+  use Module::Build;
+  my $build = Module::Build->current;
+  my $color = $build->notes('color');
+  ...
+
+The way the C<current()> method is currently implemented, there may be
+slight differences between the C<$build> object in Build.PL and the
+one in C<t/colortest.t>.  It is our goal to minimize these differences
+in future releases of Module::Build, so please report any anomalies
+you find.
+
+One important caveat: in its current implementation, C<current()> will
+B<NOT> work correctly if you have changed out of the directory that
+C<Module::Build> was invoked from.
+
+=item new()
+
+[version 0.03]
+
+Creates a new Module::Build object.  Arguments to the new() method are
+listed below.  Most arguments are optional, but you must provide
+either the L</module_name> argument, or L</dist_name> and one of
+L</dist_version> or L</dist_version_from>.  In other words, you must
+provide enough information to determine both a distribution name and
+version.
+
+
+=over 4
+
+=item add_to_cleanup
+
+[version 0.19]
+
+An array reference of files to be cleaned up when the C<clean> action
+is performed. See also the L<add_to_cleanup()|/"add_to_cleanup(@files)">
+method.
+
+=item auto_configure_requires
+
+[version 0.34]
+
+This parameter determines whether Module::Build will add itself
+automatically to configure_requires (and build_requires) if Module::Build
+is not already there.  The required version will be the last 'major' release,
+as defined by the decimal version truncated to two decimal places (e.g. 0.34,
+instead of 0.3402).  The default value is true.
+
+=item auto_features
+
+[version 0.26]
+
+This parameter supports the setting of features (see
+L</feature($name)>) automatically based on a set of prerequisites.  For
+instance, for a module that could optionally use either MySQL or
+PostgreSQL databases, you might use C<auto_features> like this:
+
+  my $build = Module::Build->new
+    (
+     ...other stuff here...
+     auto_features => {
+       pg_support    => {
+                         description => "Interface with Postgres databases",
+                         requires    => { 'DBD::Pg' => 23.3,
+                                          'DateTime::Format::Pg' => 0 },
+                        },
+       mysql_support => {
+                         description => "Interface with MySQL databases",
+                         requires    => { 'DBD::mysql' => 17.9,
+                                          'DateTime::Format::MySQL' => 0 },
+                        },
+     }
+    );
+
+For each feature named, the required prerequisites will be checked, and
+if there are no failures, the feature will be enabled (set to C<1>).
+Otherwise the failures will be displayed to the user and the feature
+will be disabled (set to C<0>).
+
+See the documentation for L</requires> for the details of how
+requirements can be specified.
+
+=item autosplit
+
+[version 0.04]
+
+An optional C<autosplit> argument specifies a file which should be run
+through the L<AutoSplit::autosplit()|AutoSplit/autosplit> function.
+If multiple files should be split, the argument may be given as an
+array of the files to split.
+
+In general I don't consider autosplitting a great idea, because it's
+not always clear that autosplitting achieves its intended performance
+benefits.  It may even harm performance in environments like mod_perl,
+where as much as possible of a module's code should be loaded during
+startup.
+
+=item build_class
+
+[version 0.28]
+
+The Module::Build class or subclass to use in the build script.
+Defaults to "Module::Build" or the class name passed to or created by
+a call to L</subclass()>.  This property is useful if you're
+writing a custom Module::Build subclass and have a bootstrapping
+problem--that is, your subclass requires modules that may not be
+installed when C<perl Build.PL> is executed, but you've listed in
+L</build_requires> so that they should be available when C<./Build> is
+executed.
+
+=item build_requires
+
+[version 0.07]
+
+Modules listed in this section are necessary to build and install the
+given module, but are not necessary for regular usage of it.  This is
+actually an important distinction - it allows for tighter control over
+the body of installed modules, and facilitates correct dependency
+checking on binary/packaged distributions of the module.
+
+See the documentation for L<Module::Build::Authoring/"PREREQUISITES">
+for the details of how requirements can be specified.
+
+=item create_packlist
+
+[version 0.28]
+
+If true, this parameter tells Module::Build to create a F<.packlist>
+file during the C<install> action, just like C<ExtUtils::MakeMaker> does.
+The file is created in a subdirectory of the C<arch> installation
+location.  It is used by some other tools (CPAN, CPANPLUS, etc.) for
+determining what files are part of an install.
+
+The default value is true.  This parameter was introduced in
+Module::Build version 0.2609; previously no packlists were ever
+created by Module::Build.
+
+=item c_source
+
+[version 0.04]
+
+An optional C<c_source> argument specifies a directory which contains
+C source files that the rest of the build may depend on.  Any C<.c>
+files in the directory will be compiled to object files.  The
+directory will be added to the search path during the compilation and
+linking phases of any C or XS files.
+
+=item conflicts
+
+[version 0.07]
+
+Modules listed in this section conflict in some serious way with the
+given module.  C<Module::Build> (or some higher-level tool) will
+refuse to install the given module if the given module/version is also
+installed.
+
+See the documentation for L<Module::Build::Authoring/"PREREQUISITES">
+for the details of how requirements can be specified.
+
+=item create_license
+
+[version 0.31]
+
+This parameter tells Module::Build to automatically create a
+F<LICENSE> file at the top level of your distribution, containing the
+full text of the author's chosen license.  This requires
+C<Software::License> on the author's machine, and further requires
+that the C<license> parameter specifies a license that it knows about.
+
+=item create_makefile_pl
+
+[version 0.19]
+
+This parameter lets you use C<Module::Build::Compat> during the
+C<distdir> (or C<dist>) action to automatically create a Makefile.PL
+for compatibility with C<ExtUtils::MakeMaker>.  The parameter's value
+should be one of the styles named in the L<Module::Build::Compat>
+documentation.
+
+=item create_readme
+
+[version 0.22]
+
+This parameter tells Module::Build to automatically create a F<README>
+file at the top level of your distribution.  Currently it will simply
+use C<Pod::Text> (or C<Pod::Readme> if it's installed) on the file
+indicated by C<dist_version_from> and put the result in the F<README>
+file.  This is by no means the only recommended style for writing a
+F<README>, but it seems to be one common one used on the CPAN.
+
+If you generate a F<README> in this way, it's probably a good idea to
+create a separate F<INSTALL> file if that information isn't in the
+generated F<README>.
+
+=item dist_abstract
+
+[version 0.20]
+
+This should be a short description of the distribution.  This is used when
+generating metadata for F<META.yml> and PPD files.  If it is not given
+then C<Module::Build> looks in the POD of the module from which it gets
+the distribution's version.  If it finds a POD section marked "=head1
+NAME", then it looks for the first line matching C<\s+-\s+(.+)>,
+and uses the captured text as the abstract.
+
+=item dist_author
+
+[version 0.20]
+
+This should be something like "John Doe <jdoe@example.com>", or if
+there are multiple authors, an anonymous array of strings may be
+specified.  This is used when generating metadata for F<META.yml> and
+PPD files.  If this is not specified, then C<Module::Build> looks at
+the module from which it gets the distribution's version.  If it finds
+a POD section marked "=head1 AUTHOR", then it uses the contents of
+this section.
+
+=item dist_name
+
+[version 0.11]
+
+Specifies the name for this distribution.  Most authors won't need to
+set this directly, they can use C<module_name> to set C<dist_name> to
+a reasonable default.  However, some agglomerative distributions like
+C<libwww-perl> or C<bioperl> have names that don't correspond directly
+to a module name, so C<dist_name> can be set independently.
+
+=item dist_version
+
+[version 0.11]
+
+Specifies a version number for the distribution.  See L</module_name>
+or L</dist_version_from> for ways to have this set automatically from a
+C<$VERSION> variable in a module.  One way or another, a version
+number needs to be set.
+
+=item dist_version_from
+
+[version 0.11]
+
+Specifies a file to look for the distribution version in.  Most
+authors won't need to set this directly, they can use L</module_name>
+to set it to a reasonable default.
+
+The version is extracted from the specified file according to the same
+rules as L<ExtUtils::MakeMaker> and C<CPAN.pm>.  It involves finding
+the first line that matches the regular expression
+
+   /([\$*])(([\w\:\']*)\bVERSION)\b.*\=/
+
+eval()-ing that line, then checking the value of the C<$VERSION>
+variable.  Quite ugly, really, but all the modules on CPAN depend on
+this process, so there's no real opportunity to change to something
+better.
+
+If the target file of L</dist_version_from> contains more than one package
+declaration, the version returned will be the one matching the configured
+L</module_name>.
+
+=item dynamic_config
+
+[version 0.07]
+
+A boolean flag indicating whether the F<Build.PL> file must be
+executed, or whether this module can be built, tested and installed
+solely from consulting its metadata file.  The main reason to set this
+to a true value is that your module performs some dynamic
+configuration as part of its build/install process.  If the flag is
+omitted, the F<META.yml> spec says that installation tools should
+treat it as 1 (true), because this is a safer way to behave.
+
+Currently C<Module::Build> doesn't actually do anything with this flag
+- it's up to higher-level tools like C<CPAN.pm> to do something useful
+with it.  It can potentially bring lots of security, packaging, and
+convenience improvements.
+
+=item extra_compiler_flags
+
+=item extra_linker_flags
+
+[version 0.19]
+
+These parameters can contain array references (or strings, in which
+case they will be split into arrays) to pass through to the compiler
+and linker phases when compiling/linking C code.  For example, to tell
+the compiler that your code is C++, you might do:
+
+  my $build = Module::Build->new
+    (
+     module_name          => 'Foo::Bar',
+     extra_compiler_flags => ['-x', 'c++'],
+    );
+
+To link your XS code against glib you might write something like:
+
+  my $build = Module::Build->new
+    (
+     module_name          => 'Foo::Bar',
+     dynamic_config       => 1,
+     extra_compiler_flags => scalar `glib-config --cflags`,
+     extra_linker_flags   => scalar `glib-config --libs`,
+    );
+
+=item get_options
+
+[version 0.26]
+
+You can pass arbitrary command line options to F<Build.PL> or
+F<Build>, and they will be stored in the Module::Build object and can
+be accessed via the L</args()> method.  However, sometimes you want
+more flexibility out of your argument processing than this allows.  In
+such cases, use the C<get_options> parameter to pass in a hash
+reference of argument specifications, and the list of arguments to
+F<Build.PL> or F<Build> will be processed according to those
+specifications before they're passed on to C<Module::Build>'s own
+argument processing.
+
+The supported option specification hash keys are:
+
+
+=over 4
+
+=item type
+
+The type of option.  The types are those supported by Getopt::Long; consult
+its documentation for a complete list.  Typical types are C<=s> for strings,
+C<+> for additive options, and C<!> for negatable options.  If the
+type is not specified, it will be considered a boolean, i.e. no
+argument is taken and a value of 1 will be assigned when the option is
+encountered.
+
+=item store
+
+A reference to a scalar in which to store the value passed to the option.
+If not specified, the value will be stored under the option name in the
+hash returned by the C<args()> method.
+
+=item default
+
+A default value for the option.  If no default value is specified and no option
+is passed, then the option key will not exist in the hash returned by
+C<args()>.
+
+=back
+
+
+You can combine references to your own variables or subroutines with
+unreferenced specifications, for which the result will also be stored in the
+hash returned by C<args()>.  For example:
+
+  my $loud = 0;
+  my $build = Module::Build->new
+    (
+     module_name => 'Foo::Bar',
+     get_options => {
+                     Loud =>     { store => \$loud },
+                     Dbd  =>     { type  => '=s'   },
+                     Quantity => { type  => '+'    },
+                    }
+    );
+
+  print STDERR "HEY, ARE YOU LISTENING??\n" if $loud;
+  print "We'll use the ", $build->args('Dbd'), " DBI driver\n";
+  print "Are you sure you want that many?\n"
+    if $build->args('Quantity') > 2;
+
+The arguments for such a specification can be called like so:
+
+  perl Build.PL --Loud --Dbd=DBD::pg --Quantity --Quantity --Quantity
+
+B<WARNING:> Any option specifications that conflict with Module::Build's own
+options (defined by its properties) will throw an exception.  Use capitalized
+option names to avoid unintended conflicts with future Module::Build options.
+
+Consult the Getopt::Long documentation for details on its usage.
+
+=item include_dirs
+
+[version 0.24]
+
+Specifies any additional directories in which to search for C header
+files.  May be given as a string indicating a single directory, or as
+a list reference indicating multiple directories.
+
+=item install_path
+
+[version 0.19]
+
+You can set paths for individual installable elements by using the
+C<install_path> parameter:
+
+  my $build = Module::Build->new
+    (
+     ...other stuff here...
+     install_path => {
+                      lib  => '/foo/lib',
+                      arch => '/foo/lib/arch',
+                     }
+    );
+
+=item installdirs
+
+[version 0.19]
+
+Determines where files are installed within the normal perl hierarchy
+as determined by F<Config.pm>.  Valid values are: C<core>, C<site>,
+C<vendor>.  The default is C<site>.  See
+L<Module::Build/"INSTALL PATHS">
+
+=item license
+
+[version 0.07]
+
+Specifies the licensing terms of your distribution.  Valid options include:
+
+
+=over 4
+
+=item apache
+
+The distribution is licensed under the Apache License, Version 2.0
+(L<http://apache.org/licenses/LICENSE-2.0>).

