File::Find::Rule::Procedural - File::Find::Rule's procedural interface

=head1 SYNOPSIS

  use File::Find::Rule;

  # find all .pm files, procedurally
  my @files = find(file => name => '*.pm', in => \@INC);

=head1 DESCRIPTION

In addition to the regular object-oriented interface,
L<File::Find::Rule> provides two subroutines for you to use.

=over

=item C<find( @clauses )>

=item C<rule( @clauses )>

C<find> and C<rule> can be used to invoke any methods available to the
OO version.  C<rule> is a synonym for C<find>

=back

Passing more than one value to a clause is done with an anonymous
array:

 my $finder = find( name => [ '*.mp3', '*.ogg' ] );

C<find> and C<rule> both return a File::Find::Rule instance, unless
one of the arguments is C<in>, in which case it returns a list of
things that match the rule.

 my @files = find( name => [ '*.mp3', '*.ogg' ], in => $ENV{HOME} );

Please note that C<in> will be the last clause evaluated, and so this
code will search for mp3s regardless of size.

 my @files = find( name => '*.mp3', in => $ENV{HOME}, size => '<2k' );
                                                    ^
                                                    |
               Clause processing stopped here ------/

It is also possible to invert a single rule by prefixing it with C<!>
like so:

 # large files that aren't videos
 my @files = find( file    =>
                   '!name' => [ '*.avi', '*.mov' ],
                   size    => '>20M',
                   in      => $ENV{HOME} );
