+krTheme Sphinx Style
+====================
+
+This repository contains sphinx styles Kenneth Reitz uses in most of 
+his projects. It is a drivative of Mitsuhiko's themes for Flask and Flask related
+projects.  To use this style in your Sphinx documentation, follow
+this guide:
+
+1. put this folder as _themes into your docs folder.  Alternatively
+   you can also use git submodules to check out the contents there.
+
+2. add this to your conf.py: ::
+
+	sys.path.append(os.path.abspath('_themes'))
+	html_theme_path = ['_themes']
+	html_theme = 'flask'
+
+The following themes exist:
+
+**kr**
+	the standard flask documentation theme for large projects
+
+**kr_small**
+	small one-page theme.  Intended to be used by very small addon libraries.

+Design Considerations
+---------------------
+
+Tablib was developed with a few :pep:`20` idioms in mind.
+
+#. Beautiful is better than ugly.
+#. Explicit is better than implicit.
+#. Simple is better than complex.
+#. Complex is better than complicated.
+#. Readability counts.

+#. Keep your code DRY.
+#. Strive to be as simple (to use) as possible.

+------------------
+Adding New Formats
+------------------
+
+Tablib welcomes new format additions! Format suggestions include:
+
+* Tab Seperated Values
+* MySQL Dump
+* HTML Table
+
+
+Coding by Convention
+++++++++++++++++++++
+
+Tablib features a micro-framework for adding format support. The easiest way to understand it is to use it. So, let's define our own format, named *xxx*.
+
+1. Write a new format interface.
+
+    :class:`tablib.core` follows a simple pattern for automatically utilizing your format throughout Tablib. Function names are crucial.
+    
+    Example **tablib/formats/_xxx.py**: ::
+
+        title = 'xxx'
+    
+        def export_set(dset):
+            ....
+            # returns string representation of given dataset
+    
+        def export_book(dbook):
+            ....
+            # returns string representation of given databook
+        
+        def import_set(dset, in_stream):
+            ...
+            # populates given Dataset with given datastream
+    
+        def import_book(dbook, in_stream):
+            ...
+            # returns Databook instance
+    
+        def detect(stream):
+            ...
+            # returns True if given stream is parsable as xxx
+
+.. admonition:: Excluding Support
+
+
+    If the format excludes support for an import/export mechanism (*eg.* :class:`csv <tablib.Dataset.csv>` excludes :class:`Databook <tablib.Databook>` support), simply don't define the respecive functions. Appropriate errors will be raised.
+
+2. 
+
+    Add your new format module to the :class:`tablib.formats.avalable` tuple.
+
+3.
+    Add a mock property to the :class:`Dataset <tablib.Dataset>` class with verbose `reStructured Text`_ docstring. This alleviates IDE confusion, and allows for pretty auto-generated Sphinx_ documentation.
+
+4. Write respective :ref:`tests <testing>`.
+
+.. _testing:
+
+--------------
+Testing Tablib
+--------------
+
+Testing is crucial to Tablib's stability. This stable project is used in production by many companies and developers, so it is important to be certian that every version released is fully operational. When developing a new feature for Tablib, be sure to write proper tests for it as well.
+
+When developing a feature for Tablib, the easiest way to test your changes for potential issues is to simply run the test suite directly. ::
+
+	$ ./test_tablib.py
+
+
+`Hudson CI`_, amongst other tools, supports Java's xUnit testing report format. Nose_ allows us to generate our own xUnit reports. 
+
+Installing nose is simple. ::
+
+	$ pip install nose
+
+Once installed, we can generate our xUnit report with a single command. ::
+
+	$ nosetests test_tablib.py --with-xunit
+
+This will generate a **nosetests.xml** file, which can then be analyzed.

