AUTHOR
This program, its manual page, and the Debian package were written by Russell Coker <russell@coker.com.au>.
FEATURES
Uses popen (3) for output so that shell expansion gets performed. If you want such shell expansion then you must ensure that you quote the parameters correctly so that they get expanded by popen (3) not the shell that calls funnel.