+(L<http://apache.org/licenses/LICENSE-1.1>).
+
+=item artistic
+
+The distribution is licensed under the Artistic License, as specified
+by the F<Artistic> file in the standard Perl distribution.
+
+=item artistic_2
+
+The distribution is licensed under the Artistic 2.0 License
+(L<http://opensource.org/licenses/artistic-license-2.0.php>.)
+
+=item bsd

+The distribution is licensed under the BSD License
+(L<http://www.opensource.org/licenses/bsd-license.php>).
+
+=item gpl
+
+The distribution is licensed under the terms of the GNU General
+Public License (L<http://www.opensource.org/licenses/gpl-license.php>).
+
+=item lgpl
+
+The distribution is licensed under the terms of the GNU Lesser
+General Public License
+(L<http://www.opensource.org/licenses/lgpl-license.php>).
+
+=item mit
+
+The distribution is licensed under the MIT License
+(L<http://opensource.org/licenses/mit-license.php>).
+
+=item mozilla
+
+The distribution is licensed under the Mozilla Public
+License.  (L<http://opensource.org/licenses/mozilla1.0.php> or
+L<http://opensource.org/licenses/mozilla1.1.php>)
+
+=item open_source
+
+The distribution is licensed under some other Open Source
+Initiative-approved license listed at
+L<http://www.opensource.org/licenses/>.
+
+=item perl
+
+The distribution may be copied and redistributed under the same terms
+as Perl itself (this is by far the most common licensing option for
+modules on CPAN).  This is a dual license, in which the user may
+choose between either the GPL or the Artistic license.
+
+=item restrictive
+
+The distribution may not be redistributed without special permission
+from the author and/or copyright holder.
+
+=item unrestricted
+
+The distribution is licensed under a license that is B<not> approved
+by www.opensource.org but that allows distribution without
+restrictions.
+
+=back
+
+
+Note that you must still include the terms of your license in your
+documentation - this field only lets automated tools figure out your
+licensing restrictions.  Humans still need something to read.  If you
+choose to provide this field, you should make sure that you keep it in
+sync with your written documentation if you ever change your licensing
+terms.
+
+You may also use a license type of C<unknown> if you don't wish to
+specify your terms in the metadata.
+
+It is a fatal error to use a license other than the ones mentioned
+above.  This is not because I wish to impose licensing terms on you -
+please let me know if you would like another license option to be
+added to the list.  I just started out with a small set of licenses to
+keep things simple, figuring I'd let people with actual working
+knowledge in this area tell me what to do.  So if that's you, drop me
+a line.
+
+=item meta_add
+
+[version 0.28]
+
+A hash of key/value pairs that should be added to the F<META.yml> file
+during the C<distmeta> action.  Any existing entries with the same
+names will be overridden.
+
+See the L</"MODULE METADATA"> section for details.
+
+=item meta_merge
+
+[version 0.28]
+
+A hash of key/value pairs that should be merged into the F<META.yml>
+file during the C<distmeta> action.  Any existing entries with the
+same names will be overridden.
+
+The only difference between C<meta_add> and C<meta_merge> is their
+behavior on hash-valued and array-valued entries: C<meta_add> will
+completely blow away the existing hash or array value, but
+C<meta_merge> will merge the supplied data into the existing hash or
+array value.
+
+See the L</"MODULE METADATA"> section for details.
+
+=item module_name
+
+[version 0.03]
+
+The C<module_name> is a shortcut for setting default values of
+C<dist_name> and C<dist_version_from>, reflecting the fact that the
+majority of CPAN distributions are centered around one "main" module.
+For instance, if you set C<module_name> to C<Foo::Bar>, then
+C<dist_name> will default to C<Foo-Bar> and C<dist_version_from> will
+default to C<lib/Foo/Bar.pm>.  C<dist_version_from> will in turn be
+used to set C<dist_version>.
+
+Setting C<module_name> won't override a C<dist_*> parameter you
+specify explicitly.
+
+=item needs_compiler
+
+[version 0.36]
+
+The C<needs_compiler> parameter indicates whether a compiler is required to
+build the distsribution.  The default is false, unless XS files are found or
+the C<c_source> parameter is set, in which case it is true.  If true,
+L<ExtUtils::CBuilder> is automatically added to C<build_requires> if needed.
+
+For a distribution where a compiler is I<optional>, e.g. a dual XS/pure-Perl
+distribution, C<needs_compiler> should explicitly be set to a false value.
+
+=item PL_files
+
+[version 0.06]
+
+An optional parameter specifying a set of C<.PL> files in your
+distribution.  These will be run as Perl scripts prior to processing
+the rest of the files in your distribution with the name of the file
+they're generating as an argument.  They are usually used as templates
+for creating other files dynamically, so that a file like
+C<lib/Foo/Bar.pm.PL> might create the file C<lib/Foo/Bar.pm>.
+
+The files are specified with the C<.PL> files as hash keys, and the
+file(s) they generate as hash values, like so:
+
+  my $build = Module::Build->new
+    (
+     module_name => 'Foo::Bar',
+     ...
+     PL_files => { 'lib/Foo/Bar.pm.PL' => 'lib/Foo/Bar.pm' },
+    );
+
+Note that the path specifications are I<always> given in Unix-like
+format, not in the style of the local system.
+
+If your C<.PL> scripts don't create any files, or if they create files
+with unexpected names, or even if they create multiple files, you can
+indicate that so that Module::Build can properly handle these created
+files:
+
+  PL_files => {
+               'lib/Foo/Bar.pm.PL' => 'lib/Foo/Bar.pm',
+               'lib/something.PL'  => ['/lib/something', '/lib/else'],
+               'lib/funny.PL'      => [],
+              }
+
+Here's an example of a simple PL file.
+
+    my $output_file = shift;
+    open my $fh, ">", $output_file or die "Can't open $output_file: $!";
+
+    print $fh <<'END';
+    #!/usr/bin/perl
+
+    print "Hello, world!\n";
+    END
+
+PL files are not installed by default, so its safe to put them in
+F<lib/> and F<bin/>.
+
+
+=item pm_files
+
+[version 0.19]
+
+An optional parameter specifying the set of C<.pm> files in this
+distribution, specified as a hash reference whose keys are the files'
+locations in the distributions, and whose values are their logical
+locations based on their package name, i.e. where they would be found
+in a "normal" Module::Build-style distribution.  This parameter is
+mainly intended to support alternative layouts of files.
+
+For instance, if you have an old-style C<MakeMaker> distribution for a
+module called C<Foo::Bar> and a F<Bar.pm> file at the top level of the
+distribution, you could specify your layout in your C<Build.PL> like
+this:
+
+  my $build = Module::Build->new
+    (
+     module_name => 'Foo::Bar',
+     ...
+     pm_files => { 'Bar.pm' => 'lib/Foo/Bar.pm' },
+    );
+
+Note that the values should include C<lib/>, because this is where
+they would be found in a "normal" Module::Build-style distribution.
+
+Note also that the path specifications are I<always> given in
+Unix-like format, not in the style of the local system.
+
+=item pod_files
+
+[version 0.19]
+
+Just like C<pm_files>, but used for specifying the set of C<.pod>
+files in your distribution.
+
+=item recommends
+
+[version 0.08]
+
+This is just like the L</requires> argument, except that modules listed
+in this section aren't essential, just a good idea.  We'll just print
+a friendly warning if one of these modules aren't found, but we'll
+continue running.
+
+If a module is recommended but not required, all tests should still
+pass if the module isn't installed.  This may mean that some tests
+may be skipped if recommended dependencies aren't present.
+
+Automated tools like CPAN.pm should inform the user when recommended
+modules aren't installed, and it should offer to install them if it
+wants to be helpful.
+
+See the documentation for L<Module::Build::Authoring/"PREREQUISITES">
+for the details of how requirements can be specified.
+
+=item recursive_test_files
+
+[version 0.28]
+
+Normally, C<Module::Build> does not search subdirectories when looking
+for tests to run. When this options is set it will search recursively
+in all subdirectories of the standard 't' test directory.
+
+=item requires
+
+[version 0.07]
+
+An optional C<requires> argument specifies any module prerequisites
+that the current module depends on.
+
+One note: currently C<Module::Build> doesn't actually I<require> the
+user to have dependencies installed, it just strongly urges.  In the
+future we may require it.  There's also a L</recommends> section for
+things that aren't absolutely required.
+
+Automated tools like CPAN.pm should refuse to install a module if one
+of its dependencies isn't satisfied, unless a "force" command is given
+by the user.  If the tools are helpful, they should also offer to
+install the dependencies.
+
+A synonym for C<requires> is C<prereq>, to help succour people
+transitioning from C<ExtUtils::MakeMaker>.  The C<requires> term is
+preferred, but the C<prereq> term will remain valid in future
+distributions.
+
+See the documentation for L<Module::Build::Authoring/"PREREQUISITES">
+for the details of how requirements can be specified.
+
+=item script_files
+
+[version 0.18]
+
+An optional parameter specifying a set of files that should be
+installed as executable Perl scripts when the module is installed.
+May be given as an array reference of the files, as a hash reference
+whose keys are the files (and whose values will currently be ignored),
+as a string giving the name of a directory in which to find scripts,
+or as a string giving the name of a single script file.
+
+The default is to install any scripts found in a F<bin> directory at
+the top level of the distribution, minus any keys of L<PL_files>.
+
+For backward compatibility, you may use the parameter C<scripts>
+instead of C<script_files>.  Please consider this usage deprecated,
+though it will continue to exist for several version releases.
+
+=item share_dir
+
+[version 0.36]
+
+An optional parameter specifying directories of static data files to
+be installed as read-only files for use with L<File::ShareDir>.  The
+C<share_dir> property supports both distribution-level and
+module-level share files.
+
+The simplest use of C<share_dir> is to set it to a directory name or an
+arrayref of directory names containing files to be installed in the
+distribution-level share directory.
+
+  share_dir => 'share'
+
+Alternatively, if C<share_dir> is a hashref, it may have C<dist> or
+C<module> keys providing full flexibility in defining how share
+directories should be installed.
+
+  share_dir => {
+    dist => [ 'examples', 'more_examples' ],
+    module => {
+      Foo::Templates => ['share/html', 'share/text'],
+      Foo::Config    => 'share/config',
+    }
+  }
+
+If C<share_dir> is set, then File::ShareDir will automatically be added
+to the C<requires> hash.
+
+=item sign
+
+[version 0.16]
+
+If a true value is specified for this parameter, L<Module::Signature>
+will be used (via the 'distsign' action) to create a SIGNATURE file
+for your distribution during the 'distdir' action, and to add the
+SIGNATURE file to the MANIFEST (therefore, don't add it yourself).
+
+The default value is false.  In the future, the default may change to
+true if you have C<Module::Signature> installed on your system.
+
+=item test_files
+
+[version 0.23]
+
+An optional parameter specifying a set of files that should be used as
+C<Test::Harness>-style regression tests to be run during the C<test>
+action.  May be given as an array reference of the files, or as a hash
+reference whose keys are the files (and whose values will currently be
+ignored).  If the argument is given as a single string (not in an
+array reference), that string will be treated as a C<glob()> pattern
+specifying the files to use.
+
+The default is to look for a F<test.pl> script in the top-level
+directory of the distribution, and any files matching the glob pattern
+C<*.t> in the F<t/> subdirectory.  If the C<recursive_test_files>
+property is true, then the C<t/> directory will be scanned recursively
+for C<*.t> files.
+
+=item use_tap_harness
+
+[version 0.2808_03]
+
+An optional parameter indicating whether or not to use TAP::Harness for
+testing rather than Test::Harness. Defaults to false. If set to true, you must
+therefore be sure to add TAP::Harness as a requirement for your module in
+L</build_requires>. Implicitly set to a true value if C<tap_harness_args> is
+specified.
+
+=item tap_harness_args
+
+[version 0.2808_03]
+
+An optional parameter specifying parameters to be passed to TAP::Harness when
+running tests. Must be given as a hash reference of parameters; see the
+L<TAP::Harness|TAP::Harness> documentation for details. Note that specifying
+this parameter will implicitly set C<use_tap_harness> to a true value. You
+must therefore be sure to add TAP::Harness as a requirement for your module in
+L</build_requires>.
+
+=item xs_files
+
+[version 0.19]
+
+Just like C<pm_files>, but used for specifying the set of C<.xs>
+files in your distribution.
+
+=back
+
+
+=item new_from_context(%args)
+
+[version 0.28]
+
+When called from a directory containing a F<Build.PL> script (in other words,
+the base directory of a distribution), this method will run the F<Build.PL> and
+call C<resume()> to return the resulting C<Module::Build> object to the caller.
+Any key-value arguments given to C<new_from_context()> are essentially like
+command line arguments given to the F<Build.PL> script, so for example you
+could pass C<< verbose => 1 >> to this method to turn on verbosity.
+
+=item resume()
+
+[version 0.03]
+
+You'll probably never call this method directly, it's only called from the
+auto-generated C<Build> script (and the C<new_from_context> method).  The
+C<new()> method is only called once, when the user runs C<perl Build.PL>.
+Thereafter, when the user runs C<Build test> or another action, the
+C<Module::Build> object is created using the C<resume()> method to
+re-instantiate with the settings given earlier to C<new()>.
+
+=item subclass()
+
+[version 0.06]
+
+This creates a new C<Module::Build> subclass on the fly, as described
+in the L<Module::Build::Authoring/"SUBCLASSING"> section.  The caller
+must provide either a C<class> or C<code> parameter, or both.  The
+C<class> parameter indicates the name to use for the new subclass, and
+defaults to C<MyModuleBuilder>.  The C<code> parameter specifies Perl
+code to use as the body of the subclass.
+
+=item add_property
+
+[version 0.31]
+
+  package 'My::Build';
+  use base 'Module::Build';
+  __PACKAGE__->add_property( 'pedantic' );
+  __PACKAGE__->add_property( answer => 42 );
+  __PACKAGE__->add_property(
+     'epoch',
+      default => sub { time },
+      check   => sub {
+          return 1 if /^\d+$/;
+          shift->property_error( "'$_' is not an epoch time" );
+          return 0;
+      },
+  );
+
+Adds a property to a Module::Build class. Properties are those attributes of a
+Module::Build object which can be passed to the constructor and which have
+accessors to get and set them. All of the core properties, such as
+C<module_name> and C<license>, are defined using this class method.
+
+The first argument to C<add_property()> is always the name of the property.
+The second argument can be either a default value for the property, or a list
+of key/value pairs. The supported keys are:
+
+=over
+
+=item C<default>
+
+The default value. May optionally be specified as a code reference, in which
+case the return value from the execution of the code reference will be used.
+If you need the default to be a code reference, just use a code reference to
+return it, e.g.:
+
+      default => sub { sub { ... } },
+
+=item C<check>
+
+A code reference that checks that a value specified for the property is valid.
+During the execution of the code reference, the new value will be included in
+the C<$_> variable. If the value is correct, the C<check> code reference
+should return true. If the value is not correct, it sends an error message to
+C<property_error()> and returns false.
+
+=back
+
+When this method is called, a new property will be installed in the
+Module::Build class, and an accessor will be built to allow the property to be
+get or set on the build object.
+
+  print $build->pedantic, $/;
+  $build->pedantic(0);
+
+If the default value is a hash reference, this generates a special-case
+accessor method, wherein individual key/value pairs may be set or fetched:
+
+  print "stuff{foo} is: ", $build->stuff( 'foo' ), $/;
+  $build->stuff( foo => 'bar' );
+  print $build->stuff( 'foo' ), $/; # Outputs "bar"
+
+Of course, you can still set the entire hash reference at once, as well:
+
+  $build->stuff( { foo => 'bar', baz => 'yo' } );
+
+In either case, if a C<check> has been specified for the property, it will be
+applied to the entire hash. So the check code reference should look something
+like:
+
+      check => sub {
+            return 1 if defined $_ && exists $_->{foo};
+            shift->property_error(qq{Property "stuff" needs "foo"});
+            return 0;

