Package: python-fastimport
Version: 0.9.0-2
Severity: wishlist
Tags: upstream patch
It can be hard to get started with a new module without some
documentation or examples to indicate how it is meant to be used.
Maybe some docstrings could help?
No claim of reliability intended. I followed the rule, "when in
doubt, make something up".

-This module provides core processing functionality including an abstract class

+This module provides the skeleton of a fast-import backend.
+To import from a fast-import stream to your version-control system:
+
+ - derive a class from the abstract ImportProcessor class and
+ implement the *_helper methods.
+
+ - parse a fast-import stream into a sequence of commands, for example
+ using the helpers from the parser module.
+
+ - pass that command sequence to the process method of your processor.

+See git-fast-import.1 for the meaning of each command and the
+processors package for examples.
