0013 Takes user arguments and passes them to the main upload module CondDBFW.uploads, once the correct version exists.
0014 
0015 1. Ask the server corresponding to the database we're uploading to which version of CondDBFW it has (query the /conddbfw_version/ url).
0016 2. Decide which directory that we can write to - either the current local directory, or /tmp/random_string/.
0017 3. Pull the commit returned from the server into the directory from step 2.
0018 4. Invoke the CondDBFW.uploads module with the arguments given to this script.