+=over 4
+
+=item add_build_element($type)
+
+[version 0.26]
+
+Adds a new type of entry to the build process.  Accepts a single
+string specifying its type-name.  There must also be a method defined
+to process things of that type, e.g. if you add a build element called
+C<'foo'>, then you must also define a method called
+C<process_foo_files()>.
+
+See also
+L<Module::Build::Cookbook/"Adding new file types to the build process">.
+
+=item add_to_cleanup(@files)
+
+[version 0.03]
+
+You may call C<< $self->add_to_cleanup(@patterns) >> to tell
+C<Module::Build> that certain files should be removed when the user
+performs the C<Build clean> action.  The arguments to the method are
+patterns suitable for passing to Perl's C<glob()> function, specified
+in either Unix format or the current machine's native format.  It's
+usually convenient to use Unix format when you hard-code the filenames
+(e.g. in F<Build.PL>) and the native format when the names are
+programmatically generated (e.g. in a testing script).
+
+I decided to provide a dynamic method of the C<$build> object, rather
+than just use a static list of files named in the F<Build.PL>, because
+these static lists can get difficult to manage.  I usually prefer to
+keep the responsibility for registering temporary files close to the
+code that creates them.
+
+=item args()
+
+[version 0.26]
+
+  my $args_href = $build->args;
+  my %args = $build->args;
+  my $arg_value = $build->args($key);
+  $build->args($key, $value);
+
+This method is the preferred interface for retrieving the arguments passed via
+command line options to F<Build.PL> or F<Build>, minus the Module-Build
+specific options.
+
+When called in in a scalar context with no arguments, this method returns a
+reference to the hash storing all of the arguments; in an array context, it
+returns the hash itself.  When passed a single argument, it returns the value
+stored in the args hash for that option key.  When called with two arguments,
+the second argument is assigned to the args hash under the key passed as the
+first argument.
+
+=item autosplit_file($from, $to)
+
+[version 0.28]
+
+Invokes the L<AutoSplit> module on the C<$from> file, sending the
+output to the C<lib/auto> directory inside C<$to>.  C<$to> is
+typically the C<blib/> directory.
+
+=item base_dir()
+
+[version 0.14]
+
+Returns a string containing the root-level directory of this build,
+i.e. where the C<Build.PL> script and the C<lib> directory can be
+found.  This is usually the same as the current working directory,
+because the C<Build> script will C<chdir()> into this directory as
+soon as it begins execution.
+
+=item build_requires()
+
+[version 0.21]
+
+Returns a hash reference indicating the C<build_requires>
+prerequisites that were passed to the C<new()> method.
+
+=item can_action( $action )
+
+Returns a reference to the method that defines C<$action>, or false
+otherwise. This is handy for actions defined (or maybe not!) in subclasses.
+
+[version 0.32_xx]
+
+=item cbuilder()
+
+[version 0.2809]
+
+Returns the internal ExtUtils::CBuilder object that can be used for
+compiling & linking C code.  If no such object is available (e.g. if
+the system has no compiler installed) an exception will be thrown.
+
+=item check_installed_status($module, $version)
+
+[version 0.11]
+
+This method returns a hash reference indicating whether a version
+dependency on a certain module is satisfied.  The C<$module> argument
+is given as a string like C<"Data::Dumper"> or C<"perl">, and the
+C<$version> argument can take any of the forms described in L</requires>
+above.  This allows very fine-grained version checking.
+
+The returned hash reference has the following structure:
+
+  {
+   ok => $whether_the_dependency_is_satisfied,
+   have => $version_already_installed,
+   need => $version_requested, # Same as incoming $version argument
+   message => $informative_error_message,
+  }
+
+If no version of C<$module> is currently installed, the C<have> value
+will be the string C<< "<none>" >>.  Otherwise the C<have> value will
+simply be the version of the installed module.  Note that this means
+that if C<$module> is installed but doesn't define a version number,
+the C<have> value will be C<undef> - this is why we don't use C<undef>
+for the case when C<$module> isn't installed at all.
+
+This method may be called either as an object method
+(C<< $build->check_installed_status($module, $version) >>)
+or as a class method
+(C<< Module::Build->check_installed_status($module, $version) >>).
+
+=item check_installed_version($module, $version)
+
+[version 0.05]
+
+Like L<check_installed_status()|/"check_installed_status($module, $version)">,
+but simply returns true or false depending on whether module
+C<$module> satisfies the dependency C<$version>.
+
+If the check succeeds, the return value is the actual version of
+C<$module> installed on the system.  This allows you to do the
+following:
+
+  my $installed = $build->check_installed_version('DBI', '1.15');
+  if ($installed) {
+    print "Congratulations, version $installed of DBI is installed.\n";
+  } else {
+    die "Sorry, you must install DBI.\n";
+  }
+
+If the check fails, we return false and set C<$@> to an informative
+error message.
+
+If C<$version> is any non-true value (notably zero) and any version of
+C<$module> is installed, we return true.  In this case, if C<$module>
+doesn't define a version, or if its version is zero, we return the
+special value "0 but true", which is numerically zero, but logically
+true.
+
+In general you might prefer to use C<check_installed_status> if you
+need detailed information, or this method if you just need a yes/no
+answer.
+
+=item compare_versions($v1, $op, $v2)
+
+[version 0.28]
+
+Compares two module versions C<$v1> and C<$v2> using the operator
+C<$op>, which should be one of Perl's numeric operators like C<!=> or
+C<< >= >> or the like.  We do at least a halfway-decent job of
+handling versions that aren't strictly numeric, like C<0.27_02>, but
+exotic stuff will likely cause problems.
+
+In the future, the guts of this method might be replaced with a call
+out to C<version.pm>.
+
+=item config($key)
+
+=item config($key, $value)
+
+=item config() [deprecated]
+
+[version 0.22]
+
+With a single argument C<$key>, returns the value associated with that
+key in the C<Config.pm> hash, including any changes the author or user
+has specified.
+
+With C<$key> and C<$value> arguments, sets the value for future
+callers of C<config($key)>.
+
+With no arguments, returns a hash reference containing all such
+key-value pairs.  This usage is deprecated, though, because it's a
+resource hog and violates encapsulation.
+
+=item config_data($name)
+
+=item config_data($name => $value)
+
+[version 0.26]
+
+With a single argument, returns the value of the configuration
+variable C<$name>.  With two arguments, sets the given configuration
+variable to the given value.  The value may be any Perl scalar that's
+serializable with C<Data::Dumper>.  For instance, if you write a
+module that can use a MySQL or PostgreSQL back-end, you might create
+configuration variables called C<mysql_connect> and
+C<postgres_connect>, and set each to an array of connection parameters
+for C<< DBI->connect() >>.
+
+Configuration values set in this way using the Module::Build object
+will be available for querying during the build/test process and after
+installation via the generated C<...::ConfigData> module, as
+C<< ...::ConfigData->config($name) >>.
+
+The L<feature()|/"feature($name)"> and C<config_data()> methods represent
+Module::Build's main support for configuration of installed modules.
+See also L<Module::Build::Authoring/"SAVING CONFIGURATION INFORMATION">.
+
+=item conflicts()
+
+[version 0.21]
+
+Returns a hash reference indicating the C<conflicts> prerequisites
+that were passed to the C<new()> method.
+
+=item contains_pod($file) [deprecated]
+
+[version 0.20]
+
+[Deprecated] Please see L<Module::Build::ModuleInfo> instead.
+
+Returns true if the given file appears to contain POD documentation.
+Currently this checks whether the file has a line beginning with
+'=pod', '=head', or '=item', but the exact semantics may change in the
+future.
+
+=item copy_if_modified(%parameters)
+
+[version 0.19]
+
+Takes the file in the C<from> parameter and copies it to the file in
+the C<to> parameter, or the directory in the C<to_dir> parameter, if
+the file has changed since it was last copied (or if it doesn't exist
+in the new location).  By default the entire directory structure of
+C<from> will be copied into C<to_dir>; an optional C<flatten>
+parameter will copy into C<to_dir> without doing so.
+
+Returns the path to the destination file, or C<undef> if nothing
+needed to be copied.
+
+Any directories that need to be created in order to perform the
+copying will be automatically created.
+
+The destination file is set to read-only. If the source file has the
+executable bit set, then the destination file will be made executable.
+
+=item create_build_script()
+
+[version 0.05]
+
+Creates an executable script called C<Build> in the current directory
+that will be used to execute further user actions.  This script is
+roughly analogous (in function, not in form) to the Makefile created
+by C<ExtUtils::MakeMaker>.  This method also creates some temporary
+data in a directory called C<_build/>.  Both of these will be removed
+when the C<realclean> action is performed.
+
+Among the files created in C<_build/> is a F<_build/prereqs> file
+containing the set of prerequisites for this distribution, as a hash
+of hashes.  This file may be C<eval()>-ed to obtain the authoritative
+set of prerequisites, which might be different from the contents of
+F<META.yml> (because F<Build.PL> might have set them dynamically).
+But fancy developers take heed: do not put any fancy custom runtime
+code in the F<_build/prereqs> file, leave it as a static declaration
+containing only strings and numbers.  Similarly, do not alter the
+structure of the internal C<< $self->{properties}{requires} >> (etc.)
+data members, because that's where this data comes from.
+
+=item current_action()
+
+[version 0.28]
+
+Returns the name of the currently-running action, such as "build" or
+"test".  This action is not necessarily the action that was originally
+invoked by the user.  For example, if the user invoked the "test"
+action, current_action() would initially return "test".  However,
+action "test" depends on action "code", so current_action() will
+return "code" while that dependency is being executed.  Once that
+action has completed, current_action() will again return "test".
+
+If you need to know the name of the original action invoked by the
+user, see L</invoked_action()> below.
+
+=item depends_on(@actions)
+
+[version 0.28]
+
+Invokes the named action or list of actions in sequence.  Using this
+method is preferred to calling the action explicitly because it
+performs some internal record-keeping, and it ensures that the same
+action is not invoked multiple times (note: in future versions of
+Module::Build it's conceivable that this run-only-once mechanism will
+be changed to something more intelligent).
+
+Note that the name of this method is something of a misnomer; it
+should really be called something like
+C<invoke_actions_unless_already_invoked()> or something, but for
+better or worse (perhaps better!) we were still thinking in
+C<make>-like dependency terms when we created this method.
+
+See also L<dispatch()|/"dispatch($action, %args)">.  The main
+distinction between the two is that C<depends_on()> is meant to call
+an action from inside another action, whereas C<dispatch()> is meant
+to set the very top action in motion.
+
+=item dir_contains($first_dir, $second_dir)
+
+[version 0.28]
+
+Returns true if the first directory logically contains the second
+directory.  This is just a convenience function because C<File::Spec>
+doesn't really provide an easy way to figure this out (but
+C<Path::Class> does...).
+
+=item dispatch($action, %args)
+
+[version 0.03]
+
+Invokes the build action C<$action>.  Optionally, a list of options
+and their values can be passed in.  This is equivalent to invoking an
+action at the command line, passing in a list of options.
+
+Custom options that have not been registered must be passed in as a
+hash reference in a key named "args":
+
+  $build->dispatch('foo', verbose => 1, args => { my_option => 'value' });
+
+This method is intended to be used to programmatically invoke build
+actions, e.g. by applications controlling Module::Build-based builds
+rather than by subclasses.
+
+See also L<depends_on()|/"depends_on(@actions)">.  The main
+distinction between the two is that C<depends_on()> is meant to call
+an action from inside another action, whereas C<dispatch()> is meant
+to set the very top action in motion.
+
+=item dist_dir()
+
+[version 0.28]
+
+Returns the name of the directory that will be created during the
+C<dist> action.  The name is derived from the C<dist_name> and
+C<dist_version> properties.
+
+=item dist_name()
+
+[version 0.21]
+
+Returns the name of the current distribution, as passed to the
+C<new()> method in a C<dist_name> or modified C<module_name>
+parameter.
+
+=item dist_version()
+
+[version 0.21]
+
+Returns the version of the current distribution, as determined by the
+C<new()> method from a C<dist_version>, C<dist_version_from>, or
+C<module_name> parameter.
+
+=item do_system($cmd, @args)
+
+[version 0.21]
+
+This is a fairly simple wrapper around Perl's C<system()> built-in
+command.  Given a command and an array of optional arguments, this
+method will print the command to C<STDOUT>, and then execute it using
+Perl's C<system()>.  It returns true or false to indicate success or
+failure (the opposite of how C<system()> works, but more intuitive).
+
+Note that if you supply a single argument to C<do_system()>, it
+will/may be processed by the system's shell, and any special
+characters will do their special things.  If you supply multiple
+arguments, no shell will get involved and the command will be executed
+directly.
+
+=item feature($name)
+
+=item feature($name => $value)
+
+[version 0.26]
+
+With a single argument, returns true if the given feature is set.
+With two arguments, sets the given feature to the given boolean value.
+In this context, a "feature" is any optional functionality of an
+installed module.  For instance, if you write a module that could
+optionally support a MySQL or PostgreSQL backend, you might create
+features called C<mysql_support> and C<postgres_support>, and set them
+to true/false depending on whether the user has the proper databases
+installed and configured.
+
+Features set in this way using the Module::Build object will be
+available for querying during the build/test process and after
+installation via the generated C<...::ConfigData> module, as
+C<< ...::ConfigData->feature($name) >>.
+
+The C<feature()> and C<config_data()> methods represent
+Module::Build's main support for configuration of installed modules.
+See also L<Module::Build::Authoring/"SAVING CONFIGURATION INFORMATION">.
+
+=item fix_shebang_line(@files)
+
+[version 0.??]
+
+Modify any "shebang" line in the specified files to use the path to the
+perl executable being used for the current build.  Files are modified
+in-place.  The existing shebang line must have a command that contains
+"C<perl>"; arguments to the command do not count.  In particular, this
