apt-mirror rewritten by Python

This project is started as a line by line translate from apt-mirror 0.5.4, so it is 100% compatible with apt-mirror config file.

In v0.2 it becomes an object-oriented program.

Usage:

Get help from http://apt-mirror.github.com/

Todo:

• Automatically check the checksum of index files before download archive files.
• If check failed, retry several times.
• threading.Queue for download threads.
• Accept command line arguments to override variables from mirror.list file.

Any improvement is welcome.
