Subject: Re: warnings -w

From the "The Pragmatic Programmer's Guide"
-w

' Enables verbose mode. Unlike -v, reads program from standard input if no 
program files are present on the command line. We recommend running your 
Ruby programs with -w.

See other options at: http://www.rubycentral.com/book/rubyworld.html
