Sure - most of the work is done by this ruby module:

http://git.openstreetmap.org/chef.git/blob/HEAD:/cookbooks/tile/files/default/ruby/expire.rb

which is invoked from a small script:

http://git.openstreetmap.org/chef.git/blob/HEAD:/cookbooks/tile/templates/default/expire-tiles.erb

That in turn is run by the replication code, giving the name of the 
replication diff file fetched by osmosis as argument.
