| * 1999/10/23 acme cycxhw_t cleanup |
| * 1999/01/03 acme more judicious use of data types... |
| * uclong, ucchar, etc deleted, the u8, u16, u32 |
| * types are the portable way to go. |
| * 1999/01/03 acme judicious use of data types... u16, u32, etc |
| * 1998/12/26 acme FIXED_BUFFERS, CONF_OFFSET, |
| * removal of cy_read{bwl} |
| * 1998/08/08 acme Initial version. |
