=head1 NAME

Module::Build - Build and install Perl modules

=head1 SYNOPSIS

Standard process for building & installing modules:

  perl Build.PL
  ./Build
  ./Build test
  ./Build install

Or, if you're on a platform (like DOS or Windows) that doesn't require
the "./" notation, you can do this:

  perl Build.PL
  Build
  Build test
  Build install


=head1 DESCRIPTION

C<Module::Build> is a system for building, testing, and installing
Perl modules.  It is meant to be an alternative to
C<ExtUtils::MakeMaker>.  Developers may alter the behavior of the
module through subclassing in a much more straightforward way than
with C<MakeMaker>.  It also does not require a C<make> on your system
- most of the C<Module::Build> code is pure-perl and written in a very
cross-platform way.

See L<"MOTIVATIONS"> for more comparisons between C<ExtUtils::MakeMaker>
and C<Module::Build>.

To install C<Module::Build>, and any other module that uses
C<Module::Build> for its installation process, do the following:

  perl Build.PL       # 'Build.PL' script creates the 'Build' script
  ./Build             # Need ./ to ensure we're using this "Build" script
  ./Build test        # and not another one that happens to be in the PATH
  ./Build install

This illustrates initial configuration and the running of three
'actions'.  In this case the actions run are 'build' (the default
action), 'test', and 'install'.  Other actions defined so far include:

  build                          manifest
  clean                          manifest_skip

Performs the 'realclean' action and then the 'distcheck' action.

=item distdir

[version 0.05]

Creates a "distribution directory" named C<$dist_name-$dist_version>
(if that directory already exists, it will be removed first), then
copies all the files listed in the F<MANIFEST> file to that directory.
This directory is what the distribution tarball is created from.

=item distinstall

[version 0.37]

Performs the 'distdir' action, then switches into that directory and runs a
C<perl Build.PL>, followed by the 'build' and 'install' actions in that
directory.  Use PERL_MB_OPT or F<.modulebuildrc> to set options that should be
applied during subprocesses

=item distmeta

[version 0.21]

Creates the F<META.yml> file that describes the distribution.

F<META.yml> is a file containing various bits of I<metadata> about the
distribution.  The metadata includes the distribution name, version,
abstract, prerequisites, license, and various other data about the
distribution.  This file is created as F<META.yml> in a simplified YAML format.

F<META.yml> file must also be listed in F<MANIFEST> - if it's not, a
warning will be issued.

The current version of the F<META.yml> specification can be found
on CPAN as L<CPAN::Meta::Spec>.

=item distsign

[version 0.16]

Uses C<Module::Signature> to create a SIGNATURE file for your
distribution, and adds the SIGNATURE file to the distribution's
MANIFEST.

=item disttest

[version 0.05]

Performs the 'distdir' action, then switches into that directory and runs a
C<perl Build.PL>, followed by the 'build' and 'test' actions in that directory.
Use PERL_MB_OPT or F<.modulebuildrc> to set options that should be applied
during subprocesses


=item docs

[version 0.20]

This will generate documentation (e.g. Unix man pages and HTML
documents) for any installable items under B<blib/> that
contain POD.  If there are no C<bindoc> or C<libdoc> installation
targets defined (as will be the case on systems that don't support
Unix manpages) no action is taken for manpages.  If there are no
C<binhtml> or C<libhtml> installation targets defined no action is
taken for HTML documents.

=item fakeinstall

[version 0.02]

This is just like the C<install> action, but it won't actually do
anything, it will just report what it I<would> have done if you had
actually run the C<install> action.

=item help

[version 0.03]

This action will simply print out a message that is meant to help you
use the build process.  It will show you a list of available build
actions too.

With an optional argument specifying an action name (e.g. C<Build help
test>), the 'help' action will show you any POD documentation it can
find for that action.

=item html

[version 0.26]

This will generate HTML documentation for any binary or library files
under B<blib/> that contain POD.  The HTML documentation will only be
installed if the install paths can be determined from values in
C<Config.pm>.  You can also supply or override install paths on the
command line by specifying C<install_path> values for the C<binhtml>
and/or C<libhtml> installation targets.

