NAME

       ExtUtils::ModuleMaker - Better than h2xs for creating modules

SYNOPSIS

       At the command prompt:

           %   modulemaker

       Inside a Perl program:

           use ExtUtils::ModuleMaker;

           $mod = ExtUtils::ModuleMaker->new(
               NAME => 'Sample::Module'
           );

           $mod->complete_build();

           $mod->dump_keys(qw|
               ...  # key provided as argument to constructor
               ...  # same
           |);

           $mod->dump_keys_except(qw|
               ...  # key provided as argument to constructor
               ...  # same
           |);

           $license = $mod->get_license();

           $mod->make_selections_defaults();

VERSION

       This document references version 0.52 of ExtUtils::ModuleMaker, released to CPAN on July 04 2014.

DESCRIPTION

       This module is a replacement for the most typical use of the h2xs utility bundled with all Perl
       distributions:  the creation of the directories and files required for a pure-Perl module to be
       installable with make and distributable on the Comprehensive Perl Archive Network (CPAN).

       h2xs has many options which are useful -- indeed, necessary -- for the creation of a properly structured
       distribution that includes C code as well as Perl code.  Most of the time, however, h2xs is used as
       follows

           %   h2xs -AXn My::Module

       to create a distribution containing only Perl code.  ExtUtils::ModuleMaker is intended to be an easy-to-
       use replacement for this use of h2xs.

       While you can call ExtUtils::ModuleMaker from within a Perl script (as in the SYNOPSIS above), it's
       easier to use with a command-prompt invocation of the modulemaker script bundled with this distribution:

           %   modulemaker

       Then respond to the prompts.  For Perl programmers, laziness is a virtue -- and modulemaker is far and
       away the laziest way to create a pure Perl distribution which meets all the requirements for worldwide
       distribution via CPAN.

USAGE

   Usage from the command-line with modulemaker
       The easiest way to use ExtUtils::ModuleMaker is to invoke the modulemaker script from the command-line.
       You can control the content of the files built by modulemaker either by supplying command-line options or
       -- easier still -- replying to the screen prompts in modulemaker's interactive mode.

       If you are encountering ExtUtils::ModuleMaker for the first time, you should turn now to the
       documentation for modulemaker which is bundled this distribution.  Return to this document once you have
       become familiar with modulemaker.

   Use of Public Methods within a Perl Program
       You can use ExtUtils::ModuleMaker within a Perl script to generate the directories and files needed to
       begin work on a CPAN-ready Perl distribution.  You will need to call "new()" and "complete_build()", both
       of which are described in the next section.  These two methods control the building of the file and
       directory structure for a new Perl distribution.

       There are four other publicly available methods in this version of ExtUtils::ModuleMaker.  "dump_keys",
       "dump_keys_except" and "get_license" are intended primarily as shortcuts for trouble-shooting problems
       with an ExtUtils::ModuleMaker object.  "make_selections_defaults" enables you to be even lazier in your
       use of ExtUtils::ModuleMaker by saving keystrokes entered for attributes.

       "new"

       Creates and returns an ExtUtils::ModuleMaker object.  Takes a list containing key-value pairs with
       information specifying the structure and content of the new module(s).  (In this documentation, we will
       sometimes refer to these key-value pairs as the attributes of the ExtUtils::ModuleMaker object.)  With
       the exception of key "EXTRA_MODULES" (see below), the values in these pairs are all strings.  Like most
       such lists of key-value pairs, this list is probably best held in a hash.   Keys which may be specified
       are:

       •   Required Argument

           •   NAME

               The only required feature.  This is the name of the primary module (with '"::"' separators if
               needed).  Will no longer support the older, Perl 4-style separator ''"'"'' like the module D'Oh.
               There is no current default for NAME; you must supply a name explicitly.

       •   Other Important Arguments

           •   ABSTRACT

               A short description of the module.  CPAN likes to use this feature to describe the module.  If
               the abstract contains an apostrophe ("'"), then the value corresponding to key "ABSTRACT" in the
               list passed to the constructor must be double-quoted; otherwise Makefile.PL gets messed up.
               Certain CPAN indexing features still work better if the abstract is 44 or fewer characters in
               length, but this does not appear to be as mandatory as in the past.  (Defaults to dummy copy.)

