.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fBModule::Install\fR is a package for writing installers for \s-1CPAN\s0 (or
CPAN-like) distributions that are clean, simple, minimalist, act in a
strictly correct manner with ExtUtils::MakeMaker, and will run on
any Perl installation version 5.005 or newer.
.PP
The intent is to make it as easy as possible for \s-1CPAN\s0 authors (and
especially for first-time \s-1CPAN\s0 authors) to have installers that follow
all the best practices for distribution installation, but involve as
much \s-1DWIM\s0 (Do What I Mean) as possible when writing them.
.SS "Writing Module::Install Installers"
.IX Subsection "Writing Module::Install Installers"
The quickest way to get started with Module::Install is to copy the
\&\*(L"\s-1SYNOPSIS\s0\*(R" from above and save it as your own \fIMakefile.PL\fR. Then
modify the file to suit your own particular case, using the list of
commands documented in \*(L"\s-1COMMON\s0 \s-1COMMANDS\s0\*(R" below.
.PP
If all you want to do is write an installer, go and do that now. You
don't really need the rest of this description unless you are
interested in the details.
.SH "How it Works"
.IX Header "How it Works"
The motivation behind \fBModule::Install\fR is that distributions need
to interact with a large number of different versions of perl and
module installers infrastructure, primarily \s-1CPAN\s0.pm, \s-1CPANPLUS\s0.pm,
ExtUtils::MakeMaker and Module::Build.
.PP
These have accumulated \fBgreatly\fR varying feature and bug profiles over
the years, and it is now very difficult to write an installer that will
work properly using only the installed versions of these modules,
.PP
For example, the \s-1CPAN\s0.pm version shipped with Perl 5.005 is now 5+
years old and considered highly buggy, yet it still exists on quite a
number of legacy machines.
.PP
Rather than try to target one specific installer and/or make you add
twisty workaround expressions to every piece of install code you write,
\&\fBModule::Install\fR will copy part of itself into each module distribution
it creates.
.PP
This allows new improvements to be used in your installers regardless of
the age of the system a distribution is being installed on, at the cost
of a small increase in the size of your distribution.
.SS "History"
.IX Subsection "History"
This module was originally written by Brian Ingerson as a smart drop-in
replacement for ExtUtils::MakeMaker.
.PP
For more information, see Brian's \fICreating Module Distributions with
Module::Install\fR in June 2003 issue of The Perl Journal
.PP
For a \fBlot\fR more information, and some personal opinions on the module
and its creation, see Module::Install::Philosophy.
.SH "COMMON COMMANDS"
.IX Header "COMMON COMMANDS"
The following are the most common commands generally used in installers.
.PP
It is far from an exhaustive list, as many of the plugins provide commands
to work in more details that you would normally need.
.SS "name"
.IX Subsection "name"
.Vb 1
\& name \*(AqMy\-Module\*(Aq;
.Ve
.PP
The \fBname\fR command is compulsory command, generally the first.
.PP
It provides the name of your distribution, which for a module like
\&\fBYour::Module\fR would normally be \f(CW\*(C`Your\-Module\*(C'\fR.
.PP
This naming scheme is not hard and fast and you should note that
distributions are actually a separate naming scheme from modules.
.PP
For example the \s-1LWP\s0 modules come in a distribution called
\&\f(CW\*(C`libwww\-perl\*(C'\fR.
.SS "all_from"
.IX Subsection "all_from"
.Vb 1
\& all_from \*(Aqlib/My/Module.pm\*(Aq;
.Ve
.PP
For most simple Perl distributions that feature one dominant module or
class as the base, you can get the most Do What I Mean functionality by
using the \fBall_from\fR command, which will try to extract as much
metadata as possible from the Perl code and \s-1POD\s0 in that primary module.
