.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This document describes version 2 of the \s-1CPAN\s0 distribution metadata
specification, also known as the \*(L"\s-1CPAN\s0 Meta Spec\*(R".
.PP
Revisions of this specification for typo corrections and prose
clarifications may be issued as CPAN::Meta::Spec 2.\fIx\fR.  These
revisions will never change semantics or add or remove specified
behavior.
.PP
Distribution metadata describe important properties of Perl
distributions. Distribution building tools like Module::Build,
Module::Install, ExtUtils::MakeMaker or Dist::Zilla should create a
metadata file in accordance with this specification and include it with
the distribution for use by automated tools that index, examine, package
or install Perl distributions.
.SH "TERMINOLOGY"
.IX Header "TERMINOLOGY"
.IP "distribution" 4
.IX Item "distribution"
This is the primary object described by the metadata. In the context of
this document it usually refers to a collection of modules, scripts,
and/or documents that are distributed together for other developers to
use.  Examples of distributions are \f(CW\*(C`Class\-Container\*(C'\fR, \f(CW\*(C`libwww\-perl\*(C'\fR,
or \f(CW\*(C`DBI\*(C'\fR.
.IP "module" 4
.IX Item "module"
This refers to a reusable library of code contained in a single file.
Modules usually contain one or more packages and are often referred
to by the name of a primary package that can be mapped to the file
name. For example, one might refer to \f(CW\*(C`File::Spec\*(C'\fR instead of
\&\fIFile/Spec.pm\fR
.IP "package" 4
.IX Item "package"
This refers to a namespace declared with the Perl \f(CW\*(C`package\*(C'\fR statement.
In Perl, packages often have a version number property given by the
\&\f(CW$VERSION\fR variable in the namespace.
.IP "consumer" 4
.IX Item "consumer"
This refers to code that reads a metadata file, deserializes it into a
data structure in memory, or interprets a data structure of metadata
elements.
.IP "producer" 4
.IX Item "producer"
This refers to code that constructs a metadata data structure,
serializes into a bytestream and/or writes it to disk.
.IP "must, should, may, etc." 4
.IX Item "must, should, may, etc."
These terms are interpreted as described in \s-1IETF RFC 2119.\s0
.SH "DATA TYPES"
.IX Header "DATA TYPES"
Fields in the \*(L"\s-1STRUCTURE\*(R"\s0 section describe data elements, each of
which has an associated data type as described herein.  There are four
primitive types: Boolean, String, List and Map.  Other types are
subtypes of primitives and define compound data structures or define
constraints on the values of a data element.
.SS "Boolean"
.IX Subsection "Boolean"
A \fIBoolean\fR is used to provide a true or false value.  It \fBmust\fR be
represented as a defined value that is either \*(L"1\*(R" or \*(L"0\*(R" or stringifies
to those values.
.SS "String"
.IX Subsection "String"
A \fIString\fR is data element containing a non-zero length sequence of
Unicode characters, such as an ordinary Perl scalar that is not a
reference.
.SS "List"
.IX Subsection "List"
A \fIList\fR is an ordered collection of zero or more data elements.
Elements of a List may be of mixed types.
.PP
Producers \fBmust\fR represent List elements using a data structure which
unambiguously indicates that multiple values are possible, such as a
reference to a Perl array (an \*(L"arrayref\*(R").
.PP
Consumers expecting a List \fBmust\fR consider a String as equivalent to a
List of length 1.
.SS "Map"
.IX Subsection "Map"
A \fIMap\fR is an unordered collection of zero or more data elements
(\*(L"values\*(R"), indexed by associated String elements (\*(L"keys\*(R").  The Map's
value elements may be of mixed types.
.SS "License String"
.IX Subsection "License String"
A \fILicense String\fR is a subtype of String with a restricted set of
values.  Valid values are described in detail in the description of
the \*(L"license\*(R" field.
.SS "\s-1URL\s0"
.IX Subsection "URL"
\&\fI\s-1URL\s0\fR is a subtype of String containing a Uniform Resource Locator or
Identifier.  [ This type is called \s-1URL\s0 and not \s-1URI\s0 for historical reasons. ]
.SS "Version"
.IX Subsection "Version"
A \fIVersion\fR is a subtype of String containing a value that describes
the version number of packages or distributions.  Restrictions on format
are described in detail in the \*(L"Version Formats\*(R" section.
.SS "Version Range"
.IX Subsection "Version Range"
The \fIVersion Range\fR type is a subtype of String.  It describes a range
of Versions that may be present or installed to fulfill prerequisites.