           •   VERSION

               A string holding the version number.  For alpha releases, include an underscore to the right of
               the dot like "0.31_21". (Default is 0.01.)

           •   LICENSE

               Which license to include in the Copyright section.  You can choose one of the standard licenses
               by including 'perl', 'gpl', 'artistic', and 18 others approved by opensource.org.  The default is
               to choose the 'perl' flavor which is to share it ''under the same terms as Perl itself.''

               Other licenses can be added by individual module authors to
               ExtUtils::ModuleMaker::Licenses::Local to keep your company lawyers happy.

               Some licenses include placeholders that will be replaced with AUTHOR information.

           •   BUILD_SYSTEM

               This can take one of three values:

               •   'ExtUtils::MakeMaker'

                   The first generates a basic Makefile.PL file for your module.

               •   'Module::Build'

                   The second creates a Build.PL file.

               •   'Module::Build and Proxy'

                   The third creates a Build.PL along with a proxy Makefile.PL script that attempts to install
                   Module::Build if necessary, and then runs the Build.PL script.  This option is recommended if
                   you want to use Module::Build as your build system.  See Module::Build::Compat for more
                   details.

                   Note:  To correct a discrepancy between the documentation and code in earlier versions of
                   ExtUtils::ModuleMaker, we now explicitly provide this synonym for the third option:

                       'Module::Build and proxy Makefile.PL'

                   (Thanks to David A Golden for spotting this bug.)

           •   COMPACT

               For a module named ''Foo::Bar::Baz'' creates a base directory named ''Foo-Bar-Baz'' instead of
               Foo/Bar/Baz.  (Default is off.)

           •   VERBOSE

               Prints messages to STDOUT as it creates directories, writes files, etc. (Default is off.)

           •   PERMISSIONS

               Used to create new directories.  (Default is 0755:  group and world can not write.)

           •   USAGE_MESSAGE

               Message given when the module "die"s.  Scripts should set this to the same string it would print
               if the user asked for help.  (A reasonable default is provided.)

           •   NEED_POD

               Include POD section in *.pm files created.  (Default is on.)

           •   NEED_NEW_METHOD

               Include a simple "new()" method in the *.pm files created.  (Default is on.)

           •   CHANGES_IN_POD

               Omit a Changes file, but instead add a HISTORY section to the POD.  (Default is off).

           •   INCLUDE_MANIFEST_SKIP

               Boolean value which, if true, includes a MANIFEST.SKIP file in the distribution with reasonable
               default values facilitating use of the make manifest command during module development.  (Thanks
               to David A Golden for this feature.  Default is off.)

           •   INCLUDE_TODO

               Boolean value which, if true, includes a Todo file in the distribution in which the module's
               author or maintainer can discuss future lines of development.  (Default is on.)

           •   INCLUDE_LICENSE

               Boolean value which, if true, includes a LICENSE file in the distribution.  (Which LICENSE file
               is determined in the LICENSE option.)  (Default is on.)

           •   INCLUDE_SCRIPTS_DIRECTORY

               Boolean value which, if true, includes a scripts/ directory (at the same level as lib/ or t/).
               (Default is on.)

           •   INCLUDE_WARNINGS

               Boolean value which, if true, inserts "use warnings;" in all Perl modules created by use of this
               module.  (Default is off.)

           •   INCLUDE_ID_LINE

               Boolean value which, if true, inserts "#$Id$" in all Perl modules created by use of this module
               for the purpose of inserting a Subversion file 'Id' string.  (Default is off.)

       •   Arguments Related to the Module's Author

           •   AUTHOR

               Name of the author.  If the author's name contains an apostrophe ("'"), then the corresponding
               value in the list passed to the constructor must be double-quoted; otherwise Makefile.PL gets
               messed up.  (Defaults to dummy copy.)

