1/19    How do I read from an input  pipe in sh or perl?  I need a little
        script that can read in "echo foo | myScript"
        \_ you use 'read' in sh, and <> in perl. i.e
           while (<>) print $_; is perl equivalent to /bin/cat
        \_ In perl: explicit is <STDIN>; magical is <>
        \_ In csh: accessing $< gives you a line from stdin
