Subject: [PATCH] 	Well, it seems I forgot to add the
 acts_as_authenticated to the repository on my last commit, but they're there
 now. Also, I recently added the Gruff graphing plugin, and created a new
 controller for the graphs, with a method I ported from pollarize to chart how
 many people have voted per day. The basic_login page works, and the create
 user sstem works, but is unpolished and still points to a poem as the index
 page, so if you read a poem, it's supposed to happen. The quickvote creation
 from the homepage is NOT working however, and is about to be investigated.
 I'm not sure how much else isn't working. I noted details abotu
 acts_as_authenticated adn Gruff in the README.

+Handy trick: use the command 'gem_server' from a shell to create a server at 
+http://localhost:8008 that is an easy to navigate locally-hosted website with 
+all the documentation on local gems you have in a easy to read format.
+
+jlsharps: I added the Gruff plug-in today, which is viewable under the folder
+vender/plugins/gruff.  I installed it directly using the Gruff plug-in and
+included controller generate utility. The version 0.1.2, which doesn't seem to
+be the latest version. I've looked into it and it see and it seems that the
+latest version is 0.2.8. However, I wasn't sure how including a gem w/o a plugin 
+would function in end-game rails so I just what I used for now. If you guys 
+(mako of john) know how to do it, it'd probably be better to upgrade, but it 
+didn't seem like the best use of my time right now.  I got the plug-in here:
+http://topfunky.net/svn/plugins/gruff. You can get the gruff gem v 0.2.8 by 
+typing "sudo gem install gruff", I believe it's also hosted on RubyForge. 
+
+I created the GraphsController for Gruff methods to use. In Pollarize I put them 
+in the ApplicationContorller file, so they would be accessible to all. While 
+that it also an option here, it would also mean there wouldn't be much room for 
+playing around because everything in the Application file has to be perfect or 
+it seems to throw Error Code 500 (basically everything breaks). The show() 
+is a sample sample provided with Gruff. 
+
+Documentation is here:http://gruff.rubyforge.org/  Alternately, if you have the 
+gem installed, you can use the ri command, or the above mentioned gem_server. 
+
+If you guys want more helpful stuff here, let me know.

+You must stand the jerking, sorry to say." 
+We "stand it" with oft this painful thought: 
+Are our heads on yet, or are they not? 
+  
+Comrades in misery___let me see; 
+Girl like a statue opposite me; 
+Back and forth the others jostle___ 
+She never winks, nor moves a muscle; 
+See her, as she sits there now; 
+She's "well balanced," anyhow. 
+  
+Woman in trouble, tearful eyes, 
+Sits by the window, softly cries, 
+Pity___for griefs we may not know, 
+For breasts that ache, for tears that flow, 
+Though we know not why. Her eyelids red 
+Tell a sorrowful tale___some hope is dead. 
+  
+Man who follows the Golden Rule, 
+And lends his papers___a pocket full, 
+Has a blank book___once in a minute 
+Has an idea, and writes it in it. 
+Guess him? Yes, of course I can, 
+He's a___well___a newspaper man. 
+  
+Blue-eyed fairy, wrapped in fur; 
+Sweet young mother tending her. 
+Fairy thinks it's "awful far," 
+Wants to get off this "naughty car." 
+So do we, young golden-hair; 
+All this crowd are with you there!

+acts_as_authenticated generator
+====
+
+This is a basic authentication generator for rails, very much in the spirit of xal's original Login Generator.
+
+To use:
+
+  ./script/generate authenticated user account
+
+This generates a basic user model, a controller, some basic views, and tests.  Extra functionality can be unlocked by
+removing the comments for them.  I have a few examples such as user activation and reversible encrypted passwords.
+
+The user migration is also generated unless you pass --skip-migration.
+
+Generate your mailer:
+
+  ./script/generate authenticated_mailer user
+
+Consult the Acts As Authenticated wiki for more: http://technoweenie.stikipad.com/plugins/show/Acts+as+Authenticated

+<h1>In the Caboose.</h1>
+
+<%% content_for 'poem' do -%>
+"Train delayed? and what's to say?" 
+"Blocked by last night's snow they say." 
+Seven hours or so to wait; 
+Well, that's pleasant! but there's the freight. 
+Depot loafing no one fancies, 
+We'll try the caboose and take our chances. 
+  
+Cool this morning in Watertown, 
+Somewhat frosty___mercury down; 
+Enter caboose___roaring fire, 
+With never an air-hole; heat so dire 
+That we shrivel and pant; we are roasted through- 
+Outside, thermometer thirty-two. 
+  
+We start with a jerk and suddenly stop. 
+"What's broke?" says one; another "What's up?", 
+"Oh, nothing," they answer, "That's our way: 
+You must stand the jerking, sorry to say." 
+We "stand it" with oft this painful thought: 
+Are our heads on yet, or are they not? 
+  
+Comrades in misery___let me see; 
+Girl like a statue opposite me; 
+Back and forth the others jostle___ 
+She never winks, nor moves a muscle; 
+See her, as she sits there now; 
+She's "well balanced," anyhow. 
+  
+Woman in trouble, tearful eyes, 
+Sits by the window, softly cries, 
+Pity___for griefs we may not know, 
+For breasts that ache, for tears that flow, 
+Though we know not why. Her eyelids red 
+Tell a sorrowful tale___some hope is dead. 
+  
+Man who follows the Golden Rule, 
+And lends his papers___a pocket full, 
+Has a blank book___once in a minute 
+Has an idea, and writes it in it. 
+Guess him? Yes, of course I can, 
+He's a___well___a newspaper man. 
+  
+Blue-eyed fairy, wrapped in fur; 
+Sweet young mother tending her. 
+Fairy thinks it's "awful far," 
+Wants to get off this "naughty car." 
+So do we, young golden-hair; 
+All this crowd are with you there!
