+Jinja
+=====
+
+Jinja is a fast, expressive, extensible templating engine. Special
+placeholders in the template allow writing code similar to Python
+syntax. Then the template is passed data to render the final document.
+
+It includes:
+
+-   Template inheritance and inclusion.
+-   Define and import macros within templates.
+-   HTML templates can use autoescaping to prevent XSS from untrusted
+    user input.
+-   A sandboxed environment can safely render untrusted templates.
+-   AsyncIO support for generating templates and calling async
+    functions.
+-   I18N support with Babel.
+-   Templates are compiled to optimized Python code just-in-time and
+    cached, or can be compiled ahead-of-time.
+-   Exceptions point to the correct line in templates to make debugging
+    easier.
+-   Extensible filters, tests, functions, and even syntax.
+
+Jinja's philosophy is that while application logic belongs in Python if
+possible, it shouldn't make the template designer's job difficult by
+restricting functionality too much.
+
+

+MarkupSafe
+==========
+
+MarkupSafe implements a text object that escapes characters so it is
+safe to use in HTML and XML. Characters that have special meanings are
+replaced so that they display as the actual characters. This mitigates
+injection attacks, meaning untrusted user input can safely be displayed
+on a page.
+
+
+Installing
+----------
+
+Install and update using `pip`_:
+
+.. code-block:: text
+
+    pip install -U MarkupSafe
+
+.. _pip: https://pip.pypa.io/en/stable/getting-started/
+
+
+Examples
+--------
+
+.. code-block:: pycon
+
+    >>> from markupsafe import Markup, escape
+
+    >>> # escape replaces special characters and wraps in Markup
+    >>> escape("<script>alert(document.cookie);</script>")
+    Markup('&lt;script&gt;alert(document.cookie);&lt;/script&gt;')
+
+    >>> # wrap in Markup to mark text "safe" and prevent escaping
+    >>> Markup("<strong>Hello</strong>")
+    Markup('<strong>hello</strong>')
+
+    >>> escape(Markup("<strong>Hello</strong>"))
+    Markup('<strong>hello</strong>')
+
+    >>> # Markup is a str subclass
+    >>> # methods and operators escape their arguments
+    >>> template = Markup("Hello <em>{name}</em>")
+    >>> template.format(name='"World"')
+    Markup('Hello <em>&#34;World&#34;</em>')

+
+BLP1 files, used mostly in Warcraft III, are not fully supported.
+All types of BLP2 files used in World of Warcraft are supported.
+
+The BLP file structure consists of a header, up to 16 mipmaps of the
+texture
+
+Texture sizes must be powers of two, though the two dimensions do
+not have to be equal; 512x256 is valid, but 512x200 is not.
+The first mipmap (mipmap #0) is the full size image; each subsequent
+mipmap halves both dimensions. The final mipmap should be 1x1.
+
+BLP files come in many different flavours:
+* JPEG-compressed (type == 0) - only supported for BLP1.
+* RAW images (type == 1, encoding == 1). Each mipmap is stored as an
+  array of 8-bit values, one per pixel, left to right, top to bottom.
+  Each value is an index to the palette.
+* DXT-compressed (type == 1, encoding == 2):
+- DXT1 compression is used if alpha_encoding == 0.
+  - An additional alpha bit is used if alpha_depth == 1.
+  - DXT3 compression is used if alpha_encoding == 1.
+  - DXT5 compression is used if alpha_encoding == 7.

