DESCRIPTION

       The command `tcbtest' is a utility for facility test and performance test.  This command is used in the following format.  `path' specifies
       the path of a database file.  `rnum' specifies the number of iterations.  `lmemb' specifies the	number	of  members  in  each  leaf  page.
       `nmemb'	specifies the number of members in each non-leaf page.	`bnum' specifies the number of buckets.  `apow' specifies the power of the
       alignment.  `fpow' specifies the power of the free block pool.

	      tcbtest write [-mt] [-cd|-ci|-cj] [-tl] [-td|-tb|-tt|-tx] [-lc num] [-nc num] [-xm num] [-df num]  [-ls  num]  [-ca  num]  [-nl|-nb]
	      [-rnd] path rnum [lmemb [nmemb [bnum [apow [fpow]]]]]
		     Store records with keys of 8 bytes.  They change as `00000001', `00000002'...
	      tcbtest read [-mt] [-cd|-ci|-cj] [-lc num] [-nc num] [-xm num] [-df num] [-nl|-nb] [-wb] [-rnd] path
		     Retrieve all records of the database above.
	      tcbtest remove [-mt] [-cd|-ci|-cj] [-lc num] [-nc num] [-xm num] [-df num] [-nl|-nb] [-rnd] path
		     Remove all records of the database above.
	      tcbtest  rcat [-mt] [-cd|-ci|-cj] [-tl] [-td|-tb|-tt|-tx] [-lc num] [-nc num] [-xm num] [-df num] [-ls num] [-ca num] [-nl|-nb] [-pn
	      num] [-dai|-dad|-rl|-ru] path rnum [lmemb [nmemb [bnum [apow [fpow]]]]]
		     Store records with partway duplicated keys using concatenate mode.

	      rnum [lmemb [nmemb [bnum [apow [fpow]]]]]
		     Perform queueing and dequeueing.
	      tcbtest misc [-mt] [-tl] [-td|-tb|-tt|-tx] [-nl|-nb] path rnum
		     Perform miscellaneous test of various operations.
