-
-    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
-    row_start  - Row containing top left corner of object
-    x1  - Distance to left side of object
-    y1  - Distance to top 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.
-

-0       1 or 2  Length of the string (character count, ln)

-## When reading Japanese chars, it happens that a stream returns a
-## 'char' of length 2. This looks like  a  bug  in the appropriate
-## codecs - but I'm  rather  unsure about this. Anyway, if this is
-## the case, I'm going to  split  this string into a list of chars
-## and put them  on  hold, ie. on a  buffer. Next time when called
-## we read from buffer until buffer is empty.
-## wh: nov, 25th -> problem does not appear in Python 2.4.0.c1.

-<h3>State of Documentation</h3>
-
-<p>
-This documentation is currently incomplete. There may be methods and
-classes not included and any item marked with a <em
-style="color:red;">[NC]</em> is not complete and may have further
-parameters, methods, attributes and functionality that are not
-documented. In these cases, you'll have to refer to the source if the
-documentation provided is insufficient.

-
-<h2>Module Contents <em style="color:red;">[NC]</em></h2>
-<dl>
-  <dt><b>easyxf</b> (function)</dt>
-  <dd>
-  <p>
-  This function is used to create and configure XFStyle objects
-  for use with (for example) the Worksheet.write method.
-  </p>
-  <dl>
-    <dt><i>strg_to_parse</i></dt>
-    <dd>
-      <p>
-      	A string to be parsed to obtain attribute values for Alignment, Borders, Font,
-      	Pattern and Protection objects. Refer to the examples
-      	in the file .../examples/xlwt_easyxf_simple_demo.py and to the xf_dict
-      	dictionary in Style.py. Various synonyms including color/colour, center/centre and gray/grey
-      	are allowed. Case is irrelevant (except maybe in font names). '-' may be used instead
-      	of '_'.<br />
-		Example: "font: bold on; align: wrap on, vert centre, horiz center"
-      </p>
-    </dd>
-    <dt><i>num_format_str</i></dt>
-    <dd>
-      <p>
-		To get the "number format string" of an existing cell whose format you want to reproduce,
-		select the cell and click on Format/Cells/Number/Custom. Otherwise, refer to Excel help.<br />
-		Examples: "#,##0.00", "dd/mm/yyyy"
-      </p>