.PP
Functionally, \f(CW\*(C`all_from\*(C'\fR is equivalent to \f(CW\*(C`abstract_from\*(C'\fR +
\&\f(CW\*(C`author_from\*(C'\fR + \f(CW\*(C`version_from\*(C'\fR + \f(CW\*(C`license_from\*(C'\fR +
\&\f(CW\*(C`perl_version_from\*(C'\fR. See below for details.
.PP
If any of these values are set already \fBbefore\fR \f(CW\*(C`all_from\*(C'\fR is used,
they will kept and \fBnot\fR be overwritten.
.SS "abstract"
.IX Subsection "abstract"
.Vb 1
\& abstract \*(AqThis distribution does something\*(Aq;
.Ve
.PP
All distributions have an abstract, a short description of the
distribution as a whole. It is usually around 30\-70 characters long.
.PP
The \f(CW\*(C`abstract\*(C'\fR command is used to explicitly set the abstract for the
distribution, at least as far as the metadata file for the distribution
is concerned.
.SS "abstract_from"
.IX Subsection "abstract_from"
.Vb 1
\& abstract_from \*(Aqlib/My/Module.pm\*(Aq;
.Ve
.PP
The \f(CW\*(C`abstract_from\*(C'\fR command retrieves the abstract from a particular
file contained in the distribution package. Most often this is done
from the main module, where \f(CW\*(C`Module::Install\*(C'\fR will read the \s-1POD\s0 and
use whatever is in the \f(CW\*(C`=head1 NAME\*(C'\fR section (with module name stripped
if needed)
.PP
\&\f(CW\*(C`abstract_from\*(C'\fR is set as part of \f(CW\*(C`all_from\*(C'\fR.
.SS "author"
.IX Subsection "author"
.Vb 1
\& author \*(AqAdam Kennedy <adamk@cpan.org>\*(Aq;
.Ve
.PP
The distribution metadata contains information on the primary author
or the distribution, or the primary maintainer if the original author
is no longer involved. It should generally be specified in the form
of an email address.
.PP
It you don't want to give away a real email address, you should use
the \f(CW\*(C`CPANID@cpan.org\*(C'\fR address you receive automatically when you
got your \s-1PAUSE\s0 account.
.PP
The \f(CW\*(C`author\*(C'\fR command is used to explicitly set this value.
.SS "author_from"
.IX Subsection "author_from"
.Vb 1
\& author_from \*(Aqlib/My/Module.pm\*(Aq;
.Ve
.PP
The \f(CW\*(C`author_from\*(C'\fR command retrieves the author from a particular
file contained in the distribution package. Most often this is done
using the main module, where Module::Install will read the \s-1POD\s0
and use whatever it can find in the \f(CW\*(C`=head1 AUTHOR\*(C'\fR section.
.SS "version"
.IX Subsection "version"
.Vb 1
\& version \*(Aq0.01\*(Aq;
.Ve
.PP
The \f(CW\*(C`version\*(C'\fR command is used to specify the version of the
distribution, as distinct from the version of any single module within
the distribution.
.PP
Of course, in almost all cases you want it to match the version of the
primary module within the distribution, which you can do using
\&\f(CW\*(C`version_from\*(C'\fR.
.SS "version_from"
.IX Subsection "version_from"
.Vb 1
\& version_from \*(Aqlib/My/Module.pm\*(Aq;
.Ve
.PP
The \f(CW\*(C`version_from\*(C'\fR command retrieves the distribution version from a
particular file contained in the distribution package. Most often this is
done from the main module.
.PP
\&\f(CW\*(C`version_from\*(C'\fR will look for the first time you set \f(CW$VERSION\fR and use
the same value, using a technique consistent with various other module
version scanning tools.
.SS "license"
.IX Subsection "license"
.Vb 1
\& license \*(Aqperl\*(Aq;
.Ve
.PP
The \f(CW\*(C`license\*(C'\fR command specifies the license for the distribution.
