# Parse XML RSS feeds into BARF blog posts for the specified site.
|
|
# If a post with a matching _link_ already exists, no new post will
|
|
# be created for that item. Tags will be created according to the rules
|
|
# defined in the get_tags() function.
|
|
#
|
|
# The file argument should point to a file containing one line per feed,
|
|
# with fields separated by the | character, in the following format:
|
|
#
|
|
# http://feeds.feedburner.com/ImNotReallyStanleyLieber|stanleylieber
|
|
#
|
|
# where the first field is the feed URL and each addition field is a tag.
|
|
#
|
|
# Requires 20h's xmlpull and rssread.