With an optional C<html_links> argument set to a false value, you can
skip the search for other documentation to link to, because that can
waste a lot of time if there aren't any links to generate anyway:

  ./Build html --html_links 0

=item install

[version 0.01]

This action will use C<ExtUtils::Install> to install the files from
C<blib/> into the system.  See L<"INSTALL PATHS">
for details about how Module::Build determines where to install
things, and how to influence this process.

If you want the installation process to look around in C<@INC> for
other versions of the stuff you're installing and try to delete it,
you can use the C<uninst> parameter, which tells C<ExtUtils::Install> to
do so:

  ./Build install uninst=1

This can be a good idea, as it helps prevent multiple versions of a
module from being present on your system, which can be a confusing
situation indeed.

=item MODULEBUILDRC

[version 0.28]

Specifies an alternate location for a default options file as described above.

=item PERL_MB_OPT

[version 0.36]

Command line options that are applied to Build.PL or any Build action.  The
string is split as the shell would (e.g. whitespace) and the result is
prepended to any actual command-line arguments.

=back

=head1 INSTALL PATHS

[version 0.19]

When you invoke Module::Build's C<build> action, it needs to figure
out where to install things.  The nutshell version of how this works
is that default installation locations are determined from
F<Config.pm>, and they may be overridden by using the C<install_path>
parameter.  An C<install_base> parameter lets you specify an
alternative installation root like F</home/foo>, and a C<destdir> lets
you specify a temporary installation directory like F</tmp/install> in
case you want to create bundled-up installable packages.

Natively, Module::Build provides default installation locations for
the following types of installable items:

=over 4

=item lib

Usually pure-Perl module files ending in F<.pm>.

=item arch

"Architecture-dependent" module files, usually produced by compiling
XS, L<Inline>, or similar code.

=item script

Programs written in pure Perl.  In order to improve reuse, try to make
these as small as possible - put the code into modules whenever
possible.

=item bin

"Architecture-dependent" executable programs, i.e. compiled C code or
something.  Pretty rare to see this in a perl distribution, but it
happens.

=item bindoc

Documentation for the stuff in C<script> and C<bin>.  Usually
generated from the POD in those files.  Under Unix, these are manual
pages belonging to the 'man1' category.

=item libdoc

Documentation for the stuff in C<lib> and C<arch>.  This is usually
generated from the POD in F<.pm> files.  Under Unix, these are manual
pages belonging to the 'man3' category.

=item binhtml

This is the same as C<bindoc> above, but applies to HTML documents.

=item libhtml

This is the same as C<libdoc> above, but applies to HTML documents.

=back

Four other parameters let you control various aspects of how
installation paths are determined:

=over 4

=item installdirs

The default destinations for these installable things come from
entries in your system's C<Config.pm>.  You can select from three
different sets of default locations by setting the C<installdirs>
parameter as follows:

                          'installdirs' set to:
                   core          site                vendor

              uses the following defaults from Config.pm:

  lib     => installprivlib  installsitelib      installvendorlib
  arch    => installarchlib  installsitearch     installvendorarch
  script  => installscript   installsitescript   installvendorscript
  bin     => installbin      installsitebin      installvendorbin
  bindoc  => installman1dir  installsiteman1dir  installvendorman1dir
  libdoc  => installman3dir  installsiteman3dir  installvendorman3dir
  binhtml => installhtml1dir installsitehtml1dir installvendorhtml1dir [*]
  libhtml => installhtml3dir installsitehtml3dir installvendorhtml3dir [*]

  * Under some OS (eg. MSWin32) the destination for HTML documents is
    determined by the C<Config.pm> entry C<installhtmldir>.

The default value of C<installdirs> is "site".  If you're creating
vendor distributions of module packages, you may want to do something
like this:

  perl Build.PL --installdirs vendor

or

  ./Build install --installdirs vendor

If you're installing an updated version of a module that was included
with perl itself (i.e. a "core module"), then you may set
C<installdirs> to "core" to overwrite the module in its present
location.

(Note that the 'script' line is different from C<MakeMaker> -
unfortunately there's no such thing as "installsitescript" or
"installvendorscript" entry in C<Config.pm>, so we use the
"installsitebin" and "installvendorbin" entries to at least get the