.PP
Most often this value will be \f(CW\*(Aqperl\*(Aq\fR, meaning \fI\*(L"the same as for Perl
itself\*(R"\fR. Other allowed values include \f(CW\*(Aqgpl\*(Aq\fR, \f(CW\*(Aqlgpl\*(Aq\fR, \f(CW\*(Aqbsd\*(Aq\fR,
\&\f(CW\*(AqMIT\*(Aq\fR, and \f(CW\*(Aqartistic\*(Aq\fR.
.PP
This value is always considered a summary, and it is normal for authors
to include a \fI\s-1LICENSE\s0\fR file in the distribution, containing the full
license for the distribution.
.PP
You are also reminded that if the distribution is intended to be uploaded
to the \s-1CPAN\s0, it \fBmust\fR be an OSI-approved open source license. Commercial
software is not permitted on the \s-1CPAN\s0.
.SS "license_from"
.IX Subsection "license_from"
.Vb 1
\& license_from \*(Aqlib/My/Module.pm\*(Aq;
.Ve
.PP
The \f(CW\*(C`license_from\*(C'\fR command retrieves the distribution license from a
particular file contained in the distribution package. Most often this
is done from the main module.
.PP
\&\f(CW\*(C`license_from\*(C'\fR will look inside the \s-1POD\s0 within the indicated file for
a licensing or copyright-related section and scan for a variety of
strings that identify the general class of license.
.PP
At this time it supports only the 6 values mentioned above in the
\&\f(CW\*(C`license\*(C'\fR command summary.
.SS "perl_version"
.IX Subsection "perl_version"
.Vb 1
\& perl_version \*(Aq5.006\*(Aq;
.Ve
.PP
The \f(CW\*(C`perl_version\*(C'\fR command is used to specify the minimum version of the
perl interpreter your distribution requires.
.PP
When specifying the version, you should try to use the normalized version
string. Perl version segments are 3 digits long, so a dependency on Perl
5.6 will become \f(CW\*(Aq5.006\*(Aq\fR and Perl 5.10.2 will become \f(CW\*(Aq5.010002\*(Aq\fR.
.SS "perl_version_from"
.IX Subsection "perl_version_from"
.Vb 1
\& perl_version_from \*(Aqlib/My/Module.pm\*(Aq
.Ve
.PP
The \f(CW\*(C`perl_version_from\*(C'\fR command retrieves the minimum \fIperl\fR interpreter
version from a particular file contained in the distribution package. Most
often this is done from the main module.
.PP
The minimum version is detected by scanning the file for \f(CW\*(C`use 5.xxx\*(C'\fR
pragma calls in the module file.
.SS "recommends"
.IX Subsection "recommends"
.Vb 1
\& recommends \*(AqText::CSV_XS\*(Aq => \*(Aq0.50\*(Aq
.Ve
.PP
The \f(CW\*(C`recommends\*(C'\fR command indicates an optional run-time module that
provides extra functionality. Recommended dependencies are not
needed to build or test your distribution, but are considered \*(L"nice
to have\*(R".
.PP
As with \*(L"requires\*(R", the dependency is on a \fBmodule\fR and not
a distribution. A version of zero indicates that any version of
the module is recommended.
.SS "requires"
.IX Subsection "requires"
.Vb 2
\& requires \*(AqList::Util\*(Aq => 0;
\& requires \*(AqLWP\*(Aq => \*(Aq5.69\*(Aq;
.Ve
.PP
The \f(CW\*(C`requires\*(C'\fR command indicates a normal run-time dependency of your
distribution on another module. Most distributions will have one or
more of these commands, indicating which \s-1CPAN\s0 (or otherwise) modules
your distribution needs.
.PP
A \f(CW\*(C`requires\*(C'\fR dependency can be verbalised as \fI\*(L"If you wish to install
and use this distribution, you must first install these modules first\*(R"\fR.
.PP
Note that the dependency is on a \fBmodule\fR and not a distribution. This
is to ensure that your dependency stays correct, even if the module is
moved or merged into a different distribtion, as is occasionally the
case.
