# This script follows the interface of debathenificator scripts but
# does not itself use debathenificator because what we need to do
# doesn't fit the model.  Most of the code here is copied from
# debathenificator, but:
#
# 1. We don't do anything on platforms which already have a usable
#    version of cyrus-sasl2-mit.
#
# 2. The version check is modified to check the native version of
#    cybus-sasl2 (which we want to match) rather than cyrus-sasl2-mit
#    (which does not exist on most of the platforms we want to build
#    for).
#
# 3. cmd_source creates the source package by combining the tarfile
#    from the native cyrus-sasl2 package with the packaging materials
#    stored here (which are based on the now-defunct cyrus-sasl2-mit
#    but are heavily modified).
