cat return code

[Paul E Condon <pecondon@quiknet.com>]

I'm attempting to use the pseudo-image-kit. I get error messages from
bash when I run it, so I'm attempting to debug the script. The error
message indicates a problem with comparing the return code from an
invocation of cat (concatenate and transfer). I look at the man page and
the info for cat hoping to find the defined return codes. The definition
does not seem to be in either place. What are the return codes for cat?
Where are they documented?