           •   EMAIL

               Email address of the author.  If the author's e-mail address contains an apostrophe ("'"), then
               the corresponding value in the list passed to the constructor must be double-quoted; otherwise
               Makefile.PL gets messed up.  (Defaults to dummy copy.)

           •   CPANID

               The CPANID of the author.  If this is omitted, then the line will not be added to the
               documentation.  (Defaults to dummy copy.)

           •   WEBSITE

               The personal or organizational website of the author.  If this is omitted, then the line will not
               be added to the documentation.  (Defaults to dummy copy.)

           •   ORGANIZATION

               Company or group owning the module.  If this is omitted, then the line will not be added to the
               documentation.  (Defaults to dummy copy.)

       •   Argument Related to Multiple Modules within a Distribution

           •   EXTRA_MODULES

               A reference to an array of hashes, each of which contains values for additional modules in the
               distribution.

                   $mod = ExtUtils::ModuleMaker->new(
                       NAME           => 'Alpha::Beta',
                       EXTRA_MODULES  => [
                           { NAME => 'Alpha::Beta::Gamma' },
                           { NAME => 'Alpha::Beta::Delta' },
                           { NAME => 'Alpha::Beta::Gamma::Epsilon' },
                       ],
                   );

               As with the primary module, the only attribute required for each extra module is "NAME".  Other
               attributes may be supplied but the primary module's values will be used if no value is given
               here.

               Each extra module will be created in the correct relative place in the lib directory.  By
               default, a test file will also be created in the t directory corresponding to each extra module
               to test that it loads properly.  (See EXTRA_MODULES_SINGLE_TEST_FILE below to learn how to change
               this behavior.)  However, no other supporting documents (e.g., README, Changes) will be created.

               This is one major improvement over the earlier h2xs as you can now build multi-module packages.

       •   Arguments Related to Test Files

           •   FIRST_TEST_NUMBER

               A non-negative natural number from which the count begins in test files that are numerically
               ordered.  (Default is 1.)

           •   TEST_NUMBER_FORMAT

               In test files that are numerically ordered, a Perl "sprintf" formatting string that specifies how
               FIRST_TEST_NUMBER is to be formatted.  (Default is "%03d".)

           •   TEST_NAME

               String forming the core of the name of a test file.  (Default is "load").

           •   TEST_NAME_DERIVED_FROM_MODULE_NAME

               Boolean value which, when true, tells ExtUtils::ModuleMaker to create a file in the test suite
               with a name derived from the .pm package it is testing, thereby overriding any value set in the
               TEST_NAME attribute.  For example, for a module called 'Alpha::Sigma::Tau', a test file named
               t/Alpha_Sigma_Tau.t will be created.  (Default is off.)

           •   TEST_NAME_SEPARATOR

               String holding the character which joins components of a test file's name, e.g., the character
               used to join 001 and <load> in a file named 001_load.t.  (Defaults to an underscore "_".)

           •   EXTRA_MODULES_SINGLE_TEST_FILE

               Boolean value which, when true and when extra modules have been specified in the EXTRA_MODULES
               attribute, will put tests for those extra modules in a single test file rather than in individual
               test files corresponding to each module.  (Default is off.)

           •   INCLUDE_POD_COVERAGE_TEST

               Boolean value which, if true, causes a test file called t/pod-coverage.t to be included in the t/
               directory.  This test is advocated by some Perl quality assurance experts and module authors.
               However, since the maintainer of ExtUtils::ModuleMaker is not persuaded of its worth, default is
               off.

           •   INCLUDE_POD_TEST

               Boolean value which, if true, causes a test file called t/pod.t to be included in the t/
               directory.  This test is advocated by some Perl quality assurance experts and module authors.
               However, since the maintainer of ExtUtils::ModuleMaker is not persuaded of its worth, default is
               off.

           •   INCLUDE_FILE_IN_PM

               String holding a path to a file containing Perl code and/or documentation which will be included
               in each lib/*.pm file created in a particular distribution. By default, such content is placed
               after any constructor and before the main POD block.  This could, for example, be used to insert
               stub subroutines in each package within a distribution.  Default is off.

