Nobu:

I tried using File.read and it worked successfully.
I have also made other experiments which lead me to believe that pipes
work as expected:

`perl cwd.prl`   ==> Worked correctly
`@[]cwd.com`     ==> Worked correctly (VMS .com files are akin to
                     .BAT files on MS-DOS)

I've also tried using miniruby and wrapping the call to the ruby script
in perl and DCL (.com file), each of which returned the output:

C==character of a path

C\nC\nC\n

which prints as one would expect:

C
C
C

It seems only to occur when I invoke ruby from ruby.
