+attr_formatter.py
+
+This module contains a function `format` that modifies a BeautifulSoup object in place.
+The function searches for all elements with the attribute "dj-attr".
+The value of "dj-attr" is expected to be a string with pairs of attributes and values separated by semicolons (;),
+and each pair separated by tildes (~). For each found element, it splits the "dj-attr" value into attribute-value pairs,
+formats the value into a Django template variable format (i.e., "{{ value }}"), and assigns it to the corresponding
+attribute of the element. After processing all attribute-value pairs, it removes the "dj-attr" attribute from
+the element.
+
+Example:
+    If an element is <div dj-attr="class;my-class~id;my-id"></div>,
+    after processing, it becomes <div class="{{ my-class }}" id="{{ my-id }}"></div>.

+
+This module contains a function `format` that modifies a BeautifulSoup object in place.
+The function searches for all elements with the attribute "dj-block". The value of "dj-block" is expected to be a
+string representing the name of a Django block. For each found element, it inserts Django block tags before and after
+the element, using the value of "dj-block" as the block name. Then it removes the "dj-block" attribute from the element.
+
+Example:
+    If an element is <div dj-block="content">Content</div>,
+    after processing, it becomes {% block content %}Content{% endblock %}.
