+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
