       `path'  specifies  the  path  of	a database file.  `tnum' specifies the
       number of running threads.  `rnum' specifies the	number of  iterations.
       `bnum'  specifies the number of buckets.	 `apow'	specifies the power of
       the alignment.  `fpow' specifies	the power of the free block pool.

	      tchmttest	write [-tl] [-td|-tb|-tt|-tx] [-rc num]	[-xm num] [-df
	      num] [-nl|-nb] [-as] [-rnd] path tnum rnum [bnum [apow [fpow]]]
		     Store records with	keys  of  8  bytes.   They  change  as
		     `00000001', `00000002'...
	      tchmttest	 read  [-rc  num]  [-xm	num] [-df num] [-nl|-nb] [-wb]
	      [-rnd] path tnum
		     Retrieve all records of the database above.
	      tchmttest	remove [-rc num] [-xm num] [-df	num] [-nl|-nb]	[-rnd]
	      path tnum
		     Remove all	records	of the database	above.
	      tchmttest	 wicked	 [-tl]	[-td|-tb|-tt|-tx] [-nl|-nb] [-nc] path
	      tnum rnum
		     Perform updating operations selected at random.
	      tchmttest	typical	[-tl] [-td|-tb|-tt|-tx]	[-rc  num]  [-xm  num]
	      [-df  num]  [-nl|-nb] [-nc] [-rr num] path tnum rnum [bnum [apow
	      [fpow]]
		     Perform typical operations	selected at random.
	      tchmttest	race  [-tl]  [-td|-tb|-tt|-tx]	[-xm  num]  [-df  num]
	      [-nl|-nb]	path tnum rnum [bnum [apow [fpow]]
		     Perform race condition test.

       Options feature the following.

	      -tl : enable the option `HDBTLARGE'.
	      -td : enable the option `HDBTDEFLATE'.
	      -tb : enable the option `HDBTBZIP'.
	      -tt : enable the option `HDBTTCBS'.
	      -tx : enable the option `HDBTEXCODEC'.
	      -rc num :	specify	the number of cached records.
	      -xm num :	specify	the size of the	extra mapped memory.
	      -df num :	specify	the unit step number of	auto defragmentation.
	      -nl : enable the option `HDBNOLCK'.
	      -nb : enable the option `HDBLCKNB'.
	      -as : use	the function `tchdbputasync' instead of	`tchdbput'.
	      -rnd : select keys at random.
	      -wb : use	the function `tchdbget3' instead of `tchdbget'.
	      -nc : omit the comparison	test.
	      -rr num :	specify	the ratio of reading operation by percentage.
