shell script equivalent to cflow ?

[Michael Neuffer]

Hi Folks


Does anyone know of an equivalent to cflow for shell scripts ?

I've taken over a set of production machines that have obviously
not been properly maintained for the last few years and where
several generations of developers with various skill levels 
have added scripts on top of scripts on top of scripts.

Now I've been tasked to document all of this and after that we will 
rebuild the environment cleanly.

I believe that I have once seen some piece of software that 
did for shell scripts pretty much the same what cflow does for C 
code. Unfortunately I can't remember any details about it anymore
and thus can't find it.

Has anybody any ideas wether I'm just hunting a false memory
or where I could find it if it indeed exists ?

I know it could neither be very accurate nor complete
but it would help me tremendously.

Cheers