+
+
+.. _docs:
+
+-----------------
+Building the Docs
+-----------------
+
+Documentation is written in the powerful, flexible, and standard Python documentation format, `reStructured Text`_. 
+Documentation builds are powered by the powerful Pocoo project, Sphinx_. The :ref:`API Documentation <api>` is mostly documented inline throught the module.
+
+The Docs live in ``tablib/docs``. In order to build them, you will first need to install Sphinx. ::
+
+	$ pip install sphinx
+	
+
+Then, to build an HTML version of the docs, simply run the following from the **docs** directory: ::
+
+	$ make html	
+
+Your ``docs/_build/html`` directory will then contain an HTML representation of the documentation, ready for publication on most web servers.
+
+You can also generate the documentation in **ebpub**, **latex**, **json**, *&c* similarly.
+
+.. admonition:: GitHub Pages
+
+	To push the documentation up to `GitHub Pages`_, you will first need to run `sphinx-to-github`_ against your ``docs/_build/html`` directory. 
+	
+	GitHub Pages are powered by an HTML generation system called Jeckyl_, which is configured to ignore files and folders that begin with "``_``" (*ie.* **_static**).
+	
+
+
+
+
+
+	 and `sphinx-to-github`_. ::
+
+	Installing sphinx-to-github is simple. ::
+
+		$ pip install sphinx-to-github
+
+	Running it against the docs is even simpler. ::
+
+		$ sphinx-to-github _build/html
+	
+	Move the resulting files to the **gh-pages** branch of your repository, and push it up to GitHub.

+
+	$ pip install tablib
+
+Or, if you must: ::
+
+	$ easy_install tablib
+	
+But, you really shouldn't do that. 
+
+
+-------------------
+Download the Source
+-------------------
+
+You can also install tablib from source. The latest release (|version|) is available from GitHub.
+
+* tarball_
+* zipball_
+
+.. _
+Once you have a copy of the source, you can embed it in your Python package, or install it into your site-packages easily. ::
+
+    $ python setup.py install
+

+
+Tablib is partially dependent on the **pyyaml**, **simplejson**, and **xlwt** modules. To reduce installation issues, fully integrated versions of all required libraries are included in Tablib. 
+
+However, if performance is important to you (and it should be), you can install  **pyyaml** with C extentions from PyPi. ::
+
+	$ pip install PyYAML
+
+If you're using Python 2.5 (currently unsupported), you should also install the **simplejson** module. If you're using Python 2.6+, the built-in **json** module is already optimized and in use. ::
+
+	$ pip install simplejson
+

+
+Introduction
+============
+
+This part of the documentation covers all the interfaces of Tablib. 
+Tablib is a format-agnostic tabular dataset library, written in Python. It allows you to Pythonically import, export, and manipulate tabular data sets. Advanced features include, segregation, dynamic columns, tags / filtering, and seamless format import/exmport.
+
+
+Philosphy
+---------
+
+Tablib was developed with a few :pep:`20` idioms in mind.
+
+
+#. Beautiful is better than ugly.
+#. Explicit is better than implicit.
+#. Simple is better than complex.
+#. Complex is better than complicated.
+#. Readability counts.
+
+All contributions to Tablib should keep these important rules in mind.

