-Legacy Attributes Extension
-===========================
-
-An extension to Python Markdown which implements legacy attributes.
-
-Prior to Python-Markdown version 3.0, the Markdown class had an `enable_attributes`
-keyword which was on by default and provided for attributes to be defined for elements
-using the format `{@key=value}`. This extension is provided as a replacement for
-backward compatibility. New documents should be authored using attr_lists. However,
-numerious documents exist which have been using the old attribute format for many
-years. This extension can be used to continue to render those documents correctly.
