+Authentication methods for Haskell web applications.
+
+Note for Rpxnow: 
+By default on some (all?) installs wget does not come with root certificates
+for SSL.  If this is the case then Web.Authenticate.Rpxnow.authenticate will
+fail as wget cannot establish a secure connection to rpxnow's servers.
+
+A simple *nix solution, if potentially insecure (man in the middle attacks as
+you are downloading the certs) is to grab a copy of the certs extracted from
+those that come with firefox, hosted by CURL at
+http://curl.haxx.se/ca/cacert.pem , put them somewhere (for ex,
+~/.wget/cacert.pem) and then edit your ~/.wgetrc to include:
+ca_certificate=~/.wget/cacert.pem
+
+This should fix the problem.

 # Yesod Web Framework
 
@@ -12,50 +12,20 @@ An advanced web framework using the Haskell programming language. Featuring:
   * asynchronous IO
     * this is built in to the Haskell programming language (like Erlang)
 
-## Getting Started
-
 Learn more about Yesod on [its main website](http://www.yesodweb.com/). If you
 want to get started using Yesod, we strongly recommend the [quick start
 guide](http://www.yesodweb.com/page/quickstart), based on [the Haskell build
 tool stack](https://github.com/commercialhaskell/stack#readme).
 
-Here's a minimal example!
-
-```haskell
-{-# LANGUAGE OverloadedStrings, QuasiQuotes, TemplateHaskell, TypeFamilies #-}
-
-import Yesod
-
-data App = App -- Put your config, database connection pool, etc. in here.
-
--- Derive routes and instances for App.
-mkYesod "App" [parseRoutes|
-/ HomeR GET
-|]
-
-instance Yesod App -- Methods in here can be overridden as needed.
-
--- The handler for the GET request at /, corresponds to HomeR.
-getHomeR :: Handler Html
-getHomeR = defaultLayout [whamlet|Hello World!|]
-
-main :: IO ()
-main = warp 3000 App
-```
-
-To read about each of the concepts in use above (routing, handlers,
-linking, JSON), in detail, visit
-[Basics in the Yesod book](https://www.yesodweb.com/book/basics#basics_routing).
-
 ## Hacking on Yesod
 
 Yesod consists mostly of four repositories:
 
 ```bash
-git clone --recurse-submodules http://github.com/yesodweb/shakespeare
+git clone --recursive http://github.com/yesodweb/shakespeare
-git clone --recurse-submodules http://github.com/yesodweb/persistent
+git clone --recursive http://github.com/yesodweb/persistent
-git clone --recurse-submodules http://github.com/yesodweb/wai
+git clone --recursive http://github.com/yesodweb/wai
-git clone --recurse-submodules http://github.com/yesodweb/yesod
+git clone --recursive http://github.com/yesodweb/yesod
 ```
 
 Each repository can be built with `stack build`.

--- | Use an email address as an identifier via Google's login system.
---
--- Note that this is a replacement for "Yesod.Auth.GoogleEmail", which depends
--- on Google's now deprecated OpenID system. For more information, see
--- <https://developers.google.com/+/api/auth-migration>.
---
--- By using this plugin, you are trusting Google to validate an email address,
--- and requiring users to have a Google account. On the plus side, you get to
--- use email addresses as the identifier, many users have existing Google
--- accounts, the login system has been long tested (as opposed to BrowserID),
--- and it requires no credential managing or setup (as opposed to Email).
---
--- In order to use this plugin:
---
--- * Create an application on the Google Developer Console <https://console.developers.google.com/>
---
--- * Create OAuth credentials. The redirect URI will be <http://yourdomain/auth/page/googleemail2/complete>. (If you have your authentication subsite at a different root than \/auth\/, please adjust accordingly.)
---
--- * Enable the Google+ API.

-## 1.6.23.1
-
-* Fix typo in creation of the description `<meta>` tag in `defaultLayout`. [#1766](https://github.com/yesodweb/yesod/pull/1766)
-
-## 1.6.23
-
-* Add idempotent versions of `setDescription`, `setDescriptionI`. These functions
-  have odd behaviour when called multiple times, so they are now warned against.
-  This can't be a silent change - if you want to switch to the new functions, make
-  sure your layouts are updated to use `pageDescription` as well as `pageTitle`.
-  [#1765](https://github.com/yesodweb/yesod/pull/1765)

-
-* Add missing list to documentation for ``Yesod.Core.Dispatch.warp``. [#1745](https://github.com/yesodweb/yesod/pull/1745)
-* Add instances for `ToContent Void`, `ToTypedContent Void`. [#1752](https://github.com/yesodweb/yesod/pull/1752)
-* Handle async exceptions within yesod rather then warp. [#1753](https://github.com/yesodweb/yesod/pull/1753)
-* Support template-haskell 2.18 [#1754](https://github.com/yesodweb/yesod/pull/1754)
-
-## 1.6.21.0
-
-* Export `Yesod.Core.Dispatch.defaultGen` so that users may reuse it for their own `YesodRunnerEnv`s [#1734](https://github.com/yesodweb/yesod/pull/1734)

-
-## 1.6.18.3

--- | The general structure of each individually generated field is as follows.
--- There is an external wrapper element containing both an inner wrapper and any
--- error messages that apply to that specific field. The inner wrapper contains
--- both the field and it's corresponding delete button.
---
--- The structure is illustrated by the following:
--- 
--- > <div .#{wrapperClass}>
--- >     <div .#{wrapperClass}-inner>
--- >         ^{fieldWidget}
--- >         ^{deleteButton}
--- >     ^{maybeErrorMessages}
---
--- Each wrapper element has the same class which is automatically generated. This class
--- is returned in the 'MultiView' should you wish to change the styling. The inner wrapper
--- uses the same class followed by @-inner@. By default the wrapper and inner wrapper has
--- classes are as follows:
--- 
--- > .#{wrapperClass} {
--- >     margin-bottom: 1rem;
--- > }
--- >
--- > .#{wrapperClass}-inner {
--- >     display: flex;
--- >     flex-direction: row;
--- > }
