This module intercepts all writes to STDOUT and lets you frobnicate the data with your own functions.

To install, do the usual dance:

less Makefile.PL
less lib/Tie/Hash/Longest.pm
less t/*
those being to ensure that I'm not being evil. Pay particular attention to t/01_defaults.t, as that generates code and executes it using system(). The fact that I can do this while you install a module demonstrates why you really need to pay attention to what's going on. I could just as easily do something horrible like trash your home directory.

then do this to install the module:

perl Makefile.PL
make
make test
make install (you may need to do this as root)