.PP
A dependency on version zero indicates \fBany\fR version of module is
sufficient. Versions should generally be quoted for clarity.
.SS "test_requires"
.IX Subsection "test_requires"
.Vb 1
\& test_requires \*(AqTest::More\*(Aq => \*(Aq0.47\*(Aq;
.Ve
.PP
The \f(CW\*(C`test_requires\*(C'\fR command indicates a test script dependency for
the distribution. The specification format is identical to that of
the \f(CW\*(C`requires\*(C'\fR command.
.PP
The \f(CW\*(C`test_requires\*(C'\fR command is distinct from the \f(CW\*(C`requires\*(C'\fR command
in that it indicates a module that is needed \fBonly\fR during the
testing of the distribution (often a period of only a few seconds)
but will \fBnot\fR be needed after the distribution is installed.
.PP
The \f(CW\*(C`testrequires\*(C'\fR command is used to allow the installer some
flexibility in how it provides the module, and to allow downstream
packagers (Debian, FreeBSD, ActivePerl etc) to retain only the
dependencies needed for run-time operation.
.PP
The \f(CW\*(C`include\*(C'\fR command is sometimes used by some authors along with
\&\f(CW\*(C`test_requires\*(C'\fR to bundle a small well-tested module into the
distribution package itself rather than inflict yet another module
installation on users installing from \s-1CPAN\s0 directly.
.SS "configure_requires"
.IX Subsection "configure_requires"
.Vb 1
\& configure_requires \*(AqFile::Spec\*(Aq => \*(Aq0.80\*(Aq;
.Ve
.PP
The \f(CW\*(C`configure_requires\*(C'\fR command indicates a configure-time dependency
for the distribution. The specification format is identical to that of
the \f(CW\*(C`requires\*(C'\fR command.
.PP
The \f(CW\*(C`configure_requires\*(C'\fR command is used to get around the conundrum
of how to use a \s-1CPAN\s0 module in your Makefile.PL, when you have to load
Makefile.PL (and thus the \s-1CPAN\s0 module) in order to know that you need it.
.PP
Traditionally, this circular logic could not be broken and so Makefile.PL
scripts needed to rely on lowest-common-denominator approaches, or to
bundle those dependencies using something like the \f(CW\*(C`include\*(C'\fR command.
.PP
The \f(CW\*(C`configure_requires\*(C'\fR command creates an entry in the special
configure_requires: key in the distribution's \fI\s-1META\s0.yml\fR file.
.PP
Although most of \fI\s-1META\s0.yml\fR is considered advisory only, a \s-1CPAN\s0
client will treat the contents of configure_requires: as authorative,
and install the listed modules \fBbefore\fR it executes the \fIMakefile.PL\fR
(from which it then determines the other dependencies).
.PP
Please note that support for configure_requires: in \s-1CPAN\s0 clients is not
100% complete at time of writing, and still cannot be relied upon.
.PP
Because \fBModule::Install\fR itself only supports 5.005, it will silently
add the equivalent of a \f(CW\*(C`configure_requires( perl => \*(Aq5.005\*(Aq );\*(C'\fR
command to your distribution.
.SS "requires_external_bin"
.IX Subsection "requires_external_bin"
.Vb 1
\& requires_external_bin \*(Aqcvs\*(Aq;
.Ve
.PP
As part of its role as the dominant \*(L"glue\*(R" language, a lot of Perl
modules run commands or programs on the host system.
.PP
The \f(CW\*(C`requires_external_bin\*(C'\fR command is used to verify that a particular
command is available on the host system.
.PP
Unlike a missing Perl module, a missing external binary is unresolvable
at make-time, and so the \fIMakefile.PL\fR run will abort with a \*(L"\s-1NA\s0\*(R"
(Not Applicable) result.