       •   Arguments for Advanced Usages

           •   INTERACTIVE

               Activates interactive mode in modulemaker utility.  The interactive mode presents the user with a
               series of menus from which the user selects features by entering text at the command prompt.
               This attribute should only be used by interactive scripts like modulemaker.  (Default is off.)

           •   ALT_BUILD

               Name of a Perl package holding methods which override those called withiin "complete_build" to
               shape the content of files created by using ExtUtils::ModuleMaker.  See "An Alternative Approach
               to Subclassing" below.

       "complete_build"

       Creates all directories and files as configured by the key-value pairs passed to
       "ExtUtils::ModuleMaker::new".  Returns a true value if all specified files are created -- but this says
       nothing about whether those files have been created with the correct content.

       "dump_keys"

       When troubleshooting problems with an ExtUtils::ModuleMaker object, it is often useful to use
       Data::Dumper to dump the contents of the object.  Use "dump_keys()" when you only need to examine a few
       of the object's attributes.

           $mod->dump_keys( qw| NAME ABSTRACT | );

       "dump_keys_except"

       When troubleshooting problems with an ExtUtils::ModuleMaker object, it is often useful to use
       Data::Dumper to dump the contents of the object.  However, since certain elements of that object are
       often quite lengthy (e.g, the values of keys "LicenseParts" and "USAGE_MESSAGE"), it's handy to have a
       dumper function that dumps all keys except certain designated keys.

           $mod->dump_keys_except(qw| LicenseParts USAGE_MESSAGE |);

       "get_license"

       Returns a string which nicely formats a short version of the License and Copyright information.

           $license = $mod->get_license();
           print $license;

       ... will print something like this:

           =====================================================================
           =====================================================================
           [License Information]
           =====================================================================
           =====================================================================
           [Copyright Information]
           =====================================================================
           =====================================================================

       (Earlier versions of ExtUtils::ModuleMaker contained a "Display_License" function in each of submodules
       ExtUtils::ModuleMaker::Licenses::Standard and ExtUtils::ModuleMaker::Licenses::Local.  These functions
       were never publicly documented or tested.  "get_license()" is intended as a replacement for those two
       functions.)

       "make_selections_defaults()"

       Saves the values you entered as arguments passed to "new()" in a personal defaults file so that they
       supersede the defaults provided by ExtUtils::ModuleMaker itself.

       This is an advanced usage of ExtUtils::ModuleMaker.  If you have used ExtUtils::ModuleMaker more than
       once, you have probably typed in a choice for "AUTHOR", "EMAIL", etc., more than once.  To save
       unnecessary typing and reduce typing errors, ExtUtils::ModuleMaker now offers you the possibility of
       establishing personal default values which override the default values supplied with the distribution and
       found in lib/ExtUtils/ModuleMaker/Defaults.pm.

       Suppose that you have called "ExtUtils::ModuleMaker::new()" as follows:

           $mod = ExtUtils::ModuleMaker->new(
               NAME            => 'Sample::Module',
               ABSTRACT        => 'Now is the time to join the party',
               AUTHOR          => 'Hilton Stallone',
               CPANID          => 'RAMBO',
               ORGANIZATION    => 'Parliamentary Pictures',
               WEBSITE         => 'http://parliamentarypictures.com',
               EMAIL           => 'hiltons@parliamentarypictures.com',
           );

       While $mod is still in scope, you can call:

           $mod->make_selections_defaults()

       and the values selected  -- with two important exceptions -- will be saved in a Personal/Defaults.pm file
       stored in your home directory.  The next time you invoke ExtUtils::ModuleMaker, the new values will
       appear in the appropriate locations in the files created by "complete_build()".  They will also appear in
       the menus provided on screen by the modulemaker utility.

       What are those two important exceptions?