+means that the use of C<#!/usr/bin/env perl> will not be changed.
+
+For an explanation of shebang lines, see
+L<http://en.wikipedia.org/wiki/Shebang_%28Unix%29>.
+
+=item have_c_compiler()
+
+[version 0.21]
+
+Returns true if the current system seems to have a working C compiler.
+We currently determine this by attempting to compile a simple C source
+file and reporting whether the attempt was successful.
+
+=item install_base_relpaths()
+
+=item install_base_relpaths($type)
+
+=item install_base_relpaths($type => $path)
+
+[version 0.28]
+
+Set or retrieve the relative paths that are appended to
+C<install_base> for any installable element. This is useful if you
+want to set the relative install path for custom build elements.
+
+With no argument, it returns a reference to a hash containing all
+elements and their respective values. This hash should not be modified
+directly; use the multiple argument below form to change values.
+
+The single argument form returns the value associated with the
+element C<$type>.
+
+The multiple argument form allows you to set the paths for element types.
+C<$value> must be a relative path using Unix-like paths.  (A series of
+directories separated by slashes, e.g. C<foo/bar>.)  The return value is a
+localized path based on C<$value>.
+
+Assigning the value C<undef> to an element causes it to be removed.
+
+=item install_destination($type)
+
+[version 0.28]
+
+Returns the directory in which items of type C<$type> (e.g. C<lib>,
+C<arch>, C<bin>, or anything else returned by the L</install_types()>
+method) will be installed during the C<install> action.  Any settings
+for C<install_path>, C<install_base>, and C<prefix> are taken into
+account when determining the return value.
+
+=item install_path()
+
+=item install_path($type)
+
+=item install_path($type => $path)
+
+[version 0.28]
+
+Set or retrieve paths for specific installable elements. This is
+useful when you want to examine any explicit install paths specified
+by the user on the command line, or if you want to set the install
+path for a specific installable element based on another attribute
+like C<install_base()>.
+
+With no argument, it returns a reference to a hash containing all
+elements and their respective values. This hash should not be modified
+directly; use the multiple argument below form to change values.
+
+The single argument form returns the value associated with the
+element C<$type>.
+
+The multiple argument form allows you to set the paths for element types.
+The supplied C<$path> should be an absolute path to install elements
+of C<$type>.  The return value is C<$path>.
+
+Assigning the value C<undef> to an element causes it to be removed.
+
+=item install_types()
+
+[version 0.28]
+
+Returns a list of installable types that this build knows about.
+These types each correspond to the name of a directory in F<blib/>,
+and the list usually includes items such as C<lib>, C<arch>, C<bin>,
+C<script>, C<libdoc>, C<bindoc>, and if HTML documentation is to be
+built, C<libhtml> and C<binhtml>.  Other user-defined types may also
+exist.
+
+=item invoked_action()
+
+[version 0.28]
+
+This is the name of the original action invoked by the user.  This
+value is set when the user invokes F<Build.PL>, the F<Build> script,
+or programmatically through the L<dispatch()|/"dispatch($action, %args)">
+method.  It does not change as sub-actions are executed as
+dependencies are evaluated.
+
+To get the name of the currently executing dependency, see
+L</current_action()> above.
+
+=item notes()
+
+=item notes($key)
+
+=item notes($key => $value)
+
+[version 0.20]
+
+The C<notes()> value allows you to store your own persistent
+information about the build, and to share that information among
+different entities involved in the build.  See the example in the
+C<current()> method.
+
+The C<notes()> method is essentially a glorified hash access.  With no
+arguments, C<notes()> returns the entire hash of notes.  With one argument,
+C<notes($key)> returns the value associated with the given key.  With two
+arguments, C<notes($key, $value)> sets the value associated with the given key
+to C<$value> and returns the new value.
+
+The lifetime of the C<notes> data is for "a build" - that is, the
+C<notes> hash is created when C<perl Build.PL> is run (or when the
+C<new()> method is run, if the Module::Build Perl API is being used
+instead of called from a shell), and lasts until C<perl Build.PL> is
+run again or the C<clean> action is run.
+
+=item orig_dir()
+
+[version 0.28]
+
+Returns a string containing the working directory that was in effect
+before the F<Build> script chdir()-ed into the C<base_dir>.  This
+might be useful for writing wrapper tools that might need to chdir()
+back out.
+
+=item os_type()
+
+[version 0.04]
+
+If you're subclassing Module::Build and some code needs to alter its
+behavior based on the current platform, you may only need to know
+whether you're running on Windows, Unix, MacOS, VMS, etc., and not the
+fine-grained value of Perl's C<$^O> variable.  The C<os_type()> method
+will return a string like C<Windows>, C<Unix>, C<MacOS>, C<VMS>, or
+whatever is appropriate.  If you're running on an unknown platform, it
+will return C<undef> - there shouldn't be many unknown platforms
+though.
+
+=item is_vmsish()
+
+=item is_windowsish()
+
+=item is_unixish()
+
+Convenience functions that return a boolean value indicating whether
+this platform behaves respectively like VMS, Windows, or Unix.  For
+arbitrary reasons other platforms don't get their own such functions,
+at least not yet.
+
+
+=item prefix_relpaths()
+
+=item prefix_relpaths($installdirs)
+
+=item prefix_relpaths($installdirs, $type)
+
+=item prefix_relpaths($installdirs, $type => $path)
+
+[version 0.28]
+
+Set or retrieve the relative paths that are appended to C<prefix> for
+any installable element.  This is useful if you want to set the
+relative install path for custom build elements.
+
+With no argument, it returns a reference to a hash containing all
+elements and their respective values as defined by the current
+C<installdirs> setting.
+
+With a single argument, it returns a reference to a hash containing
+all elements and their respective values as defined by
+C<$installdirs>.
+
+The hash returned by the above calls should not be modified directly;
+use the three-argument below form to change values.
+
+The two argument form returns the value associated with the
+element C<$type>.
+
+The multiple argument form allows you to set the paths for element types.
+C<$value> must be a relative path using Unix-like paths.  (A series of
+directories separated by slashes, e.g. C<foo/bar>.)  The return value is a
+localized path based on C<$value>.
+
+Assigning the value C<undef> to an element causes it to be removed.
+
+=item get_metadata()
+
+[version 0.36]
+
+This method returns a hash reference of metadata that can be used to create a
+YAML datastream. It is provided for authors to override or customize the fields
+of F<META.yml>.   E.g.
+
+  package My::Builder;
+  use base 'Module::Build';
+
+  sub get_metadata {
+    my $self, @args = @_;
+    my $data = $self->SUPER::get_metadata(@args);
+    $data->{custom_field} = 'foo';
+    return $data;
+  }
+
+The only valid argument is C<fatal>, which indicates whether missing required
+metadata fields should be a fatal error or not.  For META creation, it
+generally should, but for MYMETA creation for end-users, it should not be
+fatal.
+
+This method is a wrapper around the old prepare_metadata API now that we
+no longer use YAML::Node to hold metadata.
+
+=item prepare_metadata() [deprecated]
+
+[version 0.36]
+
+[Deprecated] As of 0.36, authors should use C<get_metadata> instead.  This
+method is preserved for backwards compatibility only.
+
+It takes three positional arguments: a hashref (to which metadata will be
+added), an optional arrayref (to which metadata keys will be added in order if
+the arrayref exists), and a hashref of arguments (as provided to get_metadata).
+The latter argument is new as of 0.36.  Earlier versions are always fatal on
+errors.
+
+Prior to version 0.36, this method took a YAML::Node as an argument to hold
+assembled metadata.
+
+=item prereq_failures()
+
+[version 0.11]
+
+Returns a data structure containing information about any failed
+prerequisites (of any of the types described above), or C<undef> if
+all prerequisites are met.
+
+The data structure returned is a hash reference.  The top level keys
+are the type of prerequisite failed, one of "requires",
+"build_requires", "conflicts", or "recommends".  The associated values
+are hash references whose keys are the names of required (or
+conflicting) modules.  The associated values of those are hash
+references indicating some information about the failure.  For example:
+
+  {
+   have => '0.42',
+   need => '0.59',
+   message => 'Version 0.42 is installed, but we need version 0.59',
+  }
+
+or
+
+  {
+   have => '<none>',
+   need => '0.59',
+   message => 'Prerequisite Foo isn't installed',
+  }
+
+This hash has the same structure as the hash returned by the
+C<check_installed_status()> method, except that in the case of
+"conflicts" dependencies we change the "need" key to "conflicts" and
+construct a proper message.
+
+Examples:
+
+  # Check a required dependency on Foo::Bar
+  if ( $build->prereq_failures->{requires}{Foo::Bar} ) { ...
+
+  # Check whether there were any failures
+  if ( $build->prereq_failures ) { ...
+
+  # Show messages for all failures
+  my $failures = $build->prereq_failures;
+  while (my ($type, $list) = each %$failures) {
+    while (my ($name, $hash) = each %$list) {
+      print "Failure for $name: $hash->{message}\n";
+    }
+  }
+
+=item prereq_data()
+
+[version 0.32]
+
+Returns a reference to a hash describing all prerequisites.  The keys of the
+hash will the various prerequisite types ('requires', 'build_requires',
+'configure_requires', 'recommends', or 'conflicts') and the values will
+references to hashes of module names and version numbers.  Only prerequisites
+types that are defined will be included.  The C<prereq_data> action is just a
+thin wrapper around the C<prereq_data()> method and dumps the hash as a string
+that can be loaded using C<eval()>.
+
+=item prereq_report()
+
+[version 0.28]
+
+Returns a human-readable (table-form) string showing all
+prerequisites, the versions required, and the versions actually
+installed.  This can be useful for reviewing the configuration of your
+system prior to a build, or when compiling data to send for a bug
+report.  The C<prereq_report> action is just a thin wrapper around the
+C<prereq_report()> method.
+
+=item prompt($message, $default)
+
+[version 0.12]
+
+Asks the user a question and returns their response as a string.  The
+first argument specifies the message to display to the user (for
+example, C<"Where do you keep your money?">).  The second argument,
+which is optional, specifies a default answer (for example,
+C<"wallet">).  The user will be asked the question once.
+
+If C<prompt()> detects that it is not running interactively and there
+is nothing on STDIN or if the PERL_MM_USE_DEFAULT environment variable
+is set to true, the $default will be used without prompting.
+
+To prevent automated processes from blocking, the user must either set
+PERL_MM_USE_DEFAULT or attach something to STDIN (this can be a
+pipe/file containing a scripted set of answers or /dev/null.)
+
+If no $default is provided an empty string will be used instead.  In
+non-interactive mode, the absence of $default is an error (though
+explicitly passing C<undef()> as the default is valid as of 0.27.)
+
+This method may be called as a class or object method.
+
+=item recommends()
+
+[version 0.21]
+
+Returns a hash reference indicating the C<recommends> prerequisites
+that were passed to the C<new()> method.
+
+=item requires()
+
+[version 0.21]
+
+Returns a hash reference indicating the C<requires> prerequisites that
+were passed to the C<new()> method.
+
+=item rscan_dir($dir, $pattern)
+
+[version 0.28]
+
+Uses C<File::Find> to traverse the directory C<$dir>, returning a
+reference to an array of entries matching C<$pattern>.  C<$pattern>
+may either be a regular expression (using C<qr//> or just a plain
+string), or a reference to a subroutine that will return true for
+wanted entries.  If C<$pattern> is not given, all entries will be
+returned.
+
+Examples:
+
+ # All the *.pm files in lib/
+ $m->rscan_dir('lib', qr/\.pm$/)
+
+ # All the files in blib/ that aren't *.html files
+ $m->rscan_dir('blib', sub {-f $_ and not /\.html$/});
+
+ # All the files in t/
+ $m->rscan_dir('t');
+
+=item runtime_params()
+
+=item runtime_params($key)
+
+[version 0.28]
+
+The C<runtime_params()> method stores the values passed on the command line
+for valid properties (that is, any command line options for which
+C<valid_property()> returns a true value).  The value on the command line may
+override the default value for a property, as well as any value specified in a
+call to C<new()>.  This allows you to programmatically tell if C<perl Build.PL>
+or any execution of C<./Build> had command line options specified that
+override valid properties.
+
+The C<runtime_params()> method is essentially a glorified read-only hash.  With
+no arguments, C<runtime_params()> returns the entire hash of properties
+specified on the command line.  With one argument, C<runtime_params($key)>
+returns the value associated with the given key.
+
+The lifetime of the C<runtime_params> data is for "a build" - that is, the
+C<runtime_params> hash is created when C<perl Build.PL> is run (or when the
+C<new()> method is called, if the Module::Build Perl API is being used instead
+of called from a shell), and lasts until C<perl Build.PL> is run again or the
+C<clean> action is run.
+
+=item script_files()
+
+[version 0.18]
+
+Returns a hash reference whose keys are the perl script files to be
+installed, if any.  This corresponds to the C<script_files> parameter to the
+C<new()> method.  With an optional argument, this parameter may be set
+dynamically.
+
+For backward compatibility, the C<scripts()> method does exactly the
+same thing as C<script_files()>.  C<scripts()> is deprecated, but it
+will stay around for several versions to give people time to
+transition.
+
+=item up_to_date($source_file, $derived_file)
+
+=item up_to_date(\@source_files, \@derived_files)
+
+[version 0.20]
+
+This method can be used to compare a set of source files to a set of
+derived files.  If any of the source files are newer than any of the
+derived files, it returns false.  Additionally, if any of the derived
+files do not exist, it returns false.  Otherwise it returns true.
+
+The arguments may be either a scalar or an array reference of file
+names.
+
+=item y_n($message, $default)
+
+[version 0.12]
+
+Asks the user a yes/no question using C<prompt()> and returns true or
+false accordingly.  The user will be asked the question repeatedly
+until they give an answer that looks like "yes" or "no".
+
+The first argument specifies the message to display to the user (for
+example, C<"Shall I invest your money for you?">), and the second
+argument specifies the default answer (for example, C<"y">).
+
+Note that the default is specified as a string like C<"y"> or C<"n">,
+and the return value is a Perl boolean value like 1 or 0.  I thought
+about this for a while and this seemed like the most useful way to do
+it.
+
+This method may be called as a class or object method.

