+API Documentation for the ebook editing tools
+===============================================
+
+The ebook editing tools consist of a
+:class:`calibre.ebooks.oeb.polish.container.Container` object that represents a
+book as a collection of HTML + resource files, and various tools that can be
+used to perform operations on the container. All the tools are in the form of
+module level functions in the various ``calibre.ebooks.oeb.polish.*`` modules.
+
+.. module:: calibre.ebooks.oeb.polish.container
+    :synopsis: The container object used to represent a book as a collection of its constituent HTML files.
+
+You obtain a container object for a book at a path like this::
+
+    from calibre.ebooks.oeb.polish.container import get_container
+    container = get_container('Path to book file', tweak_mode=True)
+
+If you are writing a plugin for the ebook editor, you get the current container
+for the book being edited like this::
+
+    from calibre.gui2.tweak_book import current_container
+    container = current_container()
+    if container is None:
+        # No book has been opened yet