       •   "NAME"

           You cannot enter a default value for "NAME":  the name of the module you are creating.
           ExtUtil::ModuleMaker's own defaults file omits a value for "NAME" to prevent you from overwriting an
           already existing module.  (More precisely, the default value is an empty string.
           ExtUtil::ModuleMaker will throw an error if you attempt to create a module whose name is empty.)
           This precaution applies to your personal defaults file as well.

       •   "ABSTRACT"

           Since every module you create presumably has its own unique purpose, every module must have a unique
           "ABSTRACT" to summarize that purpose.  ExtUtil::ModuleMaker supplies the following string as the
           default value for the "ABSTRACT" key:

               Module abstract (<= 44 characters) goes here

           ... a string which, not coincidentally, happens to be exactly 44 characters long -- so you can just
           overstrike it.  This will be the default value for "ABSTRACT" in any Personal/Defaults.pm file you
           create as well.

CUSTOMIZATION

       ExtUtils::ModuleMaker is designed to be customizable to your needs and to offer you more flexibility as
       you become more experienced with it.

   Via modulemaker Utility Interactive Mode
       As with everything else about ExtUtils::ModuleMaker, the easiest, laziest way to get started is via the
       modulemaker utility; see its documentation.  Suppose that you have entered your correct name, email
       address and website at the prompts in modulemaker's Author Menu.

         N - Name of module              ''

         G - Generate module
         H - Generate module;
             save selections as defaults

         X - Exit immediately

         Please choose which feature you would like to edit:

       Select "H" instead of "G" to generate the distribution.  An internal call to "make_selections_defaults()"
       will save those selections in a personal defaults file and present them to you on the Author Menu the
       next time you go to use it.

   Via modulemaker Utility Command-Line Options Mode
       For simplicity, not all of ExtUtils::ModuleMaker's default values are represented on modulemaker's menus.
       Those that are not represented on those menus cannot be changed from there.  They can, however, in many
       cases be specified as options passed to modulemaker on the command-line and automatically saved as
       personal defaults by including the "s" flag as one of those options.  If, for example, your name is 'John
       Q Public' and you want all modules you create to have compact top-level directories, you would call:

           %   modulemaker -Icsn Sample::Module -u 'John Q Public'

       A distribution with a top-level directory Sample-Module would be created.  'John Q Public' would appear
       in appropriate places in Sample-Module/Makefile.PL and Sample-Module/lib/Sample/Module.pm.  You could
       then throw away the entire Sample-Module directory tree.  The next time you call "modulemaker", the call

           %   modulemaker -In Second::Module

       would suffice to generate a compact top-level directory and 'John Q Public' would appear in appropriate
       locations instead of the dreaded 'A. U. Thor'.

   Via "ExtUtils::ModuleMaker::new()"
       In all cases, ExtUtils::ModuleMaker's default values can be overridden with arguments passed to "new()"
       inside a Perl program.  The overriding can then be made permanent by calling
       "make_selections_defaults()".

       Suppose, for example,

       1.  that you want the files in your test suite to appear in a numerical order starting from 0 rather than
           ExtUtils::ModuleMaker's own default starting point of 1;

       2.  that you want the number in the test file's name to be formatted as a two-digit string padded with
           zeroes rather than ExtUtils::ModuleMaker's own default format of a three-digit, zero-padded string;

       3.  that you want the numerical part of the test filename to be joined to the lexical part with a dot
           (".") rather than ExtUtils::ModuleMaker's own default linkage character of an underscore ("_"); and

       4.  that you want the lexical part of the test filename to reflect the module's name rather than
           ExtUtils::ModuleMaker's default of "load".

       Your Perl program would look like this:

           #!/usr/local/bin/perl
           use strict;
           use warnings;
           use ExtUtils::ModuleMaker;

           my $mod = ExtUtils::ModuleMaker->new(
               NAME        => 'Sample::Module',
               AUTHOR      => 'John Q Public',
               COMPACT     => 1,
               FIRST_TEST_NUMBER    => 0,
               TEST_NUMBER_FORMAT   => "%02d",
               TEST_NAME_SEPARATOR  => q{.},
               TEST_NAME_DERIVED_FROM_MODULE_NAME => 1,
           );

           $mod->make_selections_defaults();

       A subsequent call to the modulemaker utility,

           %    modulemaker -In Second::Balcony::Jump

       would generate a directory tree with a compact top-level, 'John Q Public' in appropriate locations in
       Second-Balcony-Jump/Makefile.PL and Second-Balcony-Jump/lib/Second/Balcony/Jump.pm and a test file called
       Second-Balcony-Jump/t/00.Second.Balcony.Jump.t.

