| 6 | ** James Pearson 1/5/97 |
| 7 | ** Bug fix JCP 4/12/97 |
| 8 | ** Updated for 1.12 and added more Unix HFS filetypes. JCP 21/1/98 |
| 9 | ** |
| 10 | ** Things still to de done: |
| 11 | ** |
| 12 | ** Check SGI (XINET) structs |
| 13 | ** Check file size = finder + rsrc [+ data] is needed |
| 14 | ** AppleSingle/Double version 2? |
| 15 | ** Clean up byte order swapping. |
