| The test driver `lzotest' has grown into a fairly powerful program |
| of it's own. Here is a short description of the various options. |
| |
| [ to be written - this is only a very first draft ] |
| |
| |
| Usage: |
| ====== |
| |
| lzotest [option..] file... |
| |
| |
| Basic options: |
| ============== |
| |
| -m# compression method |
| -b# set input block size (default 262144, max 1310720) |
| -n# number of compression/decompression runs |
| -c# number of compression runs |
| -d# number of decompression runs |
| -S use safe decompressor (if available) |
| -A use assembler decompressor (if available) |
| -F use fast assembler decompressor (if available) |
| -O optimize compressed data (if available) |
| -s DIR process Calgary Corpus test suite in directory `DIR' |
| -@ read list of files to compress from stdin |
| -q be quiet |
| -L display software license |
| |
| |
| More about `-m': |
| ================ |
| |
| Use `-m' to list all available methods. |
| |
| You can select methods by number: |
| -m71 |
| |
| You can select methods by name: |
| -mlzo1x-1 |
| -mlzo1x-999 |
| -mlzo1x-1(11) |
| |
| You can select some predefined method groups: |
| -mall |
| -mlzo |
| -mm1 |
| -mm99 |
| -mm999 |
| -m1x999 |
| -m1y999 |
| |
| You can specify multiple methods/groups separated by ',': |
| -m1,2,3,4 |
| -m1,2,3,4,lzo1x-1,m99,81 |
| |
| And finally you can use multiple `-m' options: |
| -m962,972 -mm99,982,m1 |
| |
| |
| Other options: |
| ============== |
| |
| --max-data-length=LEN |
| |
| --dict=FILENAME |
| --max-dict-length=LEN |
| |
| --dump=FILENAME |
| |
| --adler32 |
| --crc32 |
| --execution-time |
| --totals |
| |
