-O, --set-variable var=option\n\
Change the value of a variable.\n\
-s, --silent Only print errors. One can use two -s to make\n\
myisamchk very silent\n\
-v, --verbose Print more information. This can be used with\n\
--describe and --check. Use many -v for more verbosity!\n\

find out if the table is ok even without this switch\n\
-F, --fast Check only tables that hasn't been closed properly\n\
-C, --check-only-changed\n\
Check only tables that has changed since last check\n\
-f, --force Restart with -r if there are any errors in the table.\n\
States will be updated as with --update-state\n\
-i, --information Print statistics information about table that is checked\n\
-m, --medium-check Faster than extended-check, but only finds 99.99% of\n\
all errors. Should be good enough for most cases\n\

file when it's full)\n\
-e, --extend-check Try to recover every possible row from the data file\n\
Normally this will also find a lot of garbage rows;\n\
Don't use this option if you are not totally desperate.\n\
-f, --force Overwrite old temporary files.\n\
-k, --keys-used=# Tell MyISAM to update only some specific keys. # is a\n\
bit mask of which keys to use. This can be used to\n\
get faster inserts!\n\
-l, --no-symlinks Do not follow symbolic links. Normally\n\
myisamchk repairs the table a symlink points at.\n\
-r, --recover Can fix almost anything except unique keys that aren't\n\
unique.\n\
-n, --sort-recover Force recovering with sorting even if the temporary\n\
file would be very big.\n\
-o, --safe-recover Uses old recovery method; Slower than '-r' but can\n\
handle a couple of cases where '-r' reports that it\n\
can't fix the data file.\n\
--character-sets-dir=...\n\
Directory where character sets are\n\
--set-character-set=name\n\
Change the character set used by the index\n\
-t, --tmpdir=path Path for temporary files\n\
-q, --quick Faster repair by not modifying the data file.\n\
One can give a second '-q' to force myisamchk to\n\
modify the original datafile in case of duplicate keys\n\

-a, --analyze Analyze distribution of keys. Will make some joins in\n\
MySQL faster. You can check the calculated distribution\n\
by using '--describe --verbose table_name'.\n\
-d, --description Prints some information about table.\n\
-A, --set-auto-increment[=value]\n\
Force auto_increment to start at this or higher value\n\
If no value is given, then sets the next auto_increment\n\
value to the highest used value for the auto key + 1.\n\
-S, --sort-index Sort index blocks. This speeds up 'read-next' in\n\
applications\n\
-R, --sort-records=#\n\
Sort records according to an index. This makes your\n\
