I'm a bit confused as to how to get the contents of a pipe. I think I want to use IO::Pipe and invoke the reader method. However, when I try
use IO; $pipe=new IO::Pipe; $pipe->reader(); while (<$pipe>){ print "> $_\n"; }
and save it as test.pl and then try cat test.pl|perl test.pl, I get no output.

(Ultimately, I want to set a procmail rule to send certain messages through a perlscript, and procmail wants to send these as a pipe...)

Of course I could be going about this completely wrong. It wouldn't be the first time.

Thanks for any help!
