# Modified by Joseph Turian: I modified _fetch_feed such that there
# is parameter parse_date, with default False. (This changes the default
# behavior from the original function.) If False, we do not parse the date
# string into a datetime instance. Leaving it as a string makes it simpler
# to JSON the object.
# I also added some v2 methods, and added parameter baseurl to _fetch
"""Methods to interact with the FriendFeed API
Detailed documentation is available at
Many parts of the FriendFeed API require authentication. To support
authentication, FriendFeed gives users a "remote key" that they give to
third party applications to access FriendFeed. The user's nickname and that
remote key are passed as arguments to the constructor of the FriendFeed class,
and the credentials are automatically passed to all called methods. For
session = friendfeed.FriendFeed(nickname, remote_key)
entry = session.publish_message("Testing the FriendFeed API")
Users can get their remote key from You
should direct users who don't know their remote key to that page.