.PP
In future, this command will also add additional information to the
metadata for the dist, so that auto-packagers for particular operating
system are more-easily able to auto-discover the appropriate non-Perl
packages needed as a dependency.
.SS "install_script"
.IX Subsection "install_script"
.Vb 2
\& # The following are equivalent
\& install_script \*(Aqscript/scriptname\*(Aq
.Ve
.PP
The \f(CW\*(C`install_script\*(C'\fR command provides support for the installation of
scripts that will become available at the console on both Unix and
Windows (in the later case by wrapping it up as a .bat file).
.PP
Note that is it normal practice to \fBnot\fR put a .pl on the end of such
scripts, so that they feel more natural when being used.
.PP
In the example above, the \fIscript/scriptname\fR program could be run after
the installation just by doing the following.
.PP
.Vb 2
\& > scriptname
\& Running scriptname 0.01...
\&
\& >
.Ve
.PP
By convention, scripts should be placed in a /script directory within your
distribution. To support less typing, if a script is located in the script
directory, you need refer to it by name only.
.PP
.Vb 3
\& # The following are equivalent
\& install_script \*(Aqfoo\*(Aq;
\& install_script \*(Aqscript/foo\*(Aq;
.Ve
.SS "no_index"
.IX Subsection "no_index"
.Vb 2
\& no_index directory => \*(Aqexamples\*(Aq;
\& no_index package => \*(AqDB\*(Aq;
.Ve
.PP
Quite often a distrubition will provide example scripts or testing
modules (.pm files) as well as the actual library modules.
.PP
In almost all situations, you do \fBnot\fR want these indexed in the \s-1CPAN\s0
index, the master Perl packages list, or displayed on the
<http://search.cpan.org/> website, you just want them along for the
ride.
.PP
The \f(CW\*(C`no_index\*(C'\fR command is used to indicate directories or files where
there might be non-library .pm files or other files that the \s-1CPAN\s0
indexer and websites such as <http://search.cpan.org/> should
explicitly ignore.
.PP
The most common situation is to ignore example or demo directories,
but a variety of different situations may require a \f(CW\*(C`no_index\*(C'\fR entry.
.PP
Another common use for \f(CW\*(C`no_index\*(C'\fR is to prevent the \s-1PAUSE\s0 indexer
complaining when your module makes changes inside a \*(L"package \s-1DB\s0\*(R" block.
This is used to interact with the debugger in some specific ways.
.PP
See the \fI\s-1META\s0.yml\fR documentation for more details on what \f(CW\*(C`no_index\*(C'\fR
values are allowed.
.PP
The \fIinc\fR, \fIt\fR and \fIshare\fR (if \f(CW\*(C`install_share\*(C'\fR is used) directories
are automatically \f(CW\*(C`no_index\*(C'\fR'ed for you if found and do not require
an explicit command.
.PP
To summarize, if you can see it on <http://search.cpan.org/> and you
shouldn't be able to, you need a \f(CW\*(C`no_index\*(C'\fR entry to remove it.
.SS "installdirs, install_as_*"

.PP
The \f(CW\*(C`installdirs\*(C'\fR and \f(CW\*(C`install_as\*(C'\fR commands specify the location
where the module should be installed; this is the equivalent to
ExtUtils::MakeMaker's \f(CW\*(C`INSTALLDIRS\*(C'\fR option. For almost all
regular modules, the default is recommended, and need not be
changed. Dual-life (core and \s-1CPAN\s0) modules, as well as
vendor-specific modules, may need to use the other options.
.PP
If unsure, do not use this option.
.SS "WriteAll"
.IX Subsection "WriteAll"
The \f(CW\*(C`WriteAll\*(C'\fR command is generally the last command in the file;
it writes out \fI\s-1META\s0.yml\fR and \fIMakefile\fR so the user can run the
\&\f(CW\*(C`make\*(C'\fR, \f(CW\*(C`make test\*(C'\fR, \f(CW\*(C`make install\*(C'\fR install sequence.
