# Add a feed option to execute a command before or after updating the feed.

# This is useful if, for example, you have a file: feed that's generated on the
# fly by a screen-scraping program.
# Usage example:
# feed 3h file:/tmp/scraped.rss
#     pre-execute scrape http://somewhere/ >/tmp/scraped.rss
#     post-execute rm /tmp/scraped.rss
