| 35 | .Nm |
| 36 | .Ao Ar oldfile Ac Ao Ar newfile Ac Ao Ar patchfile Ac |
| 37 | .Sh DESCRIPTION |
| 38 | .Nm |
| 39 | generates |
| 40 | .Ao Ar newfile Ac |
| 41 | from |
| 42 | .Ao Ar oldfile Ac |
| 43 | and |
| 44 | .Ao Ar patchfile Ac |
| 45 | where |
| 46 | .Ao Ar patchfile Ac |
| 47 | is a binary patch built by bsdiff(1). |
| 48 | .Pp |
| 49 | .Nm |
| 50 | uses memory equal to the size of |
| 51 | .Ao Ar oldfile Ac |
| 52 | plus the size of |
| 53 | .Ao Ar newfile Ac , |
| 54 | but can tolerate a very small working set without a dramatic loss |
| 55 | of performance. |
