 *
 * 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.
