[plt-scheme] getting console information using system

I wrote a module called proc-helper which is a wrapper around process. It
provides among other things a function run (string? . -> . string?)
which runs a command and returns the output. You're welcome to use it.
It's on my web page <http://www.ccs.neu.edu/home/dskippy/code/>

The library is pretty minimal and ment to solve a particular problem I
once had. So feel free to email me with bugs, additions, or changes you