+Quickstart
+==========
+
+
+.. module:: tablib
+
+
+Eager to get started? This page gives a good introduction in how to get started with Tablib. This assumes you already have Tablib installed. If you do not, head over to the :ref:`Installation <install>` section.
+
+First, make sure that:
+
+* Tablib is :ref:`installed <install>`
+* Tablib is :ref:`up-to-date <updates>`
+
+
+Lets gets started with some simple use cases and examples.
+
+
+
+------------------
+Creating a Dataset
+------------------
+
+
+A :class:`Dataset <tablib.Dataset>` is nothing more than what its name implies—a set of data.
+
+Creating your own instance of the :class:`tablib.Dataset` object is simple. ::
+
+    data = tablib.Dataset()
+    
+You can now start filling this :class:`Dataset <tablib.Dataset>` object with data.
+
+.. admonition:: Example Context
+     
+     From here on out, if you see ``data``, assume that it's a fresh :class:`Dataset <tablib.Dataset>` object.
+
+
+
+-----------
+Adding Rows
+-----------
+
+
+Let's say you want to collect a simple list of names. ::
+
+    # collection of names
+    names = ['Kenneth Reitz', 'Bessie Monke']
+
+    for name in names:
+        # split name appropriately
+        fname, lname = name.split()
+        
+        # add names to Dataset
+        data.append([fname, lname])
+
+You can get a nice, Pythonic view of the dataset at any time with :class:`Dataset.dict`.
+
+    >>> data.dict
+    [('Kenneth', 'Reitz'), ('Bessie', 'Monke')]
+
+
+
+--------------
+Adding Headers
+--------------
+
+
+It's time enhance our :class:`Dataset` by giving our columns some titles. To do so, set :class:`Dataset.headers`. ::
+
+    data.headers = ['First Name', 'Last Name']
+
+Now our data looks a little different. ::
+
+    >>> data.dict
+    [{'Last Name': 'Reitz', 'First Name': 'Kenneth'}, {'Last Name': 'Monke', 'First Name': 'Bessie'}]
+    
+
+
+
+--------------
+Adding Columns 
+--------------
+
+
+Now that we have a basic :class:`Dataset` in place, let's add a column of **ages** to it. ::
+
+    data.append(col=[22, 20], header='Age')
+    
+Let's view the data now. ::
+
+    >>> data.dict
+    [{'Last Name': 'Reitz', 'First Name': 'Kenneth', 'Age': 22}, {'Last Name': 'Monke', 'First Name': 'Bessie', 'Age': 20}]
+
+It's that easy.
+
+
+--------------
+Exporting Data
+--------------
+
+Tablib's killer feature is the ability to export your :class:`Dataset` objects into a number of formats.
+
+**Comma-Seperated Values** ::
+
+    >>> data.csv
+    Last Name,First Name,Age 
+    Reitz,Kenneth,22 
+    Monke,Bessie,20
+
+**JavaScript Object Notation** ::
+
+    >>> data.json
+    [{"Last Name": "Reitz", "First Name": "Kenneth", "Age": 22}, {"Last Name": "Monke", "First Name": "Bessie", "Age": 20}]
+
+
+**YAML Ain't Markup Language** ::
+
+    >>> data.yaml
+    - {Age: 22, First Name: Kenneth, Last Name: Reitz}
+    - {Age: 20, First Name: Bessie, Last Name: Monke}
+    
+
+**Microsoft Excel** ::
+
+    >>> data.xls
+    <censored binary data>
+
+
+------------------------
+Selecting Rows & Columns
+------------------------
+
+
+You can slice and dice your data, just like a standard Python list. ::
+
+    >>> data[0]
+    ('Kenneth', 'Reitz', 22)
+
+
+If we had a set of data consisting of thousands of rows, it could be useful to get a list of values in a column.
+To do so, we access the :class:`Dataset` as if it were a standard Python dictionary.  ::
+
+    >>> data['First Name']
+    ['Kenneth', 'Bessie']
+
+Let's find the average age. ::
+
+    >>> ages = data['Age']
+    >>> float(sum(ages)) / len(ages)
+    21.0
+
+
+
+-----------------------
+Removing Rows & Columns
+-----------------------
+
+It's easier than you could imagine. ::
+
+    >>> del data['Col Name']
+
+::
+
+    >>> del data[0:12]
+
+
+==============
+Advanced Usage
+==============
+
+
+This part of the documentation services to give you an idea that are otherwise hard to extract from the :ref:`API Documentation <api>`
+
+And now for something completely different.
+
+
+.. _dyncols:
+
+---------------
+Dynamic Columns
+---------------
+
+.. versionadded:: 0.8.3
+
+Thanks to Josh Ourisman, Tablib now supports adding dynamic columns. A dynamic column is a single callable object (*ie.* a function).
+
+Let's add a dynamic column to our :class:`Dataset` object. In this example, we have a function that generates a random grade for our students. ::
+
+    import random
+    
+    def random_grade(row):
+        """Returns a random integer for entry."""
+        return (random.randint(60,100)/100.0)
