File::Random Version 0.21
=========================
NAME
   File::Random - Perl module for random selecting of a file

INSTALLATION

The classic

   perl Makefile.PL
   make
   make test
   make install

will do this job.

SYNOPSIS
     use File::Random qw/:all/;

     my $fname  = random_file();

     my $fname2 = random_file(-dir => $dir);

     my $random_gif = random_file(-dir       => $dir,
                                  -check     => qr/\.gif$/,
                                  -recursive => 1,
                                  -follow => 1);

     my $no_exe     = random_file(-dir   => $dir,
                                  -check => sub {! -x});

     my @jokes_of_the_day = content_of_random_file(-dir => '/usr/lib/jokes');
     my $joke_of_the_day  = content_of_random_file(-dir => '/usr/lib/jokes');
     # or the shorter
     my $joke = corf(-di r => '/usr/lib/jokes');

     my $word_of_the_day = random_line('/usr/share/dict/words');
     my @three_words     = random_line('/usr/share/dict/words',3);
     # or
     my ($title,$speech,$conclusion) = random_line('/usr/share/dict/words');

DESCRIPTION
   This module simplifies the routine job of selecting a random file. (As
   you can find at CGI scripts).

   It's done, because it's boring (and errorprone), always to write
   something like

     my @files = (<*.*>);
     my $randf = $files[rand @files];

   or

     opendir DIR, " ... " or die " ... ";
     my @files = grep {-f ...} (readdir DIR);
     closedir DIR;
     my $randf = $files[rand @files];

   It also becomes very boring and very dangerous to write randomly
   selection for subdirectory searching with special check-routines.

   The simple standard job of selecting a random line from a file is
   implemented, too.

DEPENDENCIES
 This module requires these other modules and libraries:

   Want

 For the tests are also needed many more modules:

   Test::More
   Test::Exception
   Test::Class
   Set::Scalar
   File::Temp
   Test::Warn
   Test::ManyParams

 All these modules are needed only for the tests.
 You can work with the module even without them.
 These modules are only needed for my test routines,
 not by the File::Random itself.
 (However, it's a good idea most to install most of the modules anyway).
