+VLC Lua playlist modules should define two functions:
+ * probe(): returns true if we want to handle the playlist in this script
+ * parse(): read the incoming data and return playlist item(s)
+ The playlist is a table of playlist objects.
+ A playlist object has the following members:
+ .url: the item's full URL
+ .title: the item's title (OPTIONAL)
+ Invalid playlist items will be discarded by VLC.
+
+VLC defines a global vlc object with the following members:
+ * vlc.path: the URL string (without the leading http:// or file:// element)
+ * vlc.access: the access used ("http" for http://, "file" for file://, etc.)
+ * vlc.peek( <int> ): return the first <int> characters from the playlist file.
+ * vlc.readline(): return a new line of playlist data on each call.
+ THIS FUNCTION SHOULD NOT BE USED IN peek().
+ * vlc.decode_uri( <string> ): decode %xy characters in a string.
+ * vlc.resolve_xml_special_chars( <string> ): decode &abc; characters in a string.
+
+Lua scripts are tried in alphabetical order in the luaplaylist/ directory.
+
+Lua documentation is available on http://www.lua.org .
+VLC uses Lua 5.1
+All the Lua standard libraries are available.
