# Description:
# ------------
# This is the server-side portion of the Trusted User package
# manager.  This program will receive uploads from its client-side
# couterpart, tupkg.  Once a package is received and verified, it
# is placed in a specified temporary incoming directory where
# a separate script will handle migrating it to the AUR.  For
# more information, see the ../README.txt file.
#
# Python Indentation:
# -------------------
# For a vim: line to be effective, it must be at the end of the
# file.  See the end of the file for more information.