+    
+    data.append(col=[random_grade], header='Grade')
+
+Let's have a look at our data. ::
+
+    >>> data.yaml
+    - {Age: 22, First Name: Kenneth, Grade: 0.6, Last Name: Reitz}
+    - {Age: 20, First Name: Bessie, Grade: 0.75, Last Name: Monke}
+
+
+Let's remove that column.  ::
+
+    >>> del data['Grade']
+
+
+When you add a dynamic column, the first argument that is passed in to the given callable is the current data row. You can use this to perform calculations against your data row. 
+
+For example, we can use the data available in the row to guess the gender of a student. ::
+
+    def guess_gender(row):
+        """Calculates gender of given student data row."""
+        m_names = ('Kenneth', 'Mike', 'Yuri')
+        f_names = ('Bessie', 'Samantha', 'Heather')
+        
+        name = row[0]
+        
+        if name in m_names:
+            return 'Male'
+        elif name in f_names:
+            return 'Female'
+        else:
+            return 'Unknown'
+
+Adding this function to our dataset as a dynamic column would result in: ::
+
+    >>> data.yaml
+    - {Age: 22, First Name: Kenneth, Gender: Male, Last Name: Reitz}
+    - {Age: 20, First Name: Bessie, Gender: Female, Last Name: Monke}
+
+
+.. _tags:
+
+----------------------------
+Filtering Datasets with Tags
+----------------------------
+
+.. versionadded:: 0.9.0
+
+
+When constructing a :class:`Dataset` object, you can add tags to rows by specifying the ``tags`` parameter. 
+This allows you to filter your :class:`Dataset` later. This can be useful so seperate rows of data based on 
+arbitrary criteria (*e.g.* origin) that you don't want to include in your :class:`Dataset`.
+
+Let's tag some students. ::
+
+    students = tablib.Dataset()
+
+    students.headers = ['first', 'last']
+
+    students.append(['Kenneth', 'Reitz'], tags=['male', 'technical'])
+    students.append(['Bessie', 'Monke'], tags=['female', 'creative'])
+
+Now that we have extra meta-data on our rows, we can use easily filter our :class:`Dataset`. Let's just see Male students. ::
+
+
+    >>> data.filter(['male']).yaml
+    - {first: Kenneth, Last: Reitz}
+
+It's that simple. The original :class:`Dataset` is untouched.
+
+
+Excel Workbook With Multiple Sheets
+------------------------------------ 
+
+When dealine with a large number of :class:`Datasets <Dataset>` in spreadsheet format, it's quite common to group mulitple spreadsheets into a single Excel file, known as a Workbook. Tablib makes it extremely easy to build webooks with the handy, :class:`Databook` class.
+ 
+
+Let's say we have 3 different :class:`Datasets <Dataset>`. All we have to do is add then to a :class:`Databook` object... ::
+
+    book = tablib.Databook([data1, data2, data3])
+
+... and export to Excel just like :class:`Datasets <Dataset>`. ::
+
+    with open('students.xls', 'wb') as f:
+        f.write(book.xls)
+
+The resulting **students.xls** file will contain a seperate spreadsheet for each :class:`Dataset` object in the :class:`Databook`.
+
+.. admonition:: Binary Warning
+
+    Make sure to open the output file in binary mode.
+
+
+.. _seperators:
+
+----------
+Seperators
+----------
+
+.. versionadded:: 0.8.2
+
+When, it's often useful to create a blank row containing information on the upcomming data. So, 
+
+
+
+::
+
+    daniel_tests = [
+        ('11/24/09', 'Math 101 Mid-term Exam', 56.),
+        ('05/24/10', 'Math 101 Final Exam', 62.)
+    ]
+    
+    suzie_tests = [
+        ('11/24/09', 'Math 101 Mid-term Exam', 56.),
+        ('05/24/10', 'Math 101 Final Exam', 62.)
+    ]
+    
+    # Create new dataset
+    tests = tablib.Dataset()
+    tests.headers = ['Date', 'Test Name', 'Grade']
+
+    # Daniel's Tests
+    tests.append_seperator('Daniel\'s Scores')
+
+    for test_row in daniel_tests:
+       tests.append(test_row)
+
+    # Susie's Tests
+    tests.append_seperator('Susie\'s Scores')
+
+    for test_row in suzie_tests:
+       tests.append(test_row)
+
+    # Write spreadsheet to disk
+    with open('grades.xls', 'wb') as f:
+        f.write(tests.xls)
+
+The resulting **tests.xls** will have the following layout: 
+
+
+    Daniel's Scores:
+        * '11/24/09', 'Math 101 Mid-term Exam', 56.
+        * '05/24/10', 'Math 101 Final Exam', 62.
+
+    Suzie's Scores:
+        * '11/24/09', 'Math 101 Mid-term Exam', 56.
+        * '05/24/10', 'Math 101 Final Exam', 62.
+
+
+
+.. admonition:: Format Support
+
+    At this time, only :class:`Excel <Dataset.xls>` output supports seperators.