It is specified in detail in the \*(L"Version Ranges\*(R" section.
.SH "STRUCTURE"
.IX Header "STRUCTURE"
The metadata structure is a data element of type Map.  This section
describes valid keys within the Map.
.PP
Any keys not described in this specification document (whether top-level
or within compound data structures described herein) are considered
\&\fIcustom keys\fR and \fBmust\fR begin with an \*(L"x\*(R" or \*(L"X\*(R" and be followed by an
underscore; i.e. they must match the pattern: \f(CW\*(C`qr{\eAx_}i\*(C'\fR.  If a
custom key refers to a compound data structure, subkeys within it do not
need an \*(L"x_\*(R" or \*(L"X_\*(R" prefix.
.PP
Consumers of metadata may ignore any or all custom keys.  All other keys
not described herein are invalid and should be ignored by consumers.
Producers must not generate or output invalid keys.
.PP
For each key, an example is provided followed by a description.  The
description begins with the version of spec in which the key was added
or in which the definition was modified, whether the key is \fIrequired\fR
or \fIoptional\fR and the data type of the corresponding data element.
These items are in parentheses, brackets and braces, respectively.
.PP
If a data type is a Map or Map subtype, valid subkeys will be described
as well.
.PP
Some fields are marked \fIDeprecated\fR.  These are shown for historical
context and must not be produced in or consumed from any metadata structure
of version 2 or higher.
.SS "\s-1REQUIRED FIELDS\s0"
.IX Subsection "REQUIRED FIELDS"
\fIabstract\fR
.IX Subsection "abstract"
.PP
Example:
.PP
.Vb 1
\&  abstract => \*(AqBuild and install Perl modules\*(Aq
.Ve
.PP
(Spec 1.2) [required] {String}
.PP
This is a short description of the purpose of the distribution.
.PP
\fIauthor\fR
.IX Subsection "author"
.PP
Example:
.PP
.Vb 1
\&  author => [ \*(AqKen Williams <kwilliams@cpan.org>\*(Aq ]
.Ve
.PP
(Spec 1.2) [required] {List of one or more Strings}
.PP
This List indicates the person(s) to contact concerning the
distribution. The preferred form of the contact string is:
.PP
.Vb 1
\&  contact\-name <email\-address>
.Ve
.PP
This field provides a general contact list independent of other
structured fields provided within the \*(L"resources\*(R" field, such as
\&\f(CW\*(C`bugtracker\*(C'\fR.  The addressee(s) can be contacted for any purpose
including but not limited to (security) problems with the distribution,
questions about the distribution or bugs in the distribution.
.PP
A distribution's original author is usually the contact listed within
this field.  Co-maintainers, successor maintainers or mailing lists
devoted to the distribution may also be listed in addition to or instead
of the original author.
.PP
\fIdynamic_config\fR
.IX Subsection "dynamic_config"
.PP
Example:
.PP
.Vb 1
\&  dynamic_config => 1
.Ve
.PP
(Spec 2) [required] {Boolean}
.PP
A boolean flag indicating whether a \fIBuild.PL\fR or \fIMakefile.PL\fR (or
similar) must be executed to determine prerequisites.
.PP
This field should be set to a true value if the distribution performs
some dynamic configuration (asking questions, sensing the environment,
etc.) as part of its configuration.  This field should be set to a false
value to indicate that prerequisites included in metadata may be
considered final and valid for static analysis.
.PP
Note: when this field is true, post-configuration prerequisites are not
guaranteed to bear any relation whatsoever to those stated in the metadata,
and relying on them doing so is an error. See also
\&\*(L"Prerequisites for dynamically configured distributions\*(R" in the implementors'
notes.
.PP
This field explicitly \fBdoes not\fR indicate whether installation may be
safely performed without using a Makefile or Build file, as there may be
special files to install or custom installation targets (e.g. for
dual-life modules that exist on \s-1CPAN\s0 as well as in the Perl core).  This
field only defines whether or not prerequisites are exactly as given in the
metadata.
.PP
\fIgenerated_by\fR
.IX Subsection "generated_by"
.PP
Example:
.PP
.Vb 1
\&  generated_by => \*(AqModule::Build version 0.36\*(Aq
.Ve
.PP
(Spec 1.0) [required] {String}
.PP
This field indicates the tool that was used to create this metadata.
There are no defined semantics for this field, but it is traditional to
use a string in the form \*(L"Generating::Package version 1.23\*(R" or the
author's name, if the file was generated by hand.
.PP
\fIlicense\fR
.IX Subsection "license"
.PP
Example:
.PP
.Vb 1
\&  license => [ \*(Aqperl_5\*(Aq ]
\&
\&  license => [ \*(Aqapache_2_0\*(Aq, \*(Aqmozilla_1_0\*(Aq ]
.Ve
.PP

