# RSS Display Script by Andrey Zakharov (admin@vaultsoft.ru) v0.1
#
# This script is designed to output story BODIES for most any RSS Feed.
#
# This script depends on wget, xsltproc, sed.  Please ensure it is installed and in your $PATH
# Debian: apt-get install wget xsltproc sed
#
# Usage:
# .conkyrc:	${execpi [time] /path/to/script/conky-rss.sh URI LIMIT}
#   URI = Location of feed, ex. http://bash.org.ru/rss/
#   LINES = How many items to display (default 5)
#
# Usage Example
#   ${execi 300 /home/youruser/scripts/conky-rss.sh http://www.foxnews.com/xmlfeed/rss/0,4313,1,00.rss 4}

# TODO quotes with quote symbols - respect LOCALE