+=head1 NAME
+
+Module::Build::Authoring - Authoring Module::Build modules
+
+
+=head1 DESCRIPTION
+
+When creating a C<Build.PL> script for a module, something like the
+following code will typically be used:
+
+  use Module::Build;
+  my $build = Module::Build->new
+    (
+     module_name => 'Foo::Bar',
+     license  => 'perl',
+     requires => {
+                  'perl'          => '5.6.1',
+                  'Some::Module'  => '1.23',
+                  'Other::Module' => '>= 1.2, != 1.5, < 2.0',
+                 },
+    );
+  $build->create_build_script;
+
+A simple module could get away with something as short as this for its
+C<Build.PL> script:
+
+  use Module::Build;
+  Module::Build->new(
+    module_name => 'Foo::Bar',
+    license     => 'perl',
+  )->create_build_script;
+
+The model used by C<Module::Build> is a lot like the C<MakeMaker>
+metaphor, with the following correspondences:
+
+   In Module::Build                 In ExtUtils::MakeMaker
+  ---------------------------      ------------------------
+   Build.PL (initial script)        Makefile.PL (initial script)
+   Build (a short perl script)      Makefile (a long Makefile)
+   _build/ (saved state info)       various config text in the Makefile
+
+Any customization can be done simply by subclassing C<Module::Build>
+and adding a method called (for example) C<ACTION_test>, overriding
+the default 'test' action.  You could also add a method called
+C<ACTION_whatever>, and then you could perform the action C<Build
+whatever>.
+
+For information on providing compatibility with
+C<ExtUtils::MakeMaker>, see L<Module::Build::Compat> and
+L<http://www.makemaker.org/wiki/index.cgi?ModuleBuildConversionGuide>.
+
+
+=head1 STRUCTURE
+
+Module::Build creates a class hierarchy conducive to customization.
+Here is the parent-child class hierarchy in classy ASCII art:
+
+   /--------------------\
+   |   Your::Parent     |  (If you subclass Module::Build)
+   \--------------------/
+            |
+            |
+   /--------------------\  (Doesn't define any functionality
+   |   Module::Build    |   of its own - just figures out what
+   \--------------------/   other modules to load.)
+            |
+            |
+   /-----------------------------------\  (Some values of $^O may
+   |   Module::Build::Platform::$^O    |   define specialized functionality.
+   \-----------------------------------/   Otherwise it's ...::Default, a
+            |                              pass-through class.)
+            |
+   /--------------------------\
+   |   Module::Build::Base    |  (Most of the functionality of 
+   \--------------------------/   Module::Build is defined here.)
+
+
+=head1 SUBCLASSING
+
+Right now, there are two ways to subclass Module::Build.  The first
+way is to create a regular module (in a C<.pm> file) that inherits
+from Module::Build, and use that module's class instead of using
+Module::Build directly:
+
+  ------ in Build.PL: ----------
+  #!/usr/bin/perl
+
+  use lib q(/nonstandard/library/path);
+  use My::Builder;  # Or whatever you want to call it
+
+  my $build = My::Builder->new
+    (
+     module_name => 'Foo::Bar',  # All the regular args...
+     license     => 'perl',
+     dist_author => 'A N Other <me@here.net.au>',
+     requires    => { Carp => 0 }
+    );
+  $build->create_build_script;
+
+This is relatively straightforward, and is the best way to do things
+if your My::Builder class contains lots of code.  The
+C<create_build_script()> method will ensure that the current value of
+C<@INC> (including the C</nonstandard/library/path>) is propagated to
+the Build script, so that My::Builder can be found when running build
+actions.  If you find that you need to C<chdir> into a different directories
+in your subclass methods or actions, be sure to always return to the original
+directory (available via the C<base_dir()> method before returning control
+to the parent class.  This is important to avoid data serialization problems.
+
+For very small additions, Module::Build provides a C<subclass()>
+method that lets you subclass Module::Build more conveniently, without
+creating a separate file for your module:
+
+  ------ in Build.PL: ----------
+  #!/usr/bin/perl
+
+  use Module::Build;
+  my $class = Module::Build->subclass
+    (
+     class => 'My::Builder',
+     code => q{
+       sub ACTION_foo {
+         print "I'm fooing to death!\n";
+       }
+     },
+    );
+
+  my $build = $class->new
+    (
+     module_name => 'Foo::Bar',  # All the regular args...
+     license     => 'perl',
+     dist_author => 'A N Other <me@here.net.au>',
+     requires    => { Carp => 0 }
+    );
+  $build->create_build_script;
+
+Behind the scenes, this actually does create a C<.pm> file, since the
+code you provide must persist after Build.PL is run if it is to be
+very useful.
+
+See also the documentation for the L<Module::Build::API/"subclass()">
+method.
+
+
+=head1 PREREQUISITES
+
+=head2 Types of prerequisites
+
+To specify what versions of other modules are used by this
+distribution, several types of prerequisites can be defined with the
+following parameters:
+
+=over 3
+
+=item configure_requires
+
+Items that must be installed I<before> configuring this distribution
+(i.e. before running the F<Build.PL> script).  This might be a
+specific minimum version of C<Module::Build> or any other module the
+F<Build.PL> needs in order to do its stuff.  Clients like C<CPAN.pm>
+or C<CPANPLUS> will be expected to pick C<configure_requires> out of the
+F<META.yml> file and install these items before running the
+C<Build.PL>.
+
+If no configure_requires is specified, the current version of Module::Build
+is automatically added to configure_requires.
+
+=item build_requires
+
+Items that are necessary for building and testing this distribution,
+but aren't necessary after installation.  This can help users who only
+want to install these items temporarily.  It also helps reduce the
+size of the CPAN dependency graph if everything isn't smooshed into
+C<requires>.
+
+=item requires
+
+Items that are necessary for basic functioning.
+
+=item recommends
+
+Items that are recommended for enhanced functionality, but there are
+ways to use this distribution without having them installed.  You
+might also think of this as "can use" or "is aware of" or "changes
+behavior in the presence of".
+
+=item conflicts
+
+Items that can cause problems with this distribution when installed.
+This is pretty rare.
+
+=back
+
+=head2 Format of prerequisites
+
+The prerequisites are given in a hash reference, where the keys are
+the module names and the values are version specifiers:
+
+  requires => {
+               Foo::Module => '2.4',
+               Bar::Module => 0,
+               Ken::Module => '>= 1.2, != 1.5, < 2.0',
+               perl => '5.6.0'
+              },
+
+The above four version specifiers have different effects.  The value
+C<'2.4'> means that B<at least> version 2.4 of C<Foo::Module> must be
+installed.  The value C<0> means that B<any> version of C<Bar::Module>
+is acceptable, even if C<Bar::Module> doesn't define a version.  The
+more verbose value C<'E<gt>= 1.2, != 1.5, E<lt> 2.0'> means that
+C<Ken::Module>'s version must be B<at least> 1.2, B<less than> 2.0,
+and B<not equal to> 1.5.  The list of criteria is separated by commas,
+and all criteria must be satisfied.
+
+A special C<perl> entry lets you specify the versions of the Perl
+interpreter that are supported by your module.  The same version
+dependency-checking semantics are available, except that we also
+understand perl's new double-dotted version numbers.
+
+=head2 XS Extensions
+
+Modules which need to compile XS code should list C<ExtUtils::CBuilder>
+as a C<build_requires> element.
+
+
+=head1 SAVING CONFIGURATION INFORMATION
+
+Module::Build provides a very convenient way to save configuration
+information that your installed modules (or your regression tests) can
+access.  If your Build process calls the C<feature()> or
+C<config_data()> methods, then a C<Foo::Bar::ConfigData> module will
+automatically be created for you, where C<Foo::Bar> is the
+C<module_name> parameter as passed to C<new()>.  This module provides
+access to the data saved by these methods, and a way to update the
+values.  There is also a utility script called C<config_data>
+distributed with Module::Build that provides a command line interface
+to this same functionality.  See also the generated
+C<Foo::Bar::ConfigData> documentation, and the C<config_data>
+script's documentation, for more information.
+
+
+=head1 STARTING MODULE DEVELOPMENT
+
+When starting development on a new module, it's rarely worth your time
+to create a tree of all the files by hand.  Some automatic
+module-creators are available: the oldest is C<h2xs>, which has
+shipped with perl itself for a long time.  Its name reflects the fact
+that modules were originally conceived of as a way to wrap up a C
+library (thus the C<h> part) into perl extensions (thus the C<xs>
+part).
+
+These days, C<h2xs> has largely been superseded by modules like
+C<ExtUtils::ModuleMaker>, and C<Module::Starter>.  They have varying
+degrees of support for C<Module::Build>.
+
+
+=head1 AUTOMATION
+
+One advantage of Module::Build is that since it's implemented as Perl
+methods, you can invoke these methods directly if you want to install
+a module non-interactively.  For instance, the following Perl script
+will invoke the entire build/install procedure:
+
+  my $build = Module::Build->new(module_name => 'MyModule');
+  $build->dispatch('build');
+  $build->dispatch('test');
+  $build->dispatch('install');
+
+If any of these steps encounters an error, it will throw a fatal
+exception.
+
+You can also pass arguments as part of the build process:
+
+  my $build = Module::Build->new(module_name => 'MyModule');
+  $build->dispatch('build');
+  $build->dispatch('test', verbose => 1);
+  $build->dispatch('install', sitelib => '/my/secret/place/');
+
+Building and installing modules in this way skips creating the
+C<Build> script.
+
+
+=head1 MIGRATION
+
+Note that if you want to provide both a F<Makefile.PL> and a
+F<Build.PL> for your distribution, you probably want to add the
+following to C<WriteMakefile> in your F<Makefile.PL> so that C<MakeMaker>
+doesn't try to run your F<Build.PL> as a normal F<.PL> file:
+
+  PL_FILES => {},
+
+You may also be interested in looking at the C<Module::Build::Compat>
+module, which can automatically create various kinds of F<Makefile.PL>
+compatibility layers.

