As an user, I've got concerns with how scripts work in shells. I've 
used checkbashism to try and elimanate them, but don't know if it 
finds all of them. I've even run into an issue where bash worked 
with a for loop, but after upgrading to a newer version it no longer 
worked.

I've got a project that I took over way back in 2004, and it used 
busybox for most things, but did included the full bash to run 
scripts? It might work with a busybox shell, but going thru a 2000+ 
line script to check for any issues has prompted me to just leave 
the 877480 byte bash as part of the iso image. 

Is there a program that can fully check scripts for bashisms or 
other problems. 

Thanks for the great work on the busybox project...
