- *

- *	2002/12/18... the original edition

- *	2003/01/23 ... Code correction

- *	2003/02/01 ... An addition and decryption processing are improved for LocalFile and two or more GRF(s) check processing.

- *	2003/02/02 ... Even if there is no grf it does not stop -- as -- correction

- *	2003/02/02... grf reading specification can be added later -- as -- correction (grfio_add function addition)

- *	2003/02 / 03... at the time of grfio_resourcecheck processing the entry addition processing method -- correction

- *	2003/02/05... change of the processing in grfio_init

- *	2003/02/23... a local file check -- GRFIO_LOCAL -- switch (Defoe -- Function Off)

- *      2003/10/21 ... The data of alpha client was read.

- *	2003/11/10 ... Ready new grf format.

- *	2003/11/11 ... version check fix & bug fix
