-_Flips CSS from LTR to an RTL orienation and vice-versa_
-
-Author: `Lindsey Simon <elsigh@google.com>`
-
-==Introduction==
-
-CSSJanus is CSS parser utility designed to aid the conversion of a website's
-layout from left-to-right(LTR) to right-to-left(RTL). The script was born out of
-a need to convert CSS for RTL languages when tables are not being used for layout (since tables will automatically reorder TD's in RTL).
-CSSJanus will change most of the obvious CSS property names and their values as
-well as some not-so-obvious ones (cursor, background-position %, etc...).
-The script is designed to offer flexibility to account for cases when you do
-not want to change certain rules which exist to account for bidirectional text
-display bugs, as well as situations where you may or may not want to flip annotations inside of the background url string.
-Note that you can disable CSSJanus from running on an entire class or any
-rule within a class by prepending a /* @noflip */ comment before the rule(s)
-you want CSSJanus to ignore.
-
-CSSJanus itself is not always enough to make a website that works in a LTR
-language context work in a RTL language all the way, but it is a start.
-
-==Getting the code==
-
-View the trunk at:
-
-  http://cssjanus.googlecode.com/svn/trunk/
-
-Check out the latest development version anonymously with:
-
-{{{
-  $ svn checkout http://cssjanus.googlecode.com/svn/trunk/ cssjanus
-}}}
-
-==Using==
-
-Usage:
-  ./cssjanus.py < file.css > file-rtl.css
-Flags:
-  --swap_left_right_in_url: Fixes "left"/"right" string within urls.
-  Ex: ./cssjanus.py --swap_left_right_in_url < file.css > file_rtl.css
-  --swap_ltr_rtl_in_url: Fixes "ltr"/"rtl" string within urls.
-  Ex: ./cssjanus.py --swap_ltr_rtl_in_url < file.css > file_rtl.css
-
-If you'd like to make use of the webapp version of cssjanus, you'll need to
-download the Google App Engine SDK
-  http://code.google.com/appengine/downloads.html
-and also drop a "django" directory into this directory, with the latest svn
-from django. You should be good to go with that setup. Please let me know
-otherwise.
-
-==Bugs, Patches==
-
-Patches and bug reports are welcome, just please keep the style
-consistent with the original source. If you find a bug, please include a diff
-of cssjanus_test.py with the bug included as a new unit test which fails. It
-will make understanding and fixing the bug easier.
-
-==Todo==
-
-* Include some helpers for some typical bidi text solutions?
-* Aural CSS (azimuth) swapping?
-
-==Contributors==
-
-Additional thanks to Mike Samuel for his work on csslex.py, Andy Perelson for
-his help coding and reviewing, Stephen Zabel for his help with i18n and my sanity,
-and to Eric Meyer for his thoughtful input.
-Thanks to Junyu Wang for the Chinese translation.
-Thanks to Masashi Kawashima for the Japanese translation.
-Thanks to Taaryk Taar and Tariq Al-Omaireeni for an updated Arabic translation.
-Thanks to Jens Meiert for the German translation.

-"""Converts a LeftToRight Cascading Style Sheet into a RightToLeft one.
-
-   This is a utility script for replacing "left" oriented things in a CSS file
-   like float, padding, margin with "right" oriented values.
-   It also does the opposite.
-   The goal is to be able to conditionally serve one large, cat'd, compiled CSS
-   file appropriate for LeftToRight oriented languages and RightToLeft ones.
-   This utility will hopefully help your structural layout done in CSS in
-   terms of its RTL compatibility. It will not help with some of the more
-   complicated bidirectional text issues.
