- * 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
- * 2006/04/16 ... fixed crash grfio_find_file when file is not found.