.PP
(Spec 1.2) [required] {Map}
.PP
This field indicates the version of the \s-1CPAN\s0 Meta Spec that should be
used to interpret the metadata.  Consumers must check this key as soon
as possible and abort further metadata processing if the meta-spec
version is not supported by the consumer.
.PP
The following keys are valid, but only \f(CW\*(C`version\*(C'\fR is required.
.IP "version" 4
.IX Item "version"
This subkey gives the integer \fIVersion\fR of the \s-1CPAN\s0 Meta Spec against
which the document was generated.
.IP "url" 4
.IX Item "url"
This is a \fI\s-1URL\s0\fR of the metadata specification document corresponding to
the given version.  This is strictly for human-consumption and should
not impact the interpretation of the document.

.PP
(Spec 1.0) [required] {String}
.PP
This field is the name of the distribution.  This is often created by
taking the \*(L"main package\*(R" in the distribution and changing \f(CW\*(C`::\*(C'\fR to
\&\f(CW\*(C`\-\*(C'\fR, but the name may be completely unrelated to the packages within
the distribution.  For example, LWP::UserAgent is distributed as part
of the distribution name \*(L"libwww-perl\*(R".

.IX Subsection "release_status"
.PP
Example:
.PP
.Vb 1

.Ve
.PP
(Spec 2) [required] {String}
.PP
This field provides the  release status of this distribution.  If the
\&\f(CW\*(C`version\*(C'\fR field contains an underscore character, then
\&\f(CW\*(C`release_status\*(C'\fR \fBmust not\fR be \*(L"stable.\*(R"
.PP
The \f(CW\*(C`release_status\*(C'\fR field \fBmust\fR have one of the following values:
.IP "stable" 4
.IX Item "stable"
This indicates an ordinary, \*(L"final\*(R" release that should be indexed by \s-1PAUSE\s0
or other indexers.
.IP "testing" 4
.IX Item "testing"
This indicates a \*(L"beta\*(R" release that is substantially complete, but has an
elevated risk of bugs and requires additional testing.  The distribution
should not be installed over a stable release without an explicit request
or other confirmation from a user.  This release status may also be used
for \*(L"release candidate\*(R" versions of a distribution.
.IP "unstable" 4
.IX Item "unstable"
This indicates an \*(L"alpha\*(R" release that is under active development, but has
been released for early feedback or testing and may be missing features or
may have serious bugs.  The distribution should not be installed over a
stable release without an explicit request or other confirmation from a
user.
.PP
Consumers \fBmay\fR use this field to determine how to index the
distribution for \s-1CPAN\s0 or other repositories in addition to or in
replacement of heuristics based on version number or file name.

.IX Subsection "keywords"
.PP
Example:
.PP
.Vb 1

.PP
(Spec 1.1) [optional] {List of zero or more Strings}
.PP
A List of keywords that describe this distribution.  Keywords

.PP
\fIno_index\fR
.IX Subsection "no_index"
.PP
Example:
.PP
.Vb 6
\&  no_index => {

\&    namespace => [ \*(AqMy::Module::Sample\*(Aq ],
\&  }
.Ve
.PP
(Spec 1.2) [optional] {Map}
.PP
This Map describes any files, directories, packages, and namespaces that
are private to the packaging or implementation of the distribution and
should be ignored by indexing or search tools. Note that this is a list of
exclusions, and the spec does not define what to \fIinclude\fR \- see
\&\*(L"Indexing distributions a la \s-1PAUSE\*(R"\s0 in the implementors notes for more
information.
.PP
Valid subkeys are as follows:
.IP "file" 4
.IX Item "file"
A \fIList\fR of relative paths to files.  Paths \fBmust be\fR specified with
unix conventions.
.IP "directory" 4
.IX Item "directory"
A \fIList\fR of relative paths to directories.  Paths \fBmust be\fR specified
with unix conventions.
.Sp
[ Note: previous editions of the spec had \f(CW\*(C`dir\*(C'\fR instead of \f(CW\*(C`directory\*(C'\fR ]
.IP "package" 4
.IX Item "package"
A \fIList\fR of package names.
.IP "namespace" 4
.IX Item "namespace"
A \fIList\fR of package namespaces, where anything below the namespace
must be ignored, but \fInot\fR the namespace itself.
.Sp
In the example above for \f(CW\*(C`no_index\*(C'\fR, \f(CW\*(C`My::Module::Sample::Foo\*(C'\fR would
be ignored, but \f(CW\*(C`My::Module::Sample\*(C'\fR would not.

