# Zip length operator
The length operator # applied on a Zip object returns the total number of entries that the Zip archive contains. The Zip.count property returns the same value.
Example
local compression = require "compression"
-- check parameters : the archive specified as argument
local archive = arg[1] or error("no archive specified")
-- open the archive
local z = compression.Zip(archive)
-- #z is equivalent to z.count
print(archive.." has a total of "..#z.." entries")
