+ * Parses a simple line based scriptfile with some limitations:
+ * first function (starting a block) must be a read-command,
+ * last must be a write-command (ending this block).
+ *
+ * read- and write-commands have hard coded parameters, number#1 being a filetype.
+ * Classes handling certain filetypes must be of type CFile.
+ * Custom functions will be passed to CFile::callFunc().
+ *
+ * On error ParserError will be thrown.
