Changes fall into these categories: 1. Avoid pathological string building. Loops over x = x .. "foo" can become very slow. Instead, use strbuf.lua, table.concat, or just one continuous concatenation; a = x .. y .. z is one operation, better than a = x .. y; a = a .. z 2. Use hex-escaped strings instead of string.char. I find this more readable in many cases, and it avoids a table lookup and function call. 3. Don't duplicate code. A few libraries and scripts had re-implemented stdnse.generate_random_string or openssl.rand_bytes.
Here is some documentation for Nmap, but these files are much less comprehensive than what you'll find at the actual Nmap documentation site ( http://nmap.org ).
