# Author: Bart Trojanowski <bart@jukie.net>
#
# This script intends to provide functionality similar to screen's
# copy-mode, but instead copy to the X clipboard. In order to copy to
# the clipboard we need either the Clipboard.pm from CPAN or the xclip
# command line utility.
#
# More details here: http://www.jukie.net/~bart/blog/tag/urxvt
#
# This script is based on the mark-urls script from the rxvt-unicode
# distribution.