+
+=head1 DESCRIPTION
+
+The C<Module::Build::Base> module defines the core functionality of
+C<Module::Build>.  Its methods may be overridden by any of the
+platform-dependent modules in the C<Module::Build::Platform::>
+namespace, but the intention here is to make this base module as
+platform-neutral as possible.  Nicely enough, Perl has several core
+tools available in the C<File::> namespace for doing this, so the task
+isn't very difficult.
+
+Please see the C<Module::Build> documentation for more details.

+=head1 NAME
+
+Module::Build::Bundling - How to bundle Module::Build with a distribution
+
+=head1 SYNOPSIS
+
+  # Build.PL
+  use inc::latest 'Module::Build';
+
+  Module::Build->new(
+    module_name => 'Foo::Bar',
+    license => 'perl',
+  )->create_build_script;
+
+=head1 DESCRIPTION
+
+B<WARNING -- THIS IS AN EXPERIMENTAL FEATURE>
+
+In order to install a distribution using Module::Build, users must
+have Module::Build available on their systems.  There are two ways
+to do this.  The first way is to include Module::Build in the
+C<configure_requires> metadata field.  This field is supported by
+recent versions L<CPAN> and L<CPANPLUS> and is a standard feature
+in the Perl core as of Perl 5.10.1.  Module::Build now adds itself
+to C<configure_requires> by default.
+
+The second way supports older Perls that have not upgraded CPAN or
+CPANPLUS and involves bundling an entire copy of Module::Build
+into the distribution's C<inc/> directory.  This is the same approach
+used by L<Module::Install>, a modern wrapper around ExtUtils::MakeMaker
+for Makefile.PL based distributions.
+
+The "trick" to making this work for Module::Build is making sure the
+highest version Module::Build is used, whether this is in C<inc/> or
+already installed on the user's system.  This ensures that all necessary
+features are available as well as any new bug fixes.  This is done using
+the new L<inc::latest> module.
+
+A "normal" Build.PL looks like this (with only the minimum required
+fields):
+
+  use Module::Build;
+
+  Module::Build->new(
+    module_name => 'Foo::Bar',
+    license     => 'perl',
+  )->create_build_script;
+
+A "bundling" Build.PL replaces the initial "use" line with a nearly
+transparent replacement:
+
+  use inc::latest 'Module::Build';
+
+  Module::Build->new(
+    module_name => 'Foo::Bar',
+    license => 'perl',
+  )->create_build_script;
+
+For I<authors>, when "Build dist" is run, Module::Build will be
+automatically bundled into C<inc> according to the rules for
+L<inc::latest>.
+
+For I<users>, inc::latest will load the latest Module::Build, whether
+installed or bundled in C<inc/>.
+
+=head1 BUNDLING OTHER CONFIGURATION DEPENDENCIES
+
+The same approach works for other configuration dependencies -- modules
+that I<must> be available for Build.PL to run.  All other dependencies can
+be specified as usual in the Build.PL and CPAN or CPANPLUS will install
+them after Build.PL finishes.
+
+For example, to bundle the L<Devel::AssertOS::Unix> module (which ensures a
+"Unix-like" operating system), one could do this:
+
+  use inc::latest 'Devel::AssertOS::Unix';
+  use inc::latest 'Module::Build';
+
+  Module::Build->new(
+    module_name => 'Foo::Bar',
+    license => 'perl',
+  )->create_build_script;
+
+The C<inc::latest> module creates bundled directories based on the packlist
+file of an installed distribution.  Even though C<inc::latest> takes module
+name arguments, it is better to think of it as bundling and making
+available entire I<distributions>.  When a module is loaded through
+C<inc::latest>, it looks in all bundled distributions in C<inc/> for a
+newer module than can be found in the existing C<@INC> array.
+
+Thus, the module-name provided should usually be the "top-level" module
+name of a distribution, though this is not strictly required.  For example,
+L<Module::Build> has a number of heuristics to map module names to
+packlists, allowing users to do things like this:
+
+  use inc::latest 'Devel::AssertOS::Unix';
+
+even though Devel::AssertOS::Unix is contained within the Devel-CheckOS
+distribution.
+
+At the current time, packlists are required.  Thus, bundling dual-core
+modules, I<including Module::Build>, may require a 'forced install' over
+versions in the latest version of perl in order to create the necessary
+packlist for bundling.  This limitation will hopefully be addressed in a
+future version of Module::Build.
+
+=head2 WARNING -- How to Manage Dependency Chains
+
+Before bundling a distribution you must ensure that all prerequisites are
+also bundled and load in the correct order.  For Module::Build itself, this
+should not be necessary, but it is necessary for any other distribution.
+(A future release of Module::Build will hopefully address this deficiency.)
+
+For example, if you need C<Wibble>, but C<Wibble> depends on C<Wobble>,
+your Build.PL might look like this:
+
+  use inc::latest 'Wobble';
+  use inc::latest 'Wibble';
+  use inc::latest 'Module::Build';
+
+  Module::Build->new(
+    module_name => 'Foo::Bar',
+    license => 'perl',
+  )->create_build_script;
+
+Authors are strongly suggested to limit the bundling of additional
+dependencies if at all possible and to carefully test their distribution
+tarballs on older versions of Perl before uploading to CPAN.