.Ve
.PP
(Spec 2) [optional] {Map}
.PP
This Map describes optional features with incremental prerequisites.
Each key of the \f(CW\*(C`optional_features\*(C'\fR Map is a String used to identify
the feature and each value is a Map with additional information about
the feature.  Valid subkeys include:
.IP "description" 4
.IX Item "description"
This is a String describing the feature.  Every optional feature
should provide a description
.IP "prereqs" 4
.IX Item "prereqs"
This entry is required and has the same structure as that of the
\&\f(CW"prereqs"\fR key.  It provides a list of package requirements
that must be satisfied for the feature to be supported or enabled.
.Sp
There is one crucial restriction:  the prereqs of an optional feature
\&\fBmust not\fR include \f(CW\*(C`configure\*(C'\fR phase prereqs.
.PP
Consumers \fBmust not\fR include optional features as prerequisites without
explicit instruction from users (whether via interactive prompting,
a function parameter or a configuration value, etc. ).
.PP
If an optional feature is used by a consumer to add additional
prerequisites, the consumer should merge the optional feature
prerequisites into those given by the \f(CW\*(C`prereqs\*(C'\fR key using the same
semantics.  See \*(L"Merging and Resolving Prerequisites\*(R" for details on
merging prerequisites.
.PP
\&\fISuggestion for disuse:\fR Because there is currently no way for a
distribution to specify a dependency on an optional feature of another
dependency, the use of \f(CW\*(C`optional_feature\*(C'\fR is discouraged.  Instead,
create a separate, installable distribution that ensures the desired
feature is available.  For example, if \f(CW\*(C`Foo::Bar\*(C'\fR has a \f(CW\*(C`Baz\*(C'\fR feature,
release a separate \f(CW\*(C`Foo\-Bar\-Baz\*(C'\fR distribution that satisfies
requirements for the feature.

Version numbers must be treated as strings, not numbers.  For

comparison should be delegated to the Perl version module, version

.PP
Unless otherwise specified, version numbers \fBmust\fR appear in one of two

.IP "Decimal versions" 4
.IX Item "Decimal versions"
Decimal versions are regular \*(L"decimal numbers\*(R", with some limitations.
They \fBmust\fR be non-negative and \fBmust\fR begin and end with a digit.  A

.SS "Version Ranges"
.IX Subsection "Version Ranges"
Some fields (prereq, optional_features) indicate the particular
version(s) of some other module that may be required as a prerequisite.
This section details the Version Range type used to provide this
information.
.PP
The simplest format for a Version Range is just the version
number itself, e.g. \f(CW2.4\fR.  This means that \fBat least\fR version 2.4
must be present.  To indicate that \fBany\fR version of a prerequisite is
okay, even if the prerequisite doesn't define a version at all, use
the version \f(CW0\fR.
.PP
Alternatively, a version range \fBmay\fR use the operators < (less than),
<= (less than or equal), > (greater than), >= (greater than
or equal), == (equal), and != (not equal).  For example, the
specification \f(CW\*(C`< 2.0\*(C'\fR means that any version of the prerequisite
less than 2.0 is suitable.
.PP
For more complicated situations, version specifications \fBmay\fR be AND-ed
together using commas.  The specification \f(CW\*(C`>= 1.2, != 1.5, <
2.0\*(C'\fR indicates a version that must be \fBat least\fR 1.2, \fBless than\fR 2.0,
and \fBnot equal to\fR 1.5.
.SH "PREREQUISITES"

.IX Subsection "Prereq Spec"
The \f(CW\*(C`prereqs\*(C'\fR key in the top-level metadata and within
\&\f(CW\*(C`optional_features\*(C'\fR define the relationship between a distribution and
other packages.  The prereq spec structure is a hierarchical data
structure which divides prerequisites into \fIPhases\fR of activity in the
installation process and \fIRelationships\fR that indicate how
prerequisites should be resolved.
.PP
For example, to specify that \f(CW\*(C`Data::Dumper\*(C'\fR is \f(CW\*(C`required\*(C'\fR during the

