office-gobmx/bin/get-bugzilla-attachments-by-mimetype
Michael Stahl 065299f78c get-bugzilla-attachments-by-mimetype: disable bz.apache.org 
It's ridiculously un-cooperative, and if you accidentally run the script
from a static IP you won't be able to look at that bugzilla for a while,
which is tragic because it holds important historical info hostage.

# prefixes to indicate which bug-tracker, e.g.
#
# fdo-bugid-X.suffix
# rhbz-bugid-X.suffix
# moz-bugid-X.suffix
#
# where X is the n'th attachment of that type in the bug
#
# The results are stored in the current directory, categorized by the
# extension of the downloaded file. When a file already exists, it is assumed
# it is already downloaded by a previous run, and up-to-date.
