3"""Example post-receive hook based on git-multimail.
4
5The simplest way to use git-multimail is to use the script
6git_multimail.py directly as a post-receive hook, and to configure it
7using Git's configuration files and command-line parameters.  You can
8also write your own Python wrapper for more advanced configurability,
9using git_multimail.py as a Python module.
10
11This script is a simple example of such a post-receive hook.  It is
12intended to be customized before use; see the comments in the script
13to help you get started.
14
15Using git-multimail as a Python module as done here provides more
16flexibility.  It has the following advantages:
17
18* The tool's behavior can be customized using arbitrary Python code,
19  without having to edit git_multimail.py.
20
21* Configuration settings can be read from other sources; for example,
22  user names and email addresses could be read from LDAP or from a
23  database.  Or the settings can even be hardcoded in the importing
24  Python script, if this is preferred.
25
26This script is a very basic example of how to use git_multimail.py as
27a module.  The comments below explain some of the points at which the
28script's behavior could be changed or customized.
