=head1 NAME
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} );