+r"""JSON (JavaScript Object Notation) <http://json.org> is a subset of

+interchange format.
+
+:mod:`simplejson` exposes an API familiar to users of the standard library
+:mod:`marshal` and :mod:`pickle` modules. It is the externally maintained
+version of the :mod:`json` library contained in Python 2.6, but maintains
+compatibility with Python 2.4 and Python 2.5 and (currently) has
+significant performance advantages, even without using the optional C
+extension for speedups.
+
+Encoding basic Python object hierarchies::
+
+    >>> import simplejson as json
+    >>> json.dumps(['foo', {'bar': ('baz', None, 1.0, 2)}])
+    '["foo", {"bar": ["baz", null, 1.0, 2]}]'
+    >>> print json.dumps("\"foo\bar")
+    "\"foo\bar"

+    >>> from StringIO import StringIO
+    >>> io = StringIO()
+    >>> json.dump(['streaming API'], io)
+    >>> io.getvalue()
+    '["streaming API"]'
+
+Compact encoding::
+
+    >>> import simplejson as json
+    >>> json.dumps([1,2,3,{'4': 5, '6': 7}], separators=(',',':'))
+    '[1,2,3,{"4":5,"6":7}]'
+
+Pretty printing::
+
+    >>> import simplejson as json
+    >>> s = json.dumps({'4': 5, '6': 7}, sort_keys=True, indent='    ')
+    >>> print '\n'.join([l.rstrip() for l in  s.splitlines()])
+    {
+        "4": 5,
+        "6": 7
+    }
+
+Decoding JSON::
+
+    >>> import simplejson as json
+    >>> obj = [u'foo', {u'bar': [u'baz', None, 1.0, 2]}]
+    >>> json.loads('["foo", {"bar":["baz", null, 1.0, 2]}]') == obj

+    True

+    >>> io = StringIO('["streaming API"]')
+    >>> json.load(io)[0] == 'streaming API'
+    True

+    ...     object_hook=as_complex)
+    (1+2j)
+    >>> from decimal import Decimal
+    >>> json.loads('1.1', parse_float=Decimal) == Decimal('1.1')
+    True
+
+Specializing JSON object encoding::

+        If skipkeys is false, then it is a TypeError to attempt
+        encoding of keys that are not str, int, long, float or None.  If
+        skipkeys is True, such items are simply skipped.
+
+        If ensure_ascii is true, the output is guaranteed to be str
+        objects with all incoming unicode characters escaped.  If
+        ensure_ascii is false, the output will be unicode object.
+
+        If check_circular is true, then lists, dicts, and custom encoded
+        objects will be checked for circular references during encoding to
+        prevent an infinite recursion (which would cause an OverflowError).
+        Otherwise, no such check takes place.
+
+        If allow_nan is true, then NaN, Infinity, and -Infinity will be
+        encoded as such.  This behavior is not JSON specification compliant,
+        but is consistent with most JavaScript based encoders and decoders.
+        Otherwise, it will be a ValueError to encode such floats.
+
+        If sort_keys is true, then the output of dictionaries will be
+        sorted by key; this is useful for regression tests to ensure
+        that JSON serializations can be compared on a day-to-day basis.
+
+        If indent is a string, then JSON array elements and object members
+        will be pretty-printed with a newline followed by that string repeated
+        for each level of nesting. ``None`` (the default) selects the most compact
+        representation without any newlines. For backwards compatibility with
+        versions of simplejson earlier than 2.1.0, an integer is also accepted
+        and is converted to a string with that many spaces.
+
+        If specified, separators should be a (item_separator, key_separator)
+        tuple.  The default is (', ', ': ').  To get the most compact JSON
+        representation you should specify (',', ':') to eliminate whitespace.
+
+        If specified, default is a function that gets called for objects
+        that can't otherwise be serialized.  It should return a JSON encodable
+        version of the object or raise a ``TypeError``.
+
+        If encoding is not None, then all input strings will be

