The > and < operators specify output or input *files*; specifically,
this command is going to look for a file in the current directory called
'zcat' that it can use as input.

The standard mechanism for choosing 'stdin' as your file is to use '-'
as the filename.  So you might try:

$ zcat docstrip.dvi.gz | xdvi - (Note, this yields a "No such file or
directory" retort.  Any other ideas for script?  Rob Mohr)

I have no idea if xdvi supports that, though.