+Independence War 2: Edge Of Chaos - Texture File Format - 16 October 2001
+
+The textures used for 3D objects in Independence War 2: Edge Of Chaos are in a
+packed custom format called FTEX. This file format uses file extensions FTC
+and FTU.
+* FTC files are compressed textures (using standard texture compression).
+* FTU files are not compressed.
+Texture File Format
+The FTC and FTU texture files both use the same format. This
+has the following structure:
+{header}
+{format_directory}
+{data}
+Where:
+{header} = {
+    u32:magic,
+    u32:version,
+    u32:width,
+    u32:height,
+    u32:mipmap_count,
+    u32:format_count
+}
+
+* The "magic" number is "FTEX".
+* "width" and "height" are the dimensions of the texture.
+* "mipmap_count" is the number of mipmaps in the texture.
+* "format_count" is the number of texture formats (different versions of the
+same texture) in this file.
+
+{format_directory} = format_count * { u32:format, u32:where }
+
+The format value is 0 for DXT1 compressed textures and 1 for 24-bit RGB
+uncompressed textures.
+The texture data for a format starts at the position "where" in the file.
+
+Each set of texture data in the file has the following structure:
+{data} = format_count * { u32:mipmap_size, mipmap_size * { u8 } }
+* "mipmap_size" is the number of bytes in that mip level. For compressed
+textures this is the size of the texture data compressed with DXT1. For 24 bit
+uncompressed textures, this is 3 * width * height. Following this are the image
+bytes for that mipmap level.
+
+Note: All data is stored in little-Endian (Intel) byte order.

+
+    Originally released under LGPL.  Graciously donated to PIL in
+    March 2009, for distribution under the standard PIL license
+
+    The pyCMS.py module provides a "clean" interface between Python/PIL and
+    pyCMSdll, taking care of some of the more complex handling of the direct
+    pyCMSdll functions, as well as error-checking and making sure that all
+    relevant data is kept together.
+
+    While it is possible to call pyCMSdll functions directly, it's not highly
+    recommended.
+
+    Version History:
+
+        1.0.0 pil       Oct 2013 Port to LCMS 2.
+
+        0.1.0 pil mod   March 10, 2009
+
+                        Renamed display profile to proof profile. The proof
+                        profile is the profile of the device that is being
+                        simulated, not the profile of the device which is
+                        actually used to display/print the final simulation
+                        (that'd be the output profile) - also see LCMSAPI.txt
+                        input colorspace -> using 'renderingIntent' -> proof
+                        colorspace -> using 'proofRenderingIntent' -> output
+                        colorspace
+
+                        Added LCMS FLAGS support.
+                        Added FLAGS["SOFTPROOFING"] as default flag for
+                        buildProofTransform (otherwise the proof profile/intent
+                        would be ignored).
+
+        0.1.0 pil       March 2009 - added to PIL, as PIL.ImageCms
+
+        0.0.2 alpha     Jan 6, 2002
+
+                        Added try/except statements around type() checks of
+                        potential CObjects... Python won't let you use type()
+                        on them, and raises a TypeError (stupid, if you ask
+                        me!)
+
+                        Added buildProofTransformFromOpenProfiles() function.
+                        Additional fixes in DLL, see DLL code for details.

+# History:
+# 1996-04-13 fl   Created (experimental)
+# 1996-08-07 fl   Filled polygons, ellipses.
+# 1996-08-13 fl   Added text support
+# 1998-06-28 fl   Handle I and F images
+# 1998-12-29 fl   Added arc; use arc primitive to draw ellipses
+# 1999-01-10 fl   Added shape stuff (experimental)
+# 1999-02-06 fl   Added bitmap support
+# 1999-02-11 fl   Changed all primitives to take options
+# 1999-02-20 fl   Fixed backwards compatibility
+# 2000-10-12 fl   Copy on write, when necessary
+# 2001-02-18 fl   Use default ink for bitmap/text also in fill mode
+# 2002-10-24 fl   Added support for CSS-style color strings
+# 2002-12-10 fl   Added experimental support for RGBA-on-RGB drawing
+# 2002-12-11 fl   Refactored low-level drawing API (work in progress)
+# 2004-08-26 fl   Made Draw() a factory function, added getdraw() support
+# 2004-09-04 fl   Added width support to line primitive
+# 2004-09-10 fl   Added font mode handling
+# 2006-06-19 fl   Added font bearing support (getmask2)