   Via Subclassing ExtUtils::ModuleMaker
       If you're a power-user, once you start playing with ExtUtils::ModuleMaker, you won't be able to stop.
       You'll ask yourself, ''Self, if I can change the default values, why can't I change the 'boilerplate'
       copy that appears inside the files which ExtUtils::ModuleMaker creates?''

       Now, you can.  You can hack on the methods which "ExtUtils::ModuleMaker::new()" and "complete_build()"
       call internally to customize their results to your heart's desire.  The key:  build an entirely new Perl
       extension whose lib/*.pm file has methods that override the methods you need overridden -- and only those
       methods.  Follow these steps:

       1. Study ExtUtils::ModuleMaker::Defaults, ::Initializers and ::StandardText

       ExtUtils::ModuleMaker's default values are stored in lib/ExtUtils/ModuleMaker/Defaults.pm, specifically,
       in its "default_values()" method.  Identify those values which you wish to change.

       ExtUtils::ModuleMaker's other internal methods are found in two other files:
       /lib/ExtUtils/ModuleMaker/Initializers.pm and lib/ExtUtils/ModuleMaker/StandardText.pm.  Rule of thumb:
       If an internal method is called within "new()", it is found in ExtUtils::ModuleMaker::Initializers.  If
       it is called within "complete_build()", it is found in ExtUtils::ModuleMaker::StandardText.  Study these
       two packages to identify the methods you wish to override.

       Hint:  If changing a default value in ExtUtils::ModuleMaker::Defaults will achieve your objective, make
       that change rather than trying to override methods in ExtUtils::ModuleMaker::Initializers or
       ExtUtils::ModuleMaker::StandardText.

       Hint:  You should probably think about overriding methods in ExtUtils::ModuleMaker::StandardText before
       overriding those in ExtUtils::ModuleMaker::Initializers.

       2. Use modulemaker to Create the Framework for a New Distribution

       You're creating a new Perl extension.  Who ya gonna call?  modulemaker, natch!  (If you have not read the
       documentation for modulemaker by this point, do so now.)

       Suppose that you've gotten on the 'Perl Best Practices' bandwagon and want to create all your Perl
       extensions in the style recommended by Damian Conway in the book of the same name.  Use modulemaker to
       create the framework:

           %    modulemaker -Icqn ExtUtils::ModuleMaker::PBP \
                -u 'James E Keenan' \
                -p JKEENAN \
                -o 'Perl Seminar NY' \
                -w http://search.cpan.org/~jkeenan/

       You used the "-q" option above because you do not want or need a constructor in the new package you are
       creating.  That package will inherit its constructor from ExtUtils::ModuleMaker.

       3. Edit the lib/*.pm File

       Open up the best text-editor at your disposal and proceed to hack:

           %    vi ExtUtils-ModuleMaker-PBP/lib/ExtUtils/ModuleMaker/PBP.pm

       Add this line near the top of the file:

           use base qw{ ExtUtils::ModuleMaker };

       so that ExtUtils::ModuleMaker::PBP inherits from ExtUtils::ModuleMaker (which, in turn, inherits from
       ExtUtils::ModuleMaker::Defaults, ExtUtils::ModuleMaker::Initializers and
       ExtUtils::ModuleMaker::StandardText).

