1999-11-02	Mika Kuoppala <[e-mail]>

	* 0.01: initial version

1999-11-30      James Manning <[e-mail]>

	* 0.06: tiobench.sh fixes and block improvements 

1999-12-01	Mika Kuoppala <[e-mail]>

	* 0.07:	Long option parsing. Typo fixes by James.

	* 0.08:	Long option parsing now behind define. 
	Some systems are missing getopt_long :( This has to 
	solved out more general way in future.

	* 0.09: pthread_init_attr, pthread_destroy_attr 
	were missing. Sami noticed this with Irix

	* 0.10: Makefile cleanup. _GNU_SOURCE and _REENTRANT added 
	to tiotest.c for correct behaviour of system header files.

	* 0.11: tiobench.pl by James added to distribution. Changes to
	output formatting in tiotest.c.

1999-12-02       Mika Kuoppala <[e-mail]>

	* 0.12:	Sequential writing is now an option.
	This prevents write phase fragmentation of test files. 
	Suggested by Jakob

1999-12-04       Mika Kuoppala <[e-mail]>

	* 0.13:	Tiobench.pl has now seeks as an option, 
	It also finds tiotest better. Few other minor fixes and 
	typos corrected.

1999-12-05       James Manning <[e-mail]>

	* 0.14: Minor tiobench.pl cleanups

1999-12-07       Mika Kuoppala <[e-mail]>
	
	* 0.15: Seeks are now truely random and unique for each thread.

2000-01-04       James Manning <[e-mail]>

	* 0.16: tiobench.pl now figures default filesize by peeking 
	available physical ram.

2000-02-04       Mika Kuoppala <[e-mail]>

	* 0.20:	 Makefile is now hopefully more portable.
	Rewrote the random seeks handling totally. It can now handle
	systems with 15bit RAND_MAX correctly.
	Added system and user time as an measured value.
	Rewrote output for both verbose and terse options.
	Quick hacked tiobench.pl to accept new terse output.
	Minor cleanups and fixes here and there.
	Moved tiobench.sh to funnyscripts directory in order to
	lessen confusion among users.
	Added BUGS file into distribution.

2000-02-04       Mika Kuoppala <[e-mail]>

	* 0.21	 Few fixes in output handling.
	James found out that in glibc 2.1.(x<3) rand_r is broken.
	This should be fixed by how tiotest handles rand_r now.
