NAME
       Jifty::LetMe - A way to expose single-link URLs to your applications

   new
       Create a new "LetMe" authentication object; it takes no parameters.  It calls "_init" to do any initialization.

       A LetMe is a way to provide a one-time-use URL for a particular purpose.  All LetMe objects give you a way to validate a user's identity
       and to allow them a very small set of possible actions or page-access permissions.

       For example, you can put a LetMe URL in an email to a new user, so that when they click on the URL you know that their email address is
       valid.

   _init @_
       Called with whatever "new" was called with.  By default, does nothing.

   user
       Contains an app-specific "user" object.

   validated_current_user
       If the user has presented a valid token, returns an (app-specific subclass of the) Jifty::CurrentUser object for the user who has the email
       address in $self->email.  If no user has that email address, returns undef.

   _user_from_email ADDRESS
       Returns an (app-specific subclass of the) Jifty::CurrentUser object for the user who has the email address ADDRESS.

   generate_checksum
       Returns an authentication checksum for the current combination of:

	   user
	   path
	   arguments
	   until

   generate_koremutake_checksum
       Generate a slightly more pronounceable version of the checksum using String::Koremutake.  Due to hex -> integer limitations, this is
       imprecise and may vary depending on the platform it is used on; as such, it is deprecated.

   from_token PATH
       Parse a string of the form

       mylongusername@example.com/update_task/23/until/20050101/bekidrikufryvagygefuba

       into

	     email => mylongusername@example.com,
	     path  => 'update_task/23'
	     until => 20050101,
	     checksum_provided => bekidrikufryvagygefuba

   as_token
       Returns the "letme" token for this set of credentials. This should round trip cleanly with from_token

   as_encoded_token
       A variant of as_token that encodes the user's email address suitably for passing in a URL

   as_url
       Returns the fully qualified URL for this LetMe. It's composed of Jifty->web->url, "base_path" and "as_encoded_token"

   base_path
       By default, all "LetMe" actions live at URLs under '/let' inside your application.  Override this subroutine to change that.

       By default, it returns '/let/'

   validate
       Returns true if the credentials the user presented validate OK.	Returns false otherwise.

   _correct_checksum_provided
       Returns true if the checksum the user provided is correct. Doesn't actually do much input checking. You want to call "validate"
