-# This script aims to help developers locate forms and view code that needs to
-# use the new CSRF protection in Django 1.2.  It tries to find all the code that
-# may need the steps described in the CSRF documentation.  It does not modify
-# any code directly, it merely attempts to locate it.  Developers should be
-# aware of its limitations, described below.
-#
-# For each template that contains at least one POST form, the following info is printed:
-#
-# <Absolute path to template>
-#   AKA: <Aliases (relative to template directory/directories that contain it)>
-#   POST forms: <Number of POST forms>
-#   With token: <Number of POST forms with the CSRF token already added>
-#   Without token:
-#     <File name and line number of form without token>
-#
-#   Searching for:
-#     <Template names that need to be searched for in view code
-#      (includes templates that 'include' current template)>
-#
-#   Found:
-#     <File name and line number of any view code found>
-#
-# The format used allows this script to be used in Emacs grep mode:
-#   M-x grep
-#   Run grep (like this): /path/to/my/virtualenv/python /path/to/django/src/extras/csrf_migration_helper.py --settings=mysettings /path/to/my/srcs
-
-
-# Limitations
-# ===========
-#
-# - All templates must be stored on disk in '.html' or '.htm' files.
-#   (extensions configurable below)
-#
-# - All Python code must be stored on disk in '.py' files.  (extensions
-#   configurable below)
-#
-# - All templates must be accessible from TEMPLATE_DIRS or from the 'templates/'
-#   directory in apps specified in INSTALLED_APPS.  Non-file based template
-#   loaders are out of the picture, because there is no way to ask them to
-#   return all templates.
-#
-# - If you put the {% csrf_token %} tag on the same line as the <form> tag it
-#   will be detected, otherwise it will be assumed that the form does not have
-#   the token.
-#
-# - It's impossible to programmatically determine which forms should and should
-#   not have the token added.  The developer must decide when to do this,
-#   ensuring that the token is only added to internally targetted forms.
-#
-# - It's impossible to programmatically work out when a template is used.  The
-#   attempts to trace back to view functions are guesses, and could easily fail
-#   in the following ways:
-#
-#   * If the 'include' template tag is used with a variable
-#     i.e. {% include tname %} where tname is a variable containing the actual
-#     template name, rather than {% include "my_template.html" %}.
-#
-#   * If the template name has been built up by view code instead of as a simple
-#     string.  For example, generic views and the admin both do this.  (These
-#     apps are both contrib and both use RequestContext already, as it happens).
-#
-#   * If the 'ssl' tag (or any template tag other than 'include') is used to
-#     include the template in another template.
-#
-# - All templates belonging to apps referenced in INSTALLED_APPS will be
-#   searched, which may include third party apps or Django contrib.  In some
-#   cases, this will be a good thing, because even if the templates of these
-#   apps have been fixed by someone else, your own view code may reference the
-#   same template and may need to be updated.
-#
-#   You may, however, wish to comment out some entries in INSTALLED_APPS or
-#   TEMPLATE_DIRS before running this script.
-
-# Improvements to this script are welcome!

-    ]
-
-TEMPLATE_ENCODING = "UTF-8"
-
-PYTHON_ENCODING = "UTF-8"
-
-# Method
-# ======
-
-# Find templates:
-#  - template dirs
-#  - installed apps
-#
-# Search for POST forms
-#  - Work out what the name of the template is, as it would appear in an
-#    'include' or get_template() call. This can be done by comparing template
-#    filename to all template dirs.  Some templates can have more than one
-#    'name' e.g.  if a directory and one of its child directories are both in
-#    TEMPLATE_DIRS.  This is actually a common hack used for
-#    overriding-and-extending admin templates.
-#
-# For each POST form,
-# - see if it already contains '{% csrf_token %}' immediately after <form>
-# - work back to the view function(s):
-#   - First, see if the form is included in any other templates, then
-#     recursively compile a list of affected templates.
-#   - Find any code function that references that template.  This is just a
-#     brute force text search that can easily return false positives
-#     and fail to find real instances.