+
+    Example of a bitmap that covers some of the area from cell A1 to cell B2.
+
+    Based on the width and height of the bitmap we need to calculate 8 vars:
+        col_start, row_start, col_end, row_end, x1, y1, x2, y2.
+    The width and height of the cells are also variable and have to be taken into
+    account.
+    The values of col_start and row_start are passed in from the calling
+    function. The values of col_end and row_end are calculated by subtracting
+    the width and height of the bitmap from the width and height of the
+    underlying cells.
+    The vertices are expressed as a percentage of the underlying cell width as
+    follows (rhs values are in pixels):
+
+           x1 = X / W *1024
+           y1 = Y / H *256
+           x2 = (X-1) / W *1024
+           y2 = (Y-1) / H *256
+
+           Where:  X is distance from the left side of the underlying cell
+                   Y is distance from the top of the underlying cell
+                   W is the width of the cell
+                   H is the height of the cell
+
+    Note: the SDK incorrectly states that the height should be expressed as a
+    percentage of 1024.
+
+    col_start  - Col containing upper left corner of object

+The  XF  record is able to store explicit cell formatting attributes or the
+attributes  of  a cell style. Explicit formatting includes the reference to
+a  cell  style  XF  record. This allows to extend a defined cell style with
+some  explicit  attributes.  The  formatting  attributes  are  divided into
+6 groups:
+
+Group           Attributes
+-------------------------------------
+Number format   Number format index (index to FORMAT record)
+Font            Font index (index to FONT record)
+Alignment       Horizontal and vertical alignment, text wrap, indentation,
+                orientation/rotation, text direction
+Border          Border line styles and colours
+Background      Background area style and colours
+Protection      Cell locked, formula hidden
+
+For  each  group  a flag in the cell XF record specifies whether to use the
+attributes  contained  in  that  XF  record  or  in  the  referenced  style
+XF  record. In style XF records, these flags specify whether the attributes
+will  overwrite  explicit  cell  formatting  when  the  style is applied to
+a  cell. Changing a cell style (without applying this style to a cell) will
+change  all  cells which already use that style and do not contain explicit
+cell  attributes for the changed style attributes. If a cell XF record does
+not  contain  explicit  attributes  in a group (if the attribute group flag
+is not set), it repeats the attributes of its style XF record.

+'''
+From BIFF8 on, strings are always stored using UTF-16LE  text encoding. The
+character  array  is  a  sequence  of  16-bit  values4.  Additionally it is
+possible  to  use  a  compressed  format, which omits the high bytes of all
+characters, if they are all zero.
+
+The following tables describe the standard format of the entire string, but
+in many records the strings differ from this format. This will be mentioned
+separately. It is possible (but not required) to store Rich-Text formatting
+information  and  Asian  phonetic information inside a Unicode string. This
+results  in  four  different  ways  to  store a string. The character array
+is not zero-terminated.
+
+The  string  consists  of  the  character count (as usual an 8-bit value or
+a  16-bit value), option flags, the character array and optional formatting
+information.  If the string is empty, sometimes the option flags field will
+not occur. This is mentioned at the respective place.
+
+Offset  Size    Contents
+0       1 or 2  Length of the string (character count, ln)
+1 or 2  1       Option flags:
+                  Bit   Mask Contents
+                  0     01H  Character compression (ccompr):

+                               1 = Uncompressed (16-bit characters)
+                  2     04H  Asian phonetic settings (phonetic):
+                               0 = Does not contain Asian phonetic settings
+                               1 = Contains Asian phonetic settings
