Retrieves a list of music from a DAAP server. The list includes artist names and album and song titles. Output will be capped to 100 items if not otherwise specified in the 'daap_item_limit' script argument. A 'daap_item_limit' below zero outputs the complete contents of the DAAP library. Based on documentation found here: http://www.tapjam.net/daap/. SYNTAX: http.pipeline: If set, it represents the number of HTTP requests that'll be pipelined (ie, sent in a single request). This can be set low to make debugging easier, or it can be set high to test how a server reacts (its chosen max is ignored). http.useragent: The value of the User-Agent header field sent with requests. By default it is ''Mozilla/5.0 (compatible Nmap Scripting Engine http://nmap.org/book/nse.html)''. A value of the empty string disables sending the User-Agent header field. http-max-cache-size: The maximum memory size (in bytes) of the cache. daap_item_limit: Changes the output limit from 100 songs. If set to a negative value, no limit is enforced.
