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 ]
|

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

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
|
||
|
|
||
|
|
||
|
