#pod L<Module::Build>.
#pod
#pod =cut
#pod =attr mb_version
#pod
#pod B<Optional:> Specify the minimum version of L<Module::Build> to depend on.
#pod
#pod Defaults to 0.3601 if a sharedir is being used, otherwise 0.28.
#pod
#pod =attr mb_class
#pod
#pod B<Optional:> Specify the class to use to create the build object.  Defaults
#pod to C<Module::Build> itself.  If another class is specified, then the value
#pod of mb_lib will be used to generate a line like C<use lib 'inc'> to be added
#pod to the generated Build.PL file.
#pod
#pod =attr mb_lib
#pod
#pod B<Optional:> Specify the list of directories to be passed to lib when using 
#pod mb_class. Defaults to C<inc>. 
#pod
#pod =attr build_element
#pod
#pod Anything given in a C<build_element> option will be added as a build element
#pod with Module::Build's L<add_build_element> method.

=head1 NAME
Dist::Zilla::Plugin::ModuleBuild - build a Build.PL that uses Module::Build
=head1 VERSION
version 6.032
=head1 DESCRIPTION
This plugin will create a F<Build.PL> for installing the dist using
L<Module::Build>.
=head1 PERL VERSION
This module should work on any version of perl still receiving updates from
the Perl 5 Porters.  This means it should work on any version of perl
released in the last two to three years.  (That is, if the most recently
released version is v5.40, then this module should work on both v5.40 and
v5.38.)
Although it may work on older versions of perl, no guarantee is made that the
minimum required version will not be increased.  The version may be increased
for any reason, and there is no promise that patches will be accepted to
lower the minimum required perl.
=head1 ATTRIBUTES
=head2 mb_version
B<Optional:> Specify the minimum version of L<Module::Build> to depend on.
Defaults to 0.3601 if a sharedir is being used, otherwise 0.28.
=head2 mb_class
B<Optional:> Specify the class to use to create the build object.  Defaults
to C<Module::Build> itself.  If another class is specified, then the value
of mb_lib will be used to generate a line like C<use lib 'inc'> to be added
to the generated Build.PL file.
=head2 mb_lib
B<Optional:> Specify the list of directories to be passed to lib when using 
mb_class. Defaults to C<inc>. 
=head2 build_element
Anything given in a C<build_element> option will be added as a build element
with Module::Build's L<add_build_element> method.
