Acknowledgements
The File.which method was originally adopted from the FileWhich code posted
by Michael Granger on the now defunct rubygarden.org website. That code was
later replaced by a version based on the ruby-which library.
The File.nl_convert method is based on the nlcvt program found at
http://www.perl.com/language/ppt/src/nlcvt/nlcvt, written by Tom Christiansen.
The middle() method was provided by Shashank Date.
The binary?() method was based almost entirely on a blog post by Ryan
Davis (who, in turn, based his code on Perl's -B switch).
Future Plans
Add whatever other tools people think might be useful.