The configure phase occurs before any dynamic configuration has been
attempted.  Libraries required by the configure phase \fBmust\fR be
available for use before the distribution building tool has been
executed.
.IP "build" 4
.IX Item "build"
The build phase is when the distribution's source code is compiled (if
necessary) and otherwise made ready for installation.
.IP "test" 4
.IX Item "test"
The test phase is when the distribution's automated test suite is run.
Any library that is needed only for testing and not for subsequent use
should be listed here.
.IP "runtime" 4
.IX Item "runtime"
The runtime phase refers not only to when the distribution's contents
are installed, but also to its continued use.  Any library that is a
prerequisite for regular use of this distribution should be indicated
here.
.IP "develop" 4
.IX Item "develop"
The develop phase's prereqs are libraries needed to work on the
distribution's source code as its author does.  These tools might be
needed to build a release tarball, to run author-only tests, or to
perform other tasks related to developing new versions of the
distribution.

These dependencies are optional, but are suggested for enhanced operation

These libraries cannot be installed when the phase is in operation.
This is a very rare situation, and the \f(CW\*(C`conflicts\*(C'\fR relationship should
be used with great caution, or not at all.
.SS "Merging and Resolving Prerequisites"
.IX Subsection "Merging and Resolving Prerequisites"
Whenever metadata consumers merge prerequisites, either from different
phases or from \f(CW\*(C`optional_features\*(C'\fR, they should merged in a way which
preserves the intended semantics of the prerequisite structure.  Generally,
this means concatenating the version specifications using commas, as
described in the \*(L"Version Ranges\*(R" section.
.PP
Another subtle error that can occur in resolving prerequisites comes from
the way that modules in prerequisites are indexed to distribution files on
\&\s-1CPAN. \s0 When a module is deleted from a distribution, prerequisites calling
for that module could indicate an older distribution should be installed,
potentially overwriting files from a newer distribution.
.PP
For example, as of Oct 31, 2009, the \s-1CPAN\s0 index file contained these
module-distribution mappings:
.PP
.Vb 3
\&  Class::MOP                   0.94  D/DR/DROLSKY/Class\-MOP\-0.94.tar.gz
\&  Class::MOP::Class            0.94  D/DR/DROLSKY/Class\-MOP\-0.94.tar.gz
\&  Class::MOP::Class::Immutable 0.04  S/ST/STEVAN/Class\-MOP\-0.36.tar.gz
.Ve
.PP
Consider the case where \*(L"Class::MOP\*(R" 0.94 is installed.  If a
distribution specified \*(L"Class::MOP::Class::Immutable\*(R" as a prerequisite,
it could result in Class\-MOP\-0.36.tar.gz being installed, overwriting
any files from Class\-MOP\-0.94.tar.gz.
.PP
Consumers of metadata \fBshould\fR test whether prerequisites would result
in installed module files being \*(L"downgraded\*(R" to an older version and
\&\fBmay\fR warn users or ignore the prerequisite that would cause such a
result.
.SH "SERIALIZATION"
.IX Header "SERIALIZATION"
Distribution metadata should be serialized (as a hashref) as
JSON-encoded data and packaged with distributions as the file
\&\fI\s-1META\s0.json\fR.
.PP
In the past, the distribution metadata structure had been packed with
distributions as \fI\s-1META\s0.yml\fR, a file in the \s-1YAML\s0 Tiny format (for which,
see YAML::Tiny).  Tools that consume distribution metadata from disk
should be capable of loading \fI\s-1META\s0.yml\fR, but should prefer \fI\s-1META\s0.json\fR
if both are found.
.SH "NOTES FOR IMPLEMENTORS"
.IX Header "NOTES FOR IMPLEMENTORS"
.SS "Extracting Version Numbers from Perl Modules"
.IX Subsection "Extracting Version Numbers from Perl Modules"
To get the version number from a Perl module, consumers should use the
\&\f(CW\*(C`MM\->parse_version($file)\*(C'\fR method provided by
ExtUtils::MakeMaker or Module::Metadata.  For example, for the
module given by \f(CW$mod\fR, the version may be retrieved in one of the
following ways:
.PP
.Vb 3
\&  # via ExtUtils::MakeMaker