+=head1 NAME
+
+Module::Build::Compat - Compatibility with ExtUtils::MakeMaker
+
+
+=head1 SYNOPSIS
+
+  # In a Build.PL :
+  use Module::Build;
+  my $build = Module::Build->new
+    ( module_name => 'Foo::Bar',
+      license     => 'perl',
+      create_makefile_pl => 'traditional' );
+  ...
+
+
+=head1 DESCRIPTION
+
+Because C<ExtUtils::MakeMaker> has been the standard way to distribute
+modules for a long time, many tools (CPAN.pm, or your system
+administrator) may expect to find a working F<Makefile.PL> in every
+distribution they download from CPAN.  If you want to throw them a
+bone, you can use C<Module::Build::Compat> to automatically generate a
+F<Makefile.PL> for you, in one of several different styles.
+
+C<Module::Build::Compat> also provides some code that helps out the
+F<Makefile.PL> at runtime.
+
+
+=head1 METHODS
+
+=over 4
+
+=item create_makefile_pl($style, $build)
+
+Creates a F<Makefile.PL> in the current directory in one of several
+styles, based on the supplied C<Module::Build> object C<$build>.  This is
+typically controlled by passing the desired style as the
+C<create_makefile_pl> parameter to C<Module::Build>'s C<new()> method;
+the F<Makefile.PL> will then be automatically created during the
+C<distdir> action.
+
+The currently supported styles are:
+
+=over 4
+
+=item traditional
+
+A F<Makefile.PL> will be created in the "traditional" style, i.e. it will
+use C<ExtUtils::MakeMaker> and won't rely on C<Module::Build> at all.
+In order to create the F<Makefile.PL>, we'll include the C<requires> and
+C<build_requires> dependencies as the C<PREREQ_PM> parameter.
+
+You don't want to use this style if during the C<perl Build.PL> stage
+you ask the user questions, or do some auto-sensing about the user's
+environment, or if you subclass C<Module::Build> to do some
+customization, because the vanilla F<Makefile.PL> won't do any of that.
+
+=item small
+
+A small F<Makefile.PL> will be created that passes all functionality
+through to the F<Build.PL> script in the same directory.  The user must
+already have C<Module::Build> installed in order to use this, or else
+they'll get a module-not-found error.
+
+=item passthrough (DEPRECATED)
+
+This is just like the C<small> option above, but if C<Module::Build> is
+not already installed on the user's system, the script will offer to
+use C<CPAN.pm> to download it and install it before continuing with
+the build.
+
+This option has been deprecated and may be removed in a future version
+of Module::Build.  Modern CPAN.pm and CPANPLUS will recognize the
+C<configure_requires> metadata property and install Module::Build before
+running Build.PL if Module::Build is listed and Module::Build now
+adds itself to configure_requires by default.
+
+Perl 5.10.1 includes C<configure_requires> support.  In the future, when
+C<configure_requires> support is deemed sufficiently widespread, the
+C<passthrough> style will be removed.
+
+=back
+
+=item run_build_pl(args => \@ARGV)
+
+This method runs the F<Build.PL> script, passing it any arguments the
+user may have supplied to the C<perl Makefile.PL> command.  Because
+C<ExtUtils::MakeMaker> and C<Module::Build> accept different arguments, this
+method also performs some translation between the two.
+
+C<run_build_pl()> accepts the following named parameters:
+
+=over 4
+
+=item args
+
+The C<args> parameter specifies the parameters that would usually
+appear on the command line of the C<perl Makefile.PL> command -
+typically you'll just pass a reference to C<@ARGV>.
+
+=item script
+
+This is the filename of the script to run - it defaults to C<Build.PL>.
+
+=back
+
+=item write_makefile()
+
+This method writes a 'dummy' F<Makefile> that will pass all commands
+through to the corresponding C<Module::Build> actions.
+
+C<write_makefile()> accepts the following named parameters:
+
+=over 4
+
+=item makefile
+
+The name of the file to write - defaults to the string C<Makefile>.

+=item 1.
+
+Just include a F<Build.PL> script (without a F<Makefile.PL>
+script), and give installation directions in a F<README> or F<INSTALL>
+document explaining how to install the module.  In particular, explain
+that the user must install C<Module::Build> before installing your
+module.
+
+Note that if you do this, you may make things easier for yourself, but
+harder for people with older versions of CPAN or CPANPLUS on their
+system, because those tools generally only understand the
+F<Makefile.PL>/C<ExtUtils::MakeMaker> way of doing things.
+
+=item 2.
+
+Include a F<Build.PL> script and a "traditional" F<Makefile.PL>,
+created either manually or with C<create_makefile_pl()>.  Users won't
+ever have to install C<Module::Build> if they use the F<Makefile.PL>, but
+they won't get to take advantage of C<Module::Build>'s extra features
+either.
+
+For good measure, of course, test both the F<Makefile.PL> and the
+F<Build.PL> before shipping.
+
+=item 3.
+
+Include a F<Build.PL> script and a "pass-through" F<Makefile.PL>
+built using C<Module::Build::Compat>.  This will mean that people can
+continue to use the "old" installation commands, and they may never
+notice that it's actually doing something else behind the scenes.  It
+will also mean that your installation process is compatible with older
+versions of tools like CPAN and CPANPLUS.

+=head1 NAME
+
+Module::Build::ConfigData - Configuration for Module::Build
+
+=head1 SYNOPSIS
+
+  use Module::Build::ConfigData;
+  $value = Module::Build::ConfigData->config('foo');
+  $value = Module::Build::ConfigData->feature('bar');
+
+  @names = Module::Build::ConfigData->config_names;
+  @names = Module::Build::ConfigData->feature_names;
+
+  Module::Build::ConfigData->set_config(foo => $new_value);
+  Module::Build::ConfigData->set_feature(bar => $new_value);
+  Module::Build::ConfigData->write;  # Save changes
+
+
+=head1 DESCRIPTION
+
+This module holds the configuration data for the C<Module::Build>
+module.  It also provides a programmatic interface for getting or
+setting that configuration data.  Note that in order to actually make
+changes, you'll have to have write access to the C<Module::Build::ConfigData>
+module, and you should attempt to understand the repercussions of your
+actions.
+
+
+=head1 METHODS
+
+=over 4
+
+=item config($name)
+
+Given a string argument, returns the value of the configuration item
+by that name, or C<undef> if no such item exists.

+name, or C<undef> if no such feature exists.
+
+=item set_config($name, $value)
+
+Sets the configuration item with the given name to the given value.
+The value may be any Perl scalar that will serialize correctly using
+C<Data::Dumper>.  This includes references, objects (usually), and
+complex data structures.  It probably does not include transient
+things like filehandles or sockets.

