+Custom content processors for Moban
+----------------------------------------
+
+Since version 0.7.7, it became easy to write a content processor for moban.
+What you need is a content processing function, which will be fed the
+content of `template_file` and which is expected to return a string. And
+decorate your function with `ContentProcessor`:
+
+.. code-block:: python
+
+    @ContentProcessor('strip', 'Stripping', 'Stripped'):
+    def strip(template_file: str) -> str:
