| This code is for creating and interpreting `vcdiff'. |
| |
| The full specification of the vcdiff format is in the draft RFC |
| (draft-korn-vcdiff-01.txt), and some discussion of how to *generate* |
| diffs may be found there as well. |
| |
| This README provides an informal summary of how we implement vcdiff, |
| in three sections: |
| |
| 1. The vcdiff format and how to use it. |
| 2. Generating vcdiffs. |

| A vdiff consists of a 4 byte header, followed by a series of |
| "sections". Each section is |
| |
| A 4 byte header -- the letters "VCD" with their eighth bits set, |
| then a format version number: |
| |
| byte 1 byte 2 byte 3 byte 4 |