+
+
+=head1 NAME
+
+Module::Build::Cookbook - Examples of Module::Build Usage
+
+=head1 DESCRIPTION
+
+C<Module::Build> isn't conceptually very complicated, but examples are
+always helpful.  The following recipes should help developers and/or
+installers put together the pieces from the other parts of the
+documentation.
+
+
+=head1 BASIC RECIPES
+
+
+=head2 Installing modules that use Module::Build
+
+In most cases, you can just issue the following commands:
+
+  perl Build.PL
+  ./Build
+  ./Build test
+  ./Build install
+
+There's nothing complicated here - first you're running a script
+called F<Build.PL>, then you're running a (newly-generated) script
+called F<Build> and passing it various arguments.
+
+The exact commands may vary a bit depending on how you invoke perl
+scripts on your system.  For instance, if you have multiple versions
+of perl installed, you can install to one particular perl's library
+directories like so:
+
+  /usr/bin/perl5.8.1 Build.PL
+  ./Build
+  ./Build test
+  ./Build install
+
+If you're on Windows where the current directory is always searched
+first for scripts, you'll probably do something like this:
+
+  perl Build.PL
+  Build
+  Build test
+  Build install
+
+On the old Mac OS (version 9 or lower) using MacPerl, you can
+double-click on the F<Build.PL> script to create the F<Build> script,
+then double-click on the F<Build> script to run its C<build>, C<test>,
+and C<install> actions.
+
+The F<Build> script knows what perl was used to run F<Build.PL>, so
+you don't need to re-invoke the F<Build> script with the complete perl
+path each time.  If you invoke it with the I<wrong> perl path, you'll
+get a warning or a fatal error.
+
+=head2 Modifying Config.pm values
+
+C<Module::Build> relies heavily on various values from perl's
+C<Config.pm> to do its work.  For example, default installation paths
+are given by C<installsitelib> and C<installvendorman3dir> and
+friends, C linker & compiler settings are given by C<ld>,
+C<lddlflags>, C<cc>, C<ccflags>, and so on.  I<If you're pretty sure
+you know what you're doing>, you can tell C<Module::Build> to pretend
+there are different values in F<Config.pm> than what's really there,
+by passing arguments for the C<--config> parameter on the command
+line:
+
+  perl Build.PL --config cc=gcc --config ld=gcc
+
+Inside the C<Build.PL> script the same thing can be accomplished by
+passing values for the C<config> parameter to C<new()>:
+
+ my $build = Module::Build->new
+   (
+    ...
+    config => { cc => 'gcc', ld => 'gcc' },
+    ...
+   );
+
+In custom build code, the same thing can be accomplished by calling
+the L<Module::Build/config> method:
+
+ $build->config( cc => 'gcc' );     # Set
+ $build->config( ld => 'gcc' );     # Set
+ ...
+ my $linker = $build->config('ld'); # Get
+
+
+=head2 Installing modules using the programmatic interface
+
+If you need to build, test, and/or install modules from within some
+other perl code (as opposed to having the user type installation
+commands at the shell), you can use the programmatic interface.
+Create a Module::Build object (or an object of a custom Module::Build
+subclass) and then invoke its C<dispatch()> method to run various
+actions.
+
+  my $build = Module::Build->new
+    (
+     module_name => 'Foo::Bar',
+     license     => 'perl',
+     requires    => { 'Some::Module'   => '1.23' },
+    );
+  $build->dispatch('build');
+  $build->dispatch('test', verbose => 1);
+  $build->dispatch('install');
+
+The first argument to C<dispatch()> is the name of the action, and any
+following arguments are named parameters.
+
+This is the interface we use to test Module::Build itself in the
+regression tests.
+
+
+=head2 Installing to a temporary directory
+
+To create packages for package managers like RedHat's C<rpm> or
+Debian's C<deb>, you may need to install to a temporary directory
+first and then create the package from that temporary installation.
+To do this, specify the C<destdir> parameter to the C<install> action:
+
+  ./Build install --destdir /tmp/my-package-1.003
+
+This essentially just prepends all the installation paths with the
+F</tmp/my-package-1.003> directory.
+
+
+=head2 Installing to a non-standard directory
+
+To install to a non-standard directory (for example, if you don't have
+permission to install in the system-wide directories), you can use the
+C<install_base> or C<prefix> parameters:
+
+  ./Build install --install_base /foo/bar
+
+See L<Module::Build/"INSTALL PATHS"> for a much more complete
+discussion of how installation paths are determined.
+
+
+=head2 Installing in the same location as ExtUtils::MakeMaker
+
+With the introduction of C<--prefix> in Module::Build 0.28 and
+C<INSTALL_BASE> in C<ExtUtils::MakeMaker> 6.31 its easy to get them both
+to install to the same locations.
+
+First, ensure you have at least version 0.28 of Module::Build
+installed and 6.31 of C<ExtUtils::MakeMaker>.  Prior versions have
+differing (and in some cases quite strange) installation behaviors.
+
+The following installation flags are equivalent between
+C<ExtUtils::MakeMaker> and C<Module::Build>.
+
+    MakeMaker             Module::Build
+    PREFIX=...            --prefix ...
+    INSTALL_BASE=...      --install_base ...
+    DESTDIR=...           --destdir ...
+    LIB=...               --install_path lib=...
+    INSTALLDIRS=...       --installdirs ...
+    INSTALLDIRS=perl      --installdirs core
+    UNINST=...            --uninst ...
+    INC=...               --extra_compiler_flags ...
+    POLLUTE=1             --extra_compiler_flags -DPERL_POLLUTE
+
+For example, if you are currently installing C<MakeMaker> modules with
+this command:
+
+    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'},
+     ...other stuff here...
+    );
+  $build->add_build_element('dat');
+  $build->create_build_script;
+
+If your extra files actually need to be created on the user's machine,
+or if they need some other kind of special processing, you'll probably
+want to subclass C<Module::Build> and create a special method to
+process them, named C<process_${kind}_files()>:
+
+  use Module::Build;
+  my $class = Module::Build->subclass(code => <<'EOF');
+    sub process_dat_files {
+      my $self = shift;
+      ... locate and process *.dat files,
+      ... and create something in blib/lib/
+    }
+  EOF
+  my $build = $class->new
+    (
+     module_name => 'Foo::Bar',
+     ...other stuff here...
+    );
+  $build->add_build_element('dat');
+  $build->create_build_script;
+
+If your extra files don't go in F<lib/> but in some other place, see
+L<"Adding new elements to the install process"> for how to actually
+get them installed.
+
+Please note that these examples use some capabilities of Module::Build
+that first appeared in version 0.26.  Before that it could
+still be done, but the simple cases took a bit more work.
+
+
+=head2 Adding new elements to the install process
+
+By default, Module::Build creates seven subdirectories of the F<blib>
+directory during the build process: F<lib>, F<arch>, F<bin>,
+F<script>, F<bindoc>, F<libdoc>, and F<html> (some of these may be
+missing or empty if there's nothing to go in them).  Anything copied
+to these directories during the build will eventually be installed
+during the C<install> action (see L<Module::Build/"INSTALL PATHS">.
+
+If you need to create a new custom type of installable element, e.g. C<conf>,
+then you need to tell Module::Build where things in F<blib/conf/>
+should be installed.  To do this, use the C<install_path> parameter to
+the C<new()> method:
+
+  my $build = Module::Build->new
+    (
+     ...other stuff here...
+     install_path => { conf => $installation_path }
+    );
+
+Or you can call the C<install_path()> method later:
+
+  $build->install_path(conf => $installation_path);
+
+The user may also specify the path on the command line:
+
+  perl Build.PL --install_path conf=/foo/path/etc
+
+The important part, though, is that I<somehow> the install path needs
+to be set, or else nothing in the F<blib/conf/> directory will get
+installed, and a runtime error during the C<install> action will
+result.
+
+See also L<"Adding new file types to the build process"> for how to
+create the stuff in F<blib/conf/> in the first place.
+
+
+=head1 EXAMPLES ON CPAN
+
+Several distributions on CPAN are making good use of various features
+of Module::Build.  They can serve as real-world examples for others.
+
+
+=head2 SVN-Notify-Mirror
+
+L<http://search.cpan.org/~jpeacock/SVN-Notify-Mirror/>
+
+John Peacock, author of the C<SVN-Notify-Mirror> distribution, says:
+
+=over 4
+
+=item 1. Using C<auto_features>, I check to see whether two optional
+modules are available - SVN::Notify::Config and Net::SSH;
+
+=item 2. If the S::N::Config module is loaded, I automatically
+generate test files for it during Build (using the C<PL_files>
+property).
+
+=item 3. If the C<ssh_feature> is available, I ask if the user wishes
+to perform the ssh tests (since it requires a little preliminary
+setup);
+
+=item 4. Only if the user has C<ssh_feature> and answers yes to the
+testing, do I generate a test file.
+
+I'm sure I could not have handled this complexity with EU::MM, but it
+was very easy to do with M::B.
+
+=back
+
+
+=head2 Modifying an action
+
+Sometimes you might need an to have an action, say C<./Build install>,
+do something unusual.  For instance, you might need to change the
+ownership of a file or do something else peculiar to your application.
+
+You can subclass C<Module::Build> on the fly using the C<subclass()>
+method and override the methods that perform the actions.  You may
+need to read through C<Module::Build::Authoring> and
+C<Module::Build::API> to find the methods you want to override.  All
+"action" methods are implemented by a method called "ACTION_" followed
+by the action's name, so here's an example of how it would work for
+the C<install> action:
+
+  # Build.PL
+  use Module::Build;
+  my $class = Module::Build->subclass(
+      class => "Module::Build::Custom",
+      code => <<'SUBCLASS' );
+
+  sub ACTION_install {
+      my $self = shift;
+      # YOUR CODE HERE
+      $self->SUPER::ACTION_install;
+  }
+  SUBCLASS
+
+  $class->new(
+      module_name => 'Your::Module',
+      # rest of the usual Module::Build parameters
+  )->create_build_script;
+
+
+=head2 Adding an action
+
+You can add a new C<./Build> action simply by writing the method for
+it in your subclass.  Use C<depends_on> to declare that another action
+must have been run before your action.
+
+For example, let's say you wanted to be able to write C<./Build
+commit> to test your code and commit it to Subversion.
+
+  # Build.PL
+  use Module::Build;
+  my $class = Module::Build->subclass(
+      class => "Module::Build::Custom",
+      code => <<'SUBCLASS' );
+
+  sub ACTION_commit {
+      my $self = shift;
+
+      $self->depends_on("test");
+      $self->do_system(qw(svn commit));
+  }
+  SUBCLASS
+
+
+=head2 Bundling Module::Build
+
+Note: This section probably needs an update as the technology improves
+(see contrib/bundle.pl in the distribution).
+
+Suppose you want to use some new-ish features of Module::Build,
+e.g. newer than the version of Module::Build your users are likely to
+already have installed on their systems.  The first thing you should
+do is set C<configure_requires> to your minimum version of
+Module::Build.  See L<Module::Build::Authoring>.
+
+But not every build system honors C<configure_requires> yet.  Here's
+how you can ship a copy of Module::Build, but still use a newer
+installed version to take advantage of any bug fixes and upgrades.
+
+First, install Module::Build into F<Your-Project/inc/Module-Build>.
+CPAN will not index anything in the F<inc> directory so this copy will
+not show up in CPAN searches.
+
+    cd Module-Build
+    perl Build.PL --install_base /path/to/Your-Project/inc/Module-Build
+    ./Build test
+    ./Build install
+
+You should now have all the Module::Build .pm files in
+F<Your-Project/inc/Module-Build/lib/perl5>.
+
+Next, add this to the top of your F<Build.PL>.
+
+    my $Bundled_MB = 0.30;  # or whatever version it was.
+
+    # Find out what version of Module::Build is installed or fail quietly.
+    # This should be cross-platform.
+    my $Installed_MB =
+        `$^X -e "eval q{require Module::Build; print Module::Build->VERSION} or exit 1";
+
+    # some operating systems put a newline at the end of every print.
+    chomp $Installed_MB;
+
+    $Installed_MB = 0 if $?;
+
+    # Use our bundled copy of Module::Build if it's newer than the installed.
+    unshift @INC, "inc/Module-Build/lib/perl5" if $Bundled_MB > $Installed_MB;
+
+    require Module::Build;
+
+And write the rest of your F<Build.PL> normally.  Module::Build will
+remember your change to C<@INC> and use it when you run F<./Build>.
+
+In the future, we hope to provide a more automated solution for this
+scenario; see C<inc/latest.pm> in the Module::Build distribution for
+one indication of the direction we're moving.

+=head1 NAME
+
+ModuleInfo - Gather package and POD information from a perl module file
+
+
+=head1 DESCRIPTION
+
+=over 4
+
+=item new_from_file($filename, collect_pod => 1)
+
+Construct a C<ModuleInfo> object given the path to a file. Takes an optional
+argument C<collect_pod> which is a boolean that determines whether
+POD data is collected and stored for reference. POD data is not
+collected by default. POD headings are always collected.
+
+=item new_from_module($module, collect_pod => 1, inc => \@dirs)
+
+Construct a C<ModuleInfo> object given a module or package name. In addition
+to accepting the C<collect_pod> argument as described above, this
+method accepts a C<inc> argument which is a reference to an array of
+of directories to search for the module. If none are given, the
+default is @INC.
+
+=item name()
+
+Returns the name of the package represented by this module. If there
+are more than one packages, it makes a best guess based on the
+filename. If it's a script (i.e. not a *.pm) the package name is
+'main'.
+
+=item version($package)
+
+Returns the version as defined by the $VERSION variable for the
+package as returned by the C<name> method if no arguments are
+given. If given the name of a package it will attempt to return the
+version of that package if it is specified in the file.
+
+=item filename()
+
+Returns the absolute path to the file.
+
+=item packages_inside()
+
+Returns a list of packages.
+
+=item pod_inside()
+
+Returns a list of POD sections.
+
+=item contains_pod()
+
+Returns true if there is any POD in the file.
+
+=item pod($section)
+
+Returns the POD data in the given section.
+
+=item find_module_by_name($module, \@dirs)
+
+Returns the path to a module given the module or package name. A list
+of directories can be passed in as an optional parameter, otherwise
+@INC is searched.
+
+Can be called as either an object or a class method.
+
+=item find_module_dir_by_name($module, \@dirs)
+
+Returns the entry in C<@dirs> (or C<@INC> by default) that contains
+the module C<$module>. A list of directories can be passed in as an
+optional parameter, otherwise @INC is searched.
+
+Can be called as either an object or a class method.

+NOTES_NAME - Configuration for MODULE_NAME
+
+=head1 SYNOPSIS

+  $value = NOTES_NAME->feature('bar');
+
+  @names = NOTES_NAME->config_names;
+  @names = NOTES_NAME->feature_names;

+  NOTES_NAME->set_config(foo => $new_value);
+  NOTES_NAME->set_feature(bar => $new_value);
+  NOTES_NAME->write;  # Save changes
+
+
+=head1 DESCRIPTION
+
+This module holds the configuration data for the C<MODULE_NAME>
+module.  It also provides a programmatic interface for getting or
+setting that configuration data.  Note that in order to actually make
+changes, you'll have to have write access to the C<NOTES_NAME>
+module, and you should attempt to understand the repercussions of your
+actions.
+
+
+=head1 METHODS
+
+=over 4
+
+=item config($name)
+
+Given a string argument, returns the value of the configuration item
+by that name, or C<undef> if no such item exists.
+
+=item feature($name)
+
+Given a string argument, returns the value of the feature by that
+name, or C<undef> if no such feature exists.
+
+=item set_config($name, $value)
+
+Sets the configuration item with the given name to the given value.
+The value may be any Perl scalar that will serialize correctly using
+C<Data::Dumper>.  This includes references, objects (usually), and
+complex data structures.  It probably does not include transient
+things like filehandles or sockets.
+
+=item set_feature($name, $value)
+
+Sets the feature with the given name to the given boolean value.  The
+value will be converted to 0 or 1 automatically.
+
+=item config_names()
+
+Returns a list of all the names of config items currently defined in
+C<NOTES_NAME>, or in scalar context the number of items.
+
+=item feature_names()
+
+Returns a list of all the names of features currently defined in
+C<NOTES_NAME>, or in scalar context the number of features.
+
+=item auto_feature_names()
+
+Returns a list of all the names of features whose availability is
+dynamically determined, or in scalar context the number of such
+features.  Does not include such features that have later been set to
+a fixed value.
+
+=item write()
+
+Commits any changes from C<set_config()> and C<set_feature()> to disk.
+Requires write access to the C<NOTES_NAME> module.

+MacPerl doesn't define $Config{sitelib} or $Config{sitearch} for some

+

+
+On MacOS we set the file type and creator to MacPerl so it will run
+with a double-click.
+
+=item dispatch()
+
+Because there's no easy way to say "./Build test" on MacOS, if
+dispatch is called with no arguments and no @ARGV a dialog box will
+pop up asking what action to take and any extra arguments.
+
+Default action is "test".