       If you have carefully studied ExtUtils::ModuleMaker::Defaults, ExtUtils::ModuleMaker::StandardText and
       Perl Best Practices, you will write methods including the following:

           sub default_values {
               my $self = shift;
               my $defaults_ref = $self->SUPER::default_values();
               $defaults_ref->{COMPACT}                        = 1;
               $defaults_ref->{FIRST_TEST_NUMBER}              = 0;
               $defaults_ref->{TEST_NUMBER_FORMAT}             = "%02d";
               $defaults_ref->{EXTRA_MODULES_SINGLE_TEST_FILE} = 1;
               $defaults_ref->{TEST_NAME_SEPARATOR}            = q{.};
               $defaults_ref->{INCLUDE_TODO}                   = 0;
               $defaults_ref->{INCLUDE_POD_COVERAGE_TEST}      = 1;
               $defaults_ref->{INCLUDE_POD_TEST}               = 1;
               return $defaults_ref;;
           }

           sub text_Makefile {
               my $self = shift;
               my $Makefile_format = q~
           use strict;
           use warnings;
           use ExtUtils::MakeMaker;

           WriteMakefile(
               NAME            => '%s',
               AUTHOR          => '%s <%s>',
               VERSION_FROM    => '%s',
               ABSTRACT_FROM   => '%s',
               PL_FILES        => {},
               PREREQ_PM    => {
                   'Test::More'    => 0,
                   'version'       => 0,
               },
               dist            => { COMPRESS => 'gzip -9f', SUFFIX => 'gz', },
               clean           => { FILES => '%s-*' },
           );
           ~;
               my $text_of_Makefile = sprintf $Makefile_format,
                   map { my $s = $_; $s =~ s{'}{\\'}g; $s; }
                       $self->{NAME},
                       $self->{AUTHOR},
                       $self->{EMAIL},
                       $self->{FILE},
                       $self->{FILE},
                       $self->{FILE};
               return $text_of_Makefile;
           }

       Of course, for true Perl laziness, you'll use CPAN distribution ExtUtils::ModuleMaker::PBP, written by
       the author of ExtUtils::ModuleMaker as an exemplar of subclassing ExtUtils::ModuleMaker and generating
       the same output as Damian Conway's Module::Starter::PBP.

       4. Test

       How do you know you have correctly subclassed ExtUtils::ModuleMaker?  With a test suite, of course.  With
       careful editing, you can use many of ExtUtils::ModuleMaker's own tests in your new distribution.  You
       will, of course, have to change a number of tests, because the default values implied by Conway's
       recommendations are different from ExtUtils::ModuleMaker's own defaults.  Among other things, you will
       have to do a search-and-replace on all constructor calls.

           %    perl -pi'*.bak' -e 's{ExtUtils::ModuleMaker->new}{ExtUtils::ModuleMaker::PBP->new}g;'

       Of course, you should have written your tests first, right?

       5. Install and Use

       You would install your new distribution as you would any other Perl distribution, i.e., with either
       ExtUtils::MakeMaker or Module::Build, depending on which you chose in creating your subclass.

           #!/usr/local/bin/perl
           use strict;
           use warnings;
           use ExtUtils::ModuleMaker::PBP;

           my $mod = ExtUtils::ModuleMaker::PBP->new(
               NAME        => 'Sample::Module',
           );

           $mod->complete_build();

       For an adaptation of the modulemaker utility to work with ExtUtils::ModuleMaker::PBP, see mmkrpbp which
       is bundled with the latter package.

       An Alternative Approach to Subclassing

       There is one other way to subclass to ExtUtils::ModuleMaker which bears mentioning, more because the
       author used it in the development of this version of ExtUtils::ModuleMaker than because it is
       recommended.  If for some reason you do not wish to create a full-fledged Perl distribution for your
       subclass, you can simply write the subclassing package and store it in the same directory hierarchy on
       your system in which your personal defaults file is stored.

