=head1 NAME
Dist::Zilla::Util - random snippets of code that Dist::Zilla wants
=head1 VERSION
version 6.032
=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 METHODS
=head2 abstract_from_file
This method, I<which is likely to change or go away>, tries to guess the
abstract of a given file, assuming that it's Perl code.  It looks for a POD
C<=head1> section called "NAME" or a comment beginning with C<ABSTRACT:>.
=head2 expand_config_package_name
  my $pkg_name = Dist::Zilla::Util->expand_config_package_name($string);
This method, I<which is likely to change or go away>, rewrites the given string
into a package name.
Prefixes are rewritten as follows:
=over 4
=item *
C<=> becomes nothing
=item *
C<@> becomes C<Dist::Zilla::PluginBundle::>
=item *
C<%> becomes C<Dist::Zilla::Stash::>