.SH "EXTENSIONS"
.IX Header "EXTENSIONS"
All extensions belong to the \fBModule::Install::*\fR namespace, and
inherit from \fBModule::Install::Base\fR. There are three categories
of extensions:
.SS "Standard Extensions"
.IX Subsection "Standard Extensions"
Methods defined by a standard extension may be called as plain functions
inside \fIMakefile.PL\fR; a corresponding singleton object will be spawned
automatically. Other extensions may also invoke its methods just like
their own methods:
.PP
.Vb 2
\& # delegates to $other_extension_obj\->method_name(@args)
\& $self\->method_name(@args);
.Ve
.PP
At the first time an extension's method is invoked, a POD-stripped
version of it will be included under the \fIinc/Module/Install/\fR
directory, and becomes \fIfixed\fR \*(-- i.e., even if the user had installed a
different version of the same extension, the included one will still be
used instead.
.PP
If the author wish to upgrade extensions in \fIinc/\fR with installed ones,
simply run \f(CW\*(C`perl Makefile.PL\*(C'\fR again; \fBModule::Install\fR determines
whether you are an author by the existence of the \fIinc/.author/\fR
directory. End-users can reinitialize everything and become the author
by typing \f(CW\*(C`make realclean\*(C'\fR and \f(CW\*(C`perl Makefile.PL\*(C'\fR.
.SS "Private Extensions"
.IX Subsection "Private Extensions"
Those extensions take the form of \fBModule::Install::PRIVATE\fR and
\&\fBModule::Install::PRIVATE::*\fR.
.PP
Authors are encouraged to put all existing \fIMakefile.PL\fR magics into
such extensions (e.g. \fIModule::Install::PRIVATE\fR for common bits;
\&\fIModule::Install::PRIVATE::DISTNAME\fR for functions specific to a
distribution).
.PP
Private extensions should not to be released on \s-1CPAN\s0; simply put them
somewhere in your \f(CW@INC\fR, under the \f(CW\*(C`Module/Install/\*(C'\fR directory, and
start using their functions in \fIMakefile.PL\fR. Like standard
extensions, they will never be installed on the end-user's machine,
and therefore never conflict with other people's private extensions.
.SS "Administrative Extensions"
.IX Subsection "Administrative Extensions"
Extensions under the \fBModule::Install::Admin::*\fR namespace are never
included with the distribution. Their methods are not directly
accessible from \fIMakefile.PL\fR or other extensions; they are invoked
like this:
.PP
.Vb 2
\& # delegates to $other_admin_extension_obj\->method_name(@args)
\& $self\->admin\->method_name(@args);
.Ve
.PP
These methods only take effect during the \fIinitialization\fR run, when
\&\fIinc/\fR is being populated; they are ignored for end-users. Again,
to re-initialize everything, just run \f(CW\*(C`perl Makefile.PL\*(C'\fR as the author.
.PP
Scripts (usually one-liners in \fIMakefile\fR) that wish to dispatch
\&\fB\s-1AUTOLOAD\s0\fR functions into administrative extensions (instead of
standard extensions) should use the \fBModule::Install::Admin\fR module
directly. See Module::Install::Admin for details.
.SH "EXTENSIONS"
.IX Header "EXTENSIONS"
Detailed information is provided for all (some) of the relevant
modules via their own \s-1POD\s0 documentation.
.SS "Module::Install::AutoInstall"
.IX Subsection "Module::Install::AutoInstall"
Provides \f(CW\*(C`auto_install()\*(C'\fR to automatically fetch and install
prerequisites.
.SS "Module::Install::Base"
.IX Subsection "Module::Install::Base"
The base class for all extensions
.SS "Module::Install::Bundle"
.IX Subsection "Module::Install::Bundle"
Provides the \f(CW\*(C`bundle\*(C'\fR family of commands, allowing you to bundle
another \s-1CPAN\s0 distribution within your distribution.
