Example
-- inspect a zip archive
local compression = require "compression"
local console = require "console"
-- check parameters : the archive specified as argument
local archive = arg[1] or error("no archive specified")
-- open the archive
local z = compression.Zip(archive)
console.writeln("Inspecting "..archive.."...")
console.writecolor("lightgreen", "Total size:\t")
console.writeln(z.size.." bytes")
console.writecolor("lightgreen", "Total entries:\t")
console.writeln(z.count)
console.writecolor("lightgreen", "ZIP64:\t\t")
console.writeln(z.iszip64 and "enabled" or "disabled")
