-# You can customize the captcha engine by providing a Captcha class with this
-# interface:
-# Constructor:
-# Captcha(article) -> constructor, takes an article[1] as argument
-# Attributes:
-# puzzle -> a string with the puzzle the user must solve to prove he is
-# not a bot (can be raw HTML)
-# help -> a string with extra instructions, shown only when the user
-# failed to solve the puzzle
-# Methods:
-# validate(form_data) -> based on the form data[2], returns True if
-# the user has solved the puzzle uccessfully
-# (False otherwise).
-#
-# Note you must ensure that the puzzle attribute and validate() method can
-# "communicate" because they are executed in different requests. You can pass a
-# cookie or just calculate the answer based on the article's data, for example.
-#
-# Example: a captcha class to completely disable the captcha feature
-# class Captcha (object):
-# def __init__(self, article):
-# self.puzzle = ''
-# self.help = ''
-# def validate(form_data):
-# return True
-# Remove the captcha input field from the form template, and that's it!
-#
-# [1] article is an object with all the article's information:
-# path -> string
-# created -> datetime
-# updated -> datetime
-# uuid -> string (unique ID)
-# title -> string
-# author -> string
-# tags -> list of strings
-# raw_contents -> string in rst format
-# comments -> list of Comment objects (not too relevant here)
-# [2] form_data is an object with the form fields (all strings):
-# author, author_error
-# link, link_error
-# catpcha, captcha_error
-# body, body_error
-# action, method
+# Captcha method to use. At the moment only "title" is supported, but if you
+# are keen with Python you can provide your own implementation, see
+# blitiri.cgi for details.
