# uploader.py
# This script takes the filename of a list of wikis as argument and uploads their dumps to archive.org.
# The list must be a text file with the wiki's api.php URLs, one per line.
# Dumps must be in the same directory and follow the -wikidump.7z/-history.xml.7z format
# as produced by launcher.py (explained in https://code.google.com/p/wikiteam/wiki/NewTutorial#Publishing_the_dump ).
# Adjust your configuration; see below "Configuration goes here".
# You also need dumpgenerator.py in the same directory as this script.
