- update the man page!
- document "-f" switch
- look if other unix variants have a similar mechanism
- implement some list syntax for the command line arguments

a neat concept.  this is something members of the local computer club have
been wanting.  i have a question / observation i would like to make.  it is
not clear how to use this software most effectively.  for example, i have a
system with 3 hard drives (two on removeable sleds), 2 cd rom drives, 2 tape
drives and the cd and tape drives are in an external shoebox.  here is what
i have seen so far.

1. changing a scsi sled.  doesn't seem to be much of a problem.  i am doing
the following:
  scsiadd -r 2
  power off the sled and remove it.
  reinstall the sled
  
  now, am i supposed to power on the sled then give the scsiadd command or
  do i give the command to add a device first then power on the sled?  once
  i did this and there was no problem, the second time i had a scsi bus reset.
  i was hoping to avoid the reset.  what should we be expecting here?

2. it would be nice to power off all the shoebox devices.  removing them is
no problem.  but when you issue a scsiadd command you can only specify one
device.  the command seems to hang waiting for that device.  i guess i can
background this so i can disable the 4 devices with four calls.  but it would
be nice if i can specify a list of devices (comma seperated or maybe enclose
in quotes) to add.

3. when the command tries to disable a scsi device an error message about
that device.  No such device is printed.  should this happen (i know that
that device isn't there because i just removed it) or should the error be
silent?
