+Linux / Unix Desktop Fun: Christmas Tree For Your Terminal
+================================================================================
+Let us create Linux or Unix console Christmas tree just for fun and profit. First, you need to install a Perl module called Acme::POE::Tree. It is an animated Christmas tree module. I've tested this on Linux, OS X and Unix-like system.
+
+### Install Acme::POE::Tree ###
+
+The easiest way to install any perl module is to use the cpan (Comprehensive Perl Archive Network). Open the terminal application and type the following command to install Acme::POE::Tree:
+
+    ## run as root ##
+    perl -MCPAN -e 'install Acme::POE::Tree'
+ 
+**Sample outputs:**
+
+    Installing /home/vivek/perl5/man/man3/POE::NFA.3pm
+    Installing /home/vivek/perl5/man/man3/POE::Kernel.3pm
+    Installing /home/vivek/perl5/man/man3/POE::Loop.3pm
+    Installing /home/vivek/perl5/man/man3/POE::Resource.3pm
+    Installing /home/vivek/perl5/man/man3/POE::Filter::Map.3pm
+    Installing /home/vivek/perl5/man/man3/POE::Resource::SIDs.3pm
+    Installing /home/vivek/perl5/man/man3/POE::Loop::IO_Poll.3pm
+    Installing /home/vivek/perl5/man/man3/POE::Pipe::TwoWay.3pm
+    Appending installation info to /home/vivek/perl5/lib/perl5/x86_64-linux-gnu-thread-multi/perllocal.pod
+      RCAPUTO/POE-1.367.tar.gz
+      /usr/bin/make install  -- OK
+      RCAPUTO/Acme-POE-Tree-1.022.tar.gz
+      Has already been unwrapped into directory /home/vivek/.cpan/build/Acme-POE-Tree-1.022-uhlZUz
+      RCAPUTO/Acme-POE-Tree-1.022.tar.gz
+      Has already been prepared
+    Running make for R/RC/RCAPUTO/Acme-POE-Tree-1.022.tar.gz
+    cp lib/Acme/POE/Tree.pm blib/lib/Acme/POE/Tree.pm
+    Manifying 1 pod document
+      RCAPUTO/Acme-POE-Tree-1.022.tar.gz
+      /usr/bin/make -- OK
+    Running make test
+    PERL_DL_NONLAZY=1 "/usr/bin/perl" "-MExtUtils::Command::MM" "-MTest::Harness" "-e" "undef *Test::Harness::Switches; test_harness(0, 'blib/lib', 'blib/arch')" t/*.t
+    t/01_basic.t .. ok
+    All tests successful.
+    Files=1, Tests=2,  6 wallclock secs ( 0.09 usr  0.03 sys +  0.53 cusr  0.06 csys =  0.71 CPU)
+    Result: PASS
+      RCAPUTO/Acme-POE-Tree-1.022.tar.gz
+    Tests succeeded but one dependency not OK (Curses)
+      RCAPUTO/Acme-POE-Tree-1.022.tar.gz
+      [dependencies] -- NA
+
+### Show Christmas tree in the shell ###
+
+Simply type the following command:
+ 
+    perl -MAcme::POE::Tree -e 'Acme::POE::Tree->new()->run()'
+ 
+**Sample outputs:**
+

+
+### Tree customization ###
+
+Here is my tree.pl:
+
+    #!/usr/bin/perl
+     
+    use Acme::POE::Tree;
+    my $tree = Acme::POE::Tree->new(
+    {
+      star_delay => 1.5,  # shimmer star every 1.5 sec
+      light_delay => 2,   # twinkle lights every 2 sec
+      run_for => 10,      # automatically exit after 10 sec
+    }
+    );
+    $tree->run();
+
+Now can play with your tree modifying star_delay, run_for, and light_delay. And ,there you have it a a Christmas tree in your shell for fun.