.SS "Module::Install::Fetch"
.IX Subsection "Module::Install::Fetch"
Handles install-time fetching of files from remote servers via
\&\s-1FTP\s0 and \s-1HTTP\s0.
.SS "Module::Install::Include"
.IX Subsection "Module::Install::Include"
Provides the \f(CW\*(C`include\*(C'\fR family of commands for embedding modules
that are only need at build-time in your distribution and won't
be installed.
.SS "Module::Install::Inline"
.IX Subsection "Module::Install::Inline"
Provides \f(CW\*(C`&Inline\->write\*(C'\fR to replace \fBInline::MakeMaker\fR's
functionality for making \fBInline\fR\-based modules (and cleaning up).
.PP
However, you should invoke this with \f(CW\*(C`WriteAll( inline => 1 )\*(C'\fR.
.SS "Module::Install::Makefile"
.IX Subsection "Module::Install::Makefile"
Provides \f(CW\*(C`&Makefile\->write\*(C'\fR to generate a \fIMakefile\fR for you
distribution.
.SS "Module::Install::Metadata"
.IX Subsection "Module::Install::Metadata"
Provides \f(CW\*(C`&Meta\->write\*(C'\fR to generate a \fI\s-1META\s0.yml\fR file for your
distribution.
.SS "Module::Install::PAR"
.IX Subsection "Module::Install::PAR"
Makes pre-compiled module binary packages from the built \fIblib\fR
directory, and download existing ones to save recompiling.
.SS "Module::Install::Run"
.IX Subsection "Module::Install::Run"
Determines if commands are available on the user's machine, and runs
them via \fBIPC::Run3\fR.
.SS "Module::Install::Scripts"
.IX Subsection "Module::Install::Scripts"
Handles packaging and installation of scripts to various bin dirs.
.SS "Module::Install::Win32"
.IX Subsection "Module::Install::Win32"
Functions for installing modules on Win32 and finding/installing
\&\fInmake.exe\fR for users that need it.
.SS "Module::Install::WriteAll"
.IX Subsection "Module::Install::WriteAll"
Provides the \f(CW\*(C`WriteAll\*(C'\fR, which writes all the requires files,
such as \fI\s-1META\s0.yml\fR and \fIMakefile\fR.
.PP
\&\f(CW\*(C`WriteAll\*(C'\fR takes four optional named parameters:
.ie n .IP """check_nmake"" (defaults to true)" 4
.el .IP "\f(CWcheck_nmake\fR (defaults to true)" 4
.IX Item "check_nmake (defaults to true)"
If true, invokes functions with the same name.
.Sp
\&\fIThe use of this param is no longer recommended.\fR
.ie n .IP """inline"" (defaults to false)" 4
.el .IP "\f(CWinline\fR (defaults to false)" 4
.IX Item "inline (defaults to false)"
If true, invokes \f(CW\*(C`&Inline\->write\*(C'\fR Inline modules.
.ie n .IP """meta"" (defaults to true)" 4
.el .IP "\f(CWmeta\fR (defaults to true)" 4
.IX Item "meta (defaults to true)"
If true, writes a \f(CW\*(C`META.yml\*(C'\fR file.
.ie n .IP """sign"" (defaults to false)" 4
.el .IP "\f(CWsign\fR (defaults to false)" 4
.IX Item "sign (defaults to false)"
If true, invokes \f(CW\*(C`sign\*(C'\fR command to digitally sign erm... something.
.SS "Module::Install::Admin::Find"

.SH "FAQ"
.IX Header "FAQ"
.SS "What are the benefits of using \fBModule::Install\fP?"
.IX Subsection "What are the benefits of using Module::Install?"
Here is a brief overview of the reasons:
.IP "\(bu" 4
Extremely easy for beginners to learn
.IP "\(bu" 4
Does everything ExtUtils::MakeMaker does.
.IP "\(bu" 4
Does it with a dramatically simpler syntax.
