The problem, I think, is that I seem to have to fire up the external viewers (like gv) as background processes, i.e. the code is like: system("gv foo.ps &"); If gv then fails, I seem nonetheless to get an exit code of 0, so I have no way to find out from the exit code if the system call has really succeeded in the sense we want. The reason why I send the process to the background is that otherwise, the rest of the script is blocked until the external app is closed. Of course I could try to capture errors written to stderr somehow, but I think this would make texdoctk dependent on which shell is actually used, because this redirection is I think not the same for all shells (let alone in other OSs). This would be bad, because in the interest of portability, no assumptions should be made about the shell. So, for now, I think I'll have to leave it as it is. Sorry.