\&  my $file = MM\->_installed_file_for_module($mod);
\&  my $version = MM\->parse_version($file)
.Ve
.PP
The private \f(CW\*(C`_installed_file_for_module\*(C'\fR method may be replaced with
other methods for locating a module in \f(CW@INC\fR.
.PP
.Vb 3
\&  # via Module::Metadata
\&  my $info = Module::Metadata\->new_from_module($mod);
\&  my $version = $info\->version;
.Ve
.PP
If only a filename is available, the following approach may be used:
.PP
.Vb 3
\&  # via Module::Build
\&  my $info = Module::Metadata\->new_from_file($file);
\&  my $version = $info\->version;
.Ve
.SS "Comparing Version Numbers"
.IX Subsection "Comparing Version Numbers"
The version module provides the most reliable way to compare version
numbers in all the various ways they might be provided or might exist
within modules.  Given two strings containing version numbers, \f(CW$v1\fR and
\&\f(CW$v2\fR, they should be converted to \f(CW\*(C`version\*(C'\fR objects before using
ordinary comparison operators.  For example:
.PP
.Vb 4
\&  use version;
\&  if ( version\->new($v1) <=> version\->new($v2) ) {
\&    print "Versions are not equal\en";
\&  }
.Ve
.PP
If the only comparison needed is whether an installed module is of a
sufficiently high version, a direct test may be done using the string
form of \f(CW\*(C`eval\*(C'\fR and the \f(CW\*(C`use\*(C'\fR function.  For example, for module \f(CW$mod\fR
and version prerequisite \f(CW$prereq\fR:
.PP
.Vb 3
\&  if ( eval "use $mod $prereq (); 1" ) {
\&    print "Module $mod version is OK.\en";
\&  }
.Ve
.PP
If the values of \f(CW$mod\fR and \f(CW$prereq\fR have not been scrubbed, however,
this presents security implications.
.SS "Prerequisites for dynamically configured distributions"
.IX Subsection "Prerequisites for dynamically configured distributions"
When \f(CW\*(C`dynamic_config\*(C'\fR is true, it is an error to presume that the
prerequisites given in distribution metadata will have any relationship
whatsoever to the actual prerequisites of the distribution.
.PP
In practice, however, one can generally expect such prerequisites to be
one of two things:
.IP "\(bu" 4
The minimum prerequisites for the distribution, to which dynamic configuration will only add items
.IP "\(bu" 4
Whatever the distribution configured with on the releaser's machine at release time
.PP
The second case often turns out to have identical results to the first case,
albeit only by accident.
.PP
As such, consumers may use this data for informational analysis, but
presenting it to the user as canonical or relying on it as such is
invariably the height of folly.
.SS "Indexing distributions a la \s-1PAUSE\s0"
.IX Subsection "Indexing distributions a la PAUSE"
While no_index tells you what must be ignored when indexing, this spec holds
no opinion on how you should get your initial candidate list of things to
possibly index. For \*(L"normal\*(R" distributions you might consider simply indexing
the contents of lib/, but there are many fascinating oddities on \s-1CPAN\s0 and
many dists from the days when it was normal to put the main .pm file in the
root of the distribution archive \- so \s-1PAUSE\s0 currently indexes all .pm and .PL
files that are not either (a) specifically excluded by no_index (b) in
\&\f(CW\*(C`inc\*(C'\fR, \f(CW\*(C`xt\*(C'\fR, or \f(CW\*(C`t\*(C'\fR directories, or common 'mistake' directories such as
\&\f(CW\*(C`perl5\*(C'\fR.
.PP
Or: If you're trying to be PAUSE-like, make sure you skip \f(CW\*(C`inc\*(C'\fR, \f(CW\*(C`xt\*(C'\fR and
\&\f(CW\*(C`t\*(C'\fR as well as anything marked as no_index.
.PP
Also remember: If the \s-1META\s0 file contains a provides field, you shouldn't be
indexing anything in the first place \- just use that.

Ken Williams wrote the original \s-1CPAN\s0 Meta Spec (also known as the
\&\*(L"\s-1META\s0.yml spec\*(R") in 2003 and maintained it through several revisions
with input from various members of the community.  In 2005, Randy
Sims redrafted it from \s-1HTML\s0 to \s-1POD\s0 for the version 1.2 release.  Ken
continued to maintain the spec through version 1.4.
.PP
In late 2009, David Golden organized the version 2 proposal review