.IP "\(bu" 4
Automatically scans for metadata for you.
.IP "\(bu" 4
Requires no installation for end-users.
.IP "\(bu" 4
Guaranteed forward-compatibility.
.IP "\(bu" 4
Automatically updates your \s-1MANIFEST\s0.
.IP "\(bu" 4
Distributing scripts is easy.
.IP "\(bu" 4
Include prerequisite modules (less dependencies to install)
.IP "\(bu" 4
Auto-installation of prerequisites.
.IP "\(bu" 4
Support for Inline\-based modules.
.IP "\(bu" 4
Support for File::ShareDir shared data files
.IP "\(bu" 4
Support for precompiled \s-1PAR\s0 binaries.
.IP "\(bu" 4
Deals with Win32 install issues for you.
.PP
By greatly shrinking and simplifying the syntax, \fBModule::Install\fR
keeps the amount of work required to maintain your \fIMakefile.PL\fR
files to an absolute minimum.
.PP
And if you maintain more than one module than needs to do unusual
installation tricks, you can create a specific module to abstract
away this complexity.
.SS "Module::Install isn't at 1.00 yet, is it safe to use yet?"
.IX Subsection "Module::Install isn't at 1.00 yet, is it safe to use yet?"
As long as you are going to periodically do incremental releases
to get any bug fixes and new functionality, yes.
.PP
If you don't plan to do incremental releases, it might be a good
idea to continue to wait for a while.
.SH "COOKBOOK / EXAMPLES"
.IX Header "COOKBOOK / EXAMPLES"
The following are some real-life examples of \fIMakefile.PL\fR files
using \fBModule::Install\fR.
.SS "Method::Alias"
.IX Subsection "Method::Alias"
Method::Alias is a trivially-small utility module, with almost the
smallest possible \fIMakefile.PL\fR.
.PP
.Vb 1
\& use inc::Module::Install;
\&
\& name \*(AqMethod\-Alias\*(Aq;
\& all_from \*(Aqlib/Method/Alias.pm\*(Aq;
\& test_requires \*(AqTest::More\*(Aq => \*(Aq0.42\*(Aq;
.Ve
.SS "File::HomeDir"
.IX Subsection "File::HomeDir"
File::HomeDir locates your home directory on any platform. It needs
an installer that can handle different dependencies on different platforms.
.PP
.Vb 1
\& use inc::Module::Install;
\&
\& name \*(AqFile\-HomeDir\*(Aq;
\& all_from \*(Aqlib/File/HomeDir.pm\*(Aq;
\& requires \*(AqFile::Spec\*(Aq => \*(Aq0.80\*(Aq;

\&
\& if ( $MacPerl::Version ) {
\& # Needed on legacy Mac OS 9
\& requires \*(AqMac::Files\*(Aq => 0;
\& }
\&
\& if ( $^O eq \*(AqMXWin32\*(Aq ) {
\& # Needed on Windows platforms
\& requires \*(AqWin32::TieRegistry\*(Aq => 0;
\& }
\&
\& WriteAll;
.Ve
.SH "TO DO"
.IX Header "TO DO"
Implement Module::Install::Compiled and Module::Install::Admin::Compiled
to integrate the Module::Compiled \*(L"perl 6 to perl 5\*(R" functionality with
Module::Install.
Because this would add \s-1SIGNIFICANT\s0 dependencies (i.e. pugs!) this should
almost certainly be distributed as a separate distribution.
.PP
Go over \s-1POD\s0 docs in detail.
.PP
Test recursive Makefile directories
.PP
The test suite needs a great deal more test scripts.
.PP
Dependencies on shared libraries (libxml/libxml.dll etc) and binary files
so that debian/Win32/etc autopackaging applications can create the
appropriate package-level dependencies there.
.PP
\&\s-1EU::MM\s0 6.06_03+ supports \s-1META\s0.yml natively. Maybe probe for that?