       For example, suppose you are experimenting and only wish to override one method in
       ExtUtils::ModuleMaker::StandardText.  You can create a package called
       ExtUtils::ModuleMaker::AlternativeText.  If you are working on a Unix-like system, you would move that
       file such that its path would be:

           "$ENV{HOME}/.modulemaker/ExtUtils/ModuleMaker/AlternativeText.pm"

       You would then add one argument to your call to "ExtUtils::ModuleMaker::new()":

           my $mod = ExtUtils::ModuleMaker->new(
               NAME        => 'Sample::Module',
               ALT_BUILD   => 'ExtUtils::ModuleMaker::AlternativeText',
           );

CAVEATS

       •   Tests Require Perl 5.6

           While the maintainer has attempted to make the code in lib/ExtUtils/Modulemaker.pm and the
           modulemaker utility compatible with versions of Perl older than 5.6, the test suite currently
           requires 5.6 or later.  The tests which require 5.6 or later are placed in SKIP blocks.  Since the
           overwhelming majority of the tests do require 5.6, running the test suite on earlier Perl versions
           won't report much that is meaningful.

       •   Testing of modulemaker's Interactive Mode

           The easiest, laziest and recommended way of using this distribution is the command-line utility
           modulemaker, especially its interactive mode.  However, this is necessarily the most difficult test,
           as its testing would require capturing the STDIN, STDOUT and STDERR for a process spawned by a
           "system('modulemaker')" call from within a test file.  For now, the maintainer has relied on repeated
           visual inspection of the screen prompts generated by modulemaker.  With luck, Expect-based tests will
           be available in a future version.

       •   Testing modulemaker on Non-*nix-Like Operating Systems

           Since testing the modulemaker utility from within the test suite requires a "system()" call, a clean
           test run depends in part on the way a given operating system parses command-line arguments.  The
           maintainer has tested this on Darwin and Win32 and, thanks to a suggestion by A.  Sinan Unur, solved
           a problem on Win32.  Results on other operating systems may differ; feedback is welcome.

TO DO

       •   Tests for modulemaker's interactive mode.

       •   Possible new "USE_AS_BASE" attribute which would insert modules from which user's new module will
           inherit.

               USE_AS_BASE => [ qw|
                   Template::Toolkit
                   Module::Build
                   Lingua::Romana::Perligata
                   Acme::Buffy
               | ],

           Such an attribute would require replacement copy for
           "ExtUtils::ModuleMaker::StandardText::block_begin()".

       •   Creation of a mailing list for ExtUtils::ModuleMaker.

ACKNOWLEDGMENTS

       Thanks first and foremost to Geoff Avery for creating ExtUtils::Modulemaker and popularizing it via
       presentations I attended at YAPC::NA::2003 (Boca Raton) and YAPC::EU::2003 (Paris).

       Soon after I took over maintenance of ExtUtils::ModuleMaker, David A Golden became a driving force in its
       ongoing development, providing suggestions for additional functionality as well as bug reports.  David is
       the author of ExtUtils::ModuleMaker::TT which, while not a pure subclass of ExtUtils::ModuleMaker,
       extends its functionality for users of Template::Toolkit.

       Thanks for suggestions about testing the modulemaker utility to Michael G Schwern on perl.qa and A Sinan
       Unur and Paul Lalli on comp.lang.perl.misc.  Thanks for help in dealing with a nasty bug in the testing
       to Perlmonks davidrw and tlm.  That well known Perl hacker, Anonymous Guest, contributed another bug
       report  on rt.cpan.org.

       As development proceeded, several issues were clarified by members of Perlmonks.org.  CountZero, xdg,
       Tanktalus, holli, TheDamian and nothingmuch made particularly useful suggestions, as did Brian Clarkson.

       Thanks also go to the following beta testers:  Alex Gill, Marc Prewitt, Scott Godin, Reinhard Urban and
       imacat.

       Version 0.39 of ExtUtils::ModuleMaker encountered spurious testing failure reports from testers.cpan.org.
       These were eventually diagnosed as being due to bugs in the automated testing programs and/or their
       operating environments on different systems -- i.e., to problems outside ExtUtils::ModuleMaker itself.
       Several Perlmonks helped investigate this problem:  chromatic, dave_the_m, randyk, and njh.

       Thanks to Paul M Sirianni for reporting bugs that led to versions 0.48 and 0.51.
