fies the path of a database file. `tnum' specifies the number of running threads. `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.
tcbmttest write [-tl] [-td|-tb|-tt|-tx] [-xm num] [-df num] [-nl|-nb] [-rnd] path tnum rnum [lmemb [nmemb [bnum [apow [fpow]]]]]

tcbmttest read [-xm num] [-df num] [-nl|-nb] [-wb] [-rnd] path tnum
Retrieve all records of the database above.
tcbmttest remove [-xm num] [-df num] [-nl|-nb] [-rnd] path tnum
