What is the correct and reliable way to munge the command line of a
program on HP-UX (3.01 on the hp9000s800) so that you can change what
ps(1) shows?  How exactly does ps decide what to output as the
"command line"?  

I would be grateful if someone could send me some example code.  For
instance, ftpd (the newest version from uunet, which I have installed)
tries to do this, but ps shows the command as "[ftpd]".  Ftpd writes
over both the argv and envp strings, which are located at the bottom
of the user stack, is this a good idea?  Wouldn't it be best to first
copy the environment strings somewhere else and make environ point
there?
