+=head1 NAME
+
+CPAN::Meta::Requirements - a set of version requirements for a CPAN dist
+
+=head1 VERSION
+
+version 2.113640
+
+=head1 SYNOPSIS
+
+ use CPAN::Meta::Requirements;
+
+ my $build_requires = CPAN::Meta::Requirements->new;
+
+ $build_requires->add_minimum('Library::Foo' => 1.208);
+
+ $build_requires->add_minimum('Library::Foo' => 2.602);
+
+ $build_requires->add_minimum('Module::Bar' => 'v1.2.3');
+
+ $METAyml->{build_requires} = $build_requires->as_string_hash;
+
+=head1 DESCRIPTION
+
+A CPAN::Meta::Requirements object models a set of version constraints like
+those specified in the F<META.yml> or F<META.json> files in CPAN distributions.
+It can be built up by adding more and more constraints, and it will reduce them
+to the simplest representation.
+
+Logically impossible constraints will be identified immediately by thrown
+exceptions.
+
+=head1 METHODS
+
+=head2 new
+
+ my $req = CPAN::Meta::Requirements->new;
+
+This returns a new CPAN::Meta::Requirements object. It ignores any arguments
+given.
+
+=head2 add_minimum
+
+ $req->add_minimum( $module => $version );
+
+This adds a new minimum version requirement. If the new requirement is
+redundant to the existing specification, this has no effect.
+
+Minimum requirements are inclusive. C<$version> is required, along with any
+greater version number.
+
+This method returns the requirements object.
+
+=head2 add_maximum
+
+ $req->add_maximum( $module => $version );
+
+This adds a new maximum version requirement. If the new requirement is
+redundant to the existing specification, this has no effect.
+
+Maximum requirements are inclusive. No version strictly greater than the given
+version is allowed.
+
+This method returns the requirements object.
+
+=head2 add_exclusion
+
+ $req->add_exclusion( $module => $version );
+
+This adds a new excluded version. For example, you might use these three
+method calls:
+
+ $req->add_minimum( $module => '1.00' );
+ $req->add_maximum( $module => '1.82' );
+
+ $req->add_exclusion( $module => '1.75' );
+
+Any version between 1.00 and 1.82 inclusive would be acceptable, except for
+1.75.
+
+This method returns the requirements object.
+
+=head2 exact_version
+
+ $req->exact_version( $module => $version );
+
+This sets the version required for the given module to I<exactly> the given
+version. No other version would be considered acceptable.
+
+This method returns the requirements object.
+
+=head2 add_requirements
+
+ $req->add_requirements( $another_req_object );
+
+This method adds all the requirements in the given CPAN::Meta::Requirements object
+to the requirements object on which it was called. If there are any conflicts,
+an exception is thrown.
+
+This method returns the requirements object.
+
+=head2 accepts_module
+
+ my $bool = $req->accepts_modules($module => $version);
+
+Given an module and version, this method returns true if the version
+specification for the module accepts the provided version. In other words,
+given:
+
+ Module => '>= 1.00, < 2.00'
+
+We will accept 1.00 and 1.75 but not 0.50 or 2.00.
+
+For modules that do not appear in the requirements, this method will return
+true.
+
+=head2 clear_requirement
+
+ $req->clear_requirement( $module );
+
+This removes the requirement for a given module from the object.
+
+This method returns the requirements object.
+
+=head2 required_modules
+
+This method returns a list of all the modules for which requirements have been
+specified.
+
+=head2 clone
+
+ $req->clone;
+
+This method returns a clone of the invocant. The clone and the original object
+can then be changed independent of one another.
+
+=head2 is_simple
+
+This method returns true if and only if all requirements are inclusive minimums
+-- that is, if their string expression is just the version number.
+
+=head2 is_finalized
+
+This method returns true if the requirements have been finalized by having the
+C<finalize> method called on them.
+
+=head2 finalize
+
+This method marks the requirements finalized. Subsequent attempts to change
+the requirements will be fatal, I<if> they would result in a change. If they
+would not alter the requirements, they have no effect.
+
+If a finalized set of requirements is cloned, the cloned requirements are not
+also finalized.
+
+=head2 as_string_hash
+
+This returns a reference to a hash describing the requirements using the
+strings in the F<META.yml> specification.
+
+For example after the following program:
+
+ my $req = CPAN::Meta::Requirements->new;
+
+ $req->add_minimum('CPAN::Meta::Requirements' => 0.102);
+
+ $req->add_minimum('Library::Foo' => 1.208);
+
+ $req->add_maximum('Library::Foo' => 2.602);
+
+ $req->add_minimum('Module::Bar' => 'v1.2.3');
+
+ $req->add_exclusion('Module::Bar' => 'v1.2.8');
+
+ $req->exact_version('Xyzzy' => '6.01');
+
+ my $hashref = $req->as_string_hash;
+
+C<$hashref> would contain:
+
+ {
+ 'CPAN::Meta::Requirements' => '0.102',
+ 'Library::Foo' => '>= 1.208, <= 2.206',
+ 'Module::Bar' => '>= v1.2.3, != v1.2.8',
+ 'Xyzzy' => '== 6.01',
+ }
+
+=head2 from_string_hash
+
+ my $req = CPAN::Meta::Requirements->from_string_hash( \%hash );
+
+This is an alternate constructor for a CPAN::Meta::Requirements object. It takes
+a hash of module names and version requirement strings and returns a new
+CPAN::Meta::Requirements object.
