| 16 | .SH NAME |
| 17 | vcdiff \- encoder/decoder for VCDIFF (RFC 3284) format |
| 18 | .SH DESCRIPTION |
| 19 | .HP |
| 20 | \fBvcdiff\fR {\fBencode\fR|\fBdelta\fR|\fBdecode\fR|\fBpatch\fR} |
| 21 | \fB\-dictionary\fR <filename> |
| 22 | [<options>] |
| 23 | .HP |
| 24 | \fBencode\fR or \fBdelta\fR: |
| 25 | create delta file from dictionary and target file |
| 26 | .HP |
| 27 | \fBdecode\fR or \fBpatch\fR: |
| 28 | reconstruct target file from dictionary and delta file |
| 29 | .HP |
| 30 | \fB\-dictionary\fR <filename> |
| 31 | .br |
| 32 | File containing dictionary data (also known as source data.) |
| 33 | Required for all operations. |
| 34 | .HP |
| 35 | \fB\-target\fR <filename> |
| 36 | .br |
| 37 | File name of the target file (unencoded data). |
| 38 | The default value (blank) causes vcdiff to use standard input for encode, |
| 39 | or standard output for decode. |
| 40 | .HP |
| 41 | \fB\-delta\fR <filename> |
| 42 | .br |
| 43 | File name of the delta file (encoded data). |
| 44 | The default value (blank) causes vcdiff to use standard output for encode, |
| 45 | or standard input for decode. |
| 46 | .HP |
| 47 | \fB\-checksum\fR |
| 48 | .br |
| 49 | Include an Adler32 checksum of the target data when encoding. |
| 50 | Default is false. |
| 51 | .HP |
| 52 | \fB\-interleaved\fR |
| 53 | .br |
| 54 | Use interleaved format. Default is false. |
| 55 | .HP |
| 56 | \fB\-stats\fR |
| 57 | .br |
| 58 | Write a report to stderr, containing the original target size, |
| 59 | compressed delta size, and compression percentage. |
| 60 | Default is false. |
| 61 | .HP |
| 62 | \fB\-target_matches\fR |
| 63 | .br |
| 64 | Find duplicate strings in target data as well as dictionary data. |
| 65 | Default is false. |
| 66 | .HP |
| 67 | \fB\-buffersize\fR <integer> |
| 68 | .br |
| 69 | The memory buffer size (in bytes) used for reading the input file. |
| 70 | Default is 1048576 (1 MB); if the input file is smaller than that, |
| 71 | the buffer will match the file size. This parameter does not usually |
| 72 | need to be specified. |
