# * Simpler, more robust version of tinyurl (doesn't rely on html output)
# * Echo's urls from all channels that are over the plugin's maxlen value
# in a shortened format.
# * allows for manual shortening of urls
# * set config variable 'shortener' to one of:
#
# Value Service used
# ----- ------------
# qurl http://qurl.com/
# tinyurl http://tinyurl.com/
# isgd http://is.gd/
# trim http://tr.im/
# bitly http://bit.ly/
#
# Note: attempting to use the bitly shortener without setting the
# bitly_login and bitly_key config variables will fail.
#
# Note: 'trim' and 'bitly' shorteners require the 'rubygems' and
# 'json' ruby modules.
#
# 2009-12-12, FlashCode <flashcode@flashtux.org>
# version 1.5: fix wrong license in register()
# 2009-11-29, penryu <penryu@gmail.com>
# version 1.4: fixed URI encoding bug, added shorteners
# changed default shortener, as qurl is _slow_
# 2009-11-29, penryu <penryu@gmail.com>
# version 1.3: add bit.ly shortener routine
# add ability to choose shortener from config
# 2009-05-02, FlashCode <flashcode@flashtux.org>:
# version 1.2: sync with last API changes
# 2008-11-11, FlashCode <flashcode@flashtux.org>:
# version 1.1: conversion to WeeChat 0.3.0+
