This looks like a Linux OS-specific thing.  Line 34 of netgen (which is
a shell script) is:

       *) arglist="$arglist${arglist:+ }\"${i//\"/\\\"}\"";;

My guess is that this syntax may be sh-specific and not necessarily
bash-compliant.  The top of that file has:


which may be relying on the fact that on my system (Fedora Core), bash
and sh are the same.

On the other hand, it appears that qflow succeeded in running DRC,
which requires running magic, which has a similar startup script with
the same line, so I'm not sure why that would run, but netgen would

Can you run netgen from the command line?  Does it produce the same
