Subject Re: "input" and "output" subdirs in working directories

Thanks, Mark. What's your approach in CIPRES?  Do you use a flat 
structure for your working directories, or do you do something else?

simplify the job of returning to "input" and "output" files as discrete entities, so if you
don't know which files are which, you would have at least two coarse bins that can be returned
under separate banners.

and "output".  Is there a good reason for creating these two subdirectories?  Why not just
do all the work in the top level of the working directory?  It seems unnecessary.
