+Add barcodes in webkit reports
+==============================
+
+Usage
+-----
+To embed a barcode image in a webkit report, use ``${helper.barcode(value)}``.
+Depending on template filtering, you might need to force not to use any filter
+    by doing ``${helper.barcode(value) | safe}``
+
+The function is defined as:
+  barcode(value, code='Code128', drawOpts=None, htmlAttrs=None)
+
+Parameters
+---------
+value
+  Value for barcode as expected by barcode type. Code128 takes a number or
+  numeric string
+code
+  barcode type. ReportLab 2.5 has the following codes: Codabar, Code11,
+  Code128, EAN13, EAN8, Extended39, Extended93, FIM, I2of5, MSI, POSTNET, QR,
+  Standard39, Standard93, USPS_4State
+drawOpts
+  dictionary of options for reportlab graphic. Depends on barcode type. Use
+  *format* to specify image format (default png), *width* to specify image
+  width in pixels (int), *height* to specify image height in pixels (int)
+htmlAttrs
+  dictionary of html attributes
+
+Requirements
+------------
+This module depends on reportlab and lxml, which are both part of the odoo
+installation.
+
+Contributors
+------------
